代谢
邻苯二甲酸二辛酯(DnOP)被代谢为其水解单酯,邻苯二甲酸单正辛酯(MnOP)和其他氧化产物。在通过灌胃给予DnOP的Sprague-Dawley大鼠中,这些氧化代谢物之一,邻苯二甲酸单(3-羧基丙基)(MCPP)的尿液中水平比MnOP高出约560倍。此外,MCPP也出现在给予邻苯二甲酸二异辛酯(DiOP)、邻苯二甲酸二异壬酯(DiNP)、邻苯二甲酸二异癸酯(DiDP)、邻苯二甲酸二(2-乙基己基)酯和邻苯二甲酸二正丁酯(DBP)的大鼠尿液中,尽管其浓度远低于给予相似浓度DnOP的大鼠。在暴露大鼠中,MCPP的尿液中浓度比高分子量邻苯二甲酸酯DiOP、DiNP和DiDP的水解单酯要高得多,这表明这些单酯可能是其前体邻苯二甲酸酯暴露的差标志物,并可能解释为什么在人类群体中这些单酯代谢物的检测频率相对较低。在267份人类尿液中也测量了MCPP和MnOP。MCPP的频繁检测和高尿液浓度表明,DnOP的暴露可能比仅根据MnOP的测量结果认为的要高。然而,因为MCPP也是大鼠中DBP和其他邻苯二甲酸酯的次要代谢物,并且啮齿动物和人类的邻苯二甲酸酯代谢可能不同,所以需要更多的关于MCPP的吸收、分布、代谢和排泄的数据,以完全理解人类通过尿液中的MCPP浓度暴露于DnOP的程度。
... Di-n-octyl phthalate (DnOP) is metabolized to its hydrolytic monoester, mono-n-octyl phthalate (MnOP), and other oxidative products. The urinary levels of one of these oxidative metabolites, mono-(3-carboxypropyl) phthalate (MCPP), were about 560-fold higher than MnOP in Sprague-Dawley rats dosed with DnOP by gavage. Furthermore, MCPP was also found in the urine of rats dosed with di-isooctyl phthalate (DiOP), di-isononyl phthalate (DiNP), di-isodecyl phthalate (DiDP), di-(2-ethylhexyl) phthalate, and di-n-butyl phthalate (DBP), although at concentrations considerably lower than in rats given similar concentrations of DnOP. The comparatively much higher urinary concentrations of MCPP than of the hydrolytic monoesters of the high-molecular-weight phthalates DiOP, DiNP, and DiDP in the exposed rats suggest that these monoesters may be poor biomarkers of exposure to their precursor phthalates and may explain the relatively low frequency of detection of these monoester metabolites in human populations. MCPP and MnOP were also measured in 267 human urine samples. The frequent detection and higher urinary concentrations of MCPP than MnOP suggest that exposure to DnOP might be higher than previously thought based on the measurements of MnOP alone. However, because MCPP is also a minor metabolite of DBP and other phthalates in rats, and the metabolism of phthalates in rodents and humans may differ, additional data on the absorption, distribution, metabolism, and elimination of MCPP are needed to completely understand the extent of human exposure to DnOP from the urinary concentrations of MCPP.

代谢
邻苯二甲酸二辛酯(DnOP)的代谢导致一个酯键的水解,产生邻苯二甲酸单辛酯(MnOP),随后代谢形成氧化代谢物。在成年雌性Sprague-Dawley大鼠中,通过监测口服给予DnOP(300 mg/kg)后尿液中DnOP代谢物的排泄来研究DnOP的毒代动力学。使用真实标准,明确建立了尿液中邻苯二甲酸(PA)、MnOP和主要的DnOP代谢物,邻苯二甲酸单(3-羧基丙基)酯(MCPP)的存在。此外,根据它们的色谱行为和质谱裂解模式,鉴定出了另外五种尿液DnOP氧化代谢物。这些DnOP氧化代谢物被假设为邻苯二甲酸单羧甲基酯(MCMP)、邻苯二甲酸单(5-羧基正戊基)酯(MCPeP)、邻苯二甲酸单(7-羧基正庚基)酯(MCHpP)以及邻苯二甲酸单羟基辛酯(MHOP)的同分异构体(例如,邻苯二甲酸单(7-羟基正辛基)酯)和邻苯二甲酸单氧辛酯(MOOP)的同分异构体(例如,邻苯二甲酸单(7-氧正辛基)酯)。DnOP代谢物的尿液排泄遵循双相排泄模式。尽管MCPP、MCHpP、MHOP和MOOP在4天后仍可检测到,但在DnOP给药的第一天后,代谢物水平显著降低。我们还研究了DnOP和MnOP在大鼠肝脏微粒体中的体外代谢。DnOP在体外产生MnOP、MHOP和PA,而MnOP在体外以可检测水平产生MHOP和PA。
The metabolism of di-n-octyl phthalate (DnOP) results in the hydrolysis of one ester linkage to produce mono-n-octyl phthalate (MnOP), which subsequently metabolizes to form oxidative metabolites. ... The toxicokinetics of DnOP in adult female Sprague-Dawley rats /was investigated/ by monitoring the excretion of DnOP metabolites in urine after oral administration of DnOP (300 mg/kg). By using authentic standards, the presence of urinary phthalic acid (PA), MnOP, and the major DnOP metabolite, mono-(3-carboxypropyl) phthalate (MCPP) was clearly established. Furthermore, ... five additional urinary DnOP oxidative metabolites /were identified/ based on their chromatographic behavior and mass spectrometric fragmentation pattern. These DnOP oxidative metabolites, are postulated to be mono-carboxymethyl phthalate (MCMP), mono-(5-carboxy-n-pentyl) phthalate (MCPeP), mono-(7-carboxy-n-heptyl) phthalate (MCHpP), and isomers of mono-hydroxy-n-octyl phthalate (MHOP) (e.g., mono-(7-hydroxy-n-octyl) phthalate) and of mono-oxo-n-octyl phthalate (MOOP) (e.g., mono-(7-oxo-n-octyl) phthalate). The urinary excretion of DnOP metabolites followed a biphasic excretion pattern. The metabolite levels decreased significantly after the first day of DnOP administration although MCPP, MCHpP, MHOP, and MOOP were detectable after 4 days. We also studied the in vitro metabolism of DnOP and MnOP by rat liver microsomes. DnOP produced MnOP, MHOP, and PA in vitro whereas, MnOP produced MHOP and PA in vitro at detectable levels.

代谢
邻苯二甲酸酯首先被水解为其单酯衍生物。一旦形成,单酯衍生物可以在体内进一步水解为邻苯二甲酸或与葡萄糖醛酸结合,这两种物质随后都可以被排出体外。单酯中的末端或倒数第二个碳原子也可以被氧化成醇,这种醇可以原样排出,或者首先被氧化成醛、酮或羧酸。单酯和氧化代谢物通过尿液和粪便排出体外。(A2884)
Phthalate esters are first hydrolyzed to their monoester derivative. Once formed, the monoester derivative can be further hydrolyzed in vivo to phthalic acid or conjugated to glucuronide, both of which can then be excreted. The terminal or next-to-last carbon atom in the monoester can also be oxidized to an alcohol, which can be excreted as is or first oxidized to an aldehyde, ketone, or carboxylic acid. The monoester and oxidative metabolites are excreted in the urine and faeces. (A2884)

  • 毒性总结
识别和使用:邻苯二甲酸二辛酯(DNOP)是一种无色、油性液体。它被用作增塑剂;DNOP可以占塑料和树脂总重量的5-60%。它存在于化妆品和着色剂中。DNOP还用作催化剂或引发剂的载体,以及电容器液的替代品。人类暴露和毒性:在173名疑似对塑料或胶水过敏原产生皮炎的患者中,有两名患者(占群体的1.2%)在用2.0% DNOP进行贴片测试后出现刺激反应。没有患者出现过敏反应。有一例研究报告了一名在制造人造皮革过程中持续暴露于DNOP的工人对该物质产生哮喘反应。在一项研究中,患有子宫内膜异位的女性在血液中的DNOP浓度显著高于49名患有子宫内膜异位的不孕女性(研究组),以及38名年龄匹配的无子宫内膜异位但与输卵管缺陷、纤维瘤、多囊卵巢、特发性不孕和经腹腔镜诊断的盆腔炎性疾病相关的不孕女性(对照组I)以及另外21名年龄匹配的女性(对照组II)。在主要暴露于邻苯二甲酸二丁酯的工人中报告了中毒性多发性神经炎的增加。也注意到了对邻苯二甲酸二辛酯、邻苯二甲酸二异辛酯、邻苯二甲酸苄基丁酯和三辛基磷酸酯较低水平的暴露。动物研究:据报道,DNOP在涂抹到豚鼠去毛皮肤上时会引起轻微的皮肤刺激。然而,DNOP在豚鼠中不是致敏剂。眼部给药DNOP导致轻微的结膜刺激,无角膜损伤。在啮齿类动物中进行的一些急性和中期限口服研究的结果表明,DNOP导致不良反应和发育效应的潜力较低。与其他邻苯二甲酸酯如DEHP不同,DNOP似乎不会影响睾丸功能或形态。在中期限研究中观察到的肝脏效应包括肝乙氧基resorufin-O-脱乙基酶活性统计学显著增加和肝脏结构的组织学变化。在这个浓度下也注意到了甲状腺毒性。将大鼠以100、300或600 mg/kg的DNOP通过腹腔注射给药,持续90天,评估免疫反应。高剂量导致甲状腺皮质和髓质早期区分消失,淋巴结滤泡数量减少,肾上腺形态丧失。然而,对免疫反应没有影响。在 Salmonella typhimurium TA98、TA100、TA1535和TA1537菌株(有和无S-9代谢激活系统)进行的研究结果表明,DNOP不是致突变剂。生态毒性研究:通过测量暴露于这些化合物对水蚤(Daphnia magna)繁殖力的影响以及对胖头 minnow(Pimephales promelas)早期生命阶段孵化成活的影响来评估DNOP的毒性。对于水蚤,暴露于1.0 mg/L DNOP会导致繁殖力显著降低。暴露于DNOP不会影响胖头 minnow早期胚胎或幼虫的存活,剂量高达10 mg/L(最高测试剂量)。在10 mg/L时,胚胎孵化显著降低,但在3.2 mg/L DNOP时没有影响。
IDENTIFICATION AND USE: Di-n-octylphthalate (DNOP) is a clear, oily liquid. It is used as a plasticizer; DNOP can represent 5-60% of the total weight of the plastics and resins. It is found in cosmetics and colorants. DNOP also serves as a carrier for catalysts or initiators and as a substitute for electrical capacitor fluid. HUMAN EXPOSURE AND TOXICITY: In 173 subjects with suspected dermatoses to plastic or glue allergens, two subjects (1.2% of the group) experienced irritation after patch testing with 2.0% DNOP. None of the patients had allergic reactions. There is a case study of a worker with continuous exposure to DNOP during the manufacture of imitation leather, who developed an asthmatic reaction to the substance. Women with endometriosis showed significantly higher concentrations of DNOP in their blood in a study of 49 infertile women with endometriosis (study group), and 38 age-matched women without endometriosis (control group I) but with infertility related to tubal defects, fibroids, polycystic ovaries, idiopathic infertility and pelvic inflammatory diseases diagnosed by laparoscopy and a further group of 21 age-matched women (control group II). An increase in toxic polyneuritis has been reported in workers exposed primarily to dibutyl phthalates. Lesser levels of exposure to dioctyl, diisooctyl, benzylbutyl phthalates, and tricresyl phosphate were also noted. ANIMAL STUDIES: DNOP was reported to be a slight skin irritant when applied to the depilated skin of guinea pigs. However, DNOP was not a skin sensitizer in guinea pigs. Ocular administration of DNOP resulted in slight conjunctival irritation and no corneal damage. The results of several acute- and intermediate-duration oral studies in rodents indicate that the potential of DNOP to cause adverse reproductive and developmental effects is low. Unlike other phthalate esters such as DEHP, DNOP does not appear to affect testicular function or morphology. Observed hepatic effects in intermediate duration studies consisted of a statistically significant increase in hepatic ethoxyresorufin-0-deethylase activity and histological changes in hepatic architecture. Thyroid toxicity was also noted at this concentration. Rats treated with 100, 300, or 600 mg/kg DNOP by ip injection for up to 90 day were evaluated for immunological responses. The high dose resulted in early loss of distinction between the cortex and medulla of the thyroid, reduced numbers of follicles in the lymph nodes, and loss of morphology in the adrenal glands. However, there was no effect on immune response. Results of studies in Salmonella typhimurium strains TA98, TA100, TA1535, and TA1537 (with and without S-9 metabolic activation systems) indicated that DNOP is not mutagenic. ECOTOXICITY STUDIES: The toxicity of DNOP was assessed by measuring the effect of exposure to these compounds on the fecundity of Daphnia magna and on the hatching and survival of the early life stages of the fathead minnow Pimephales promelas. For Daphnia magna, exposure to 1.0 mg/L DNOP caused a significant reduction in reproduction. Exposure to DNOP did not affect survival of either early embryos or larvae of the fathead minnow at doses up to 10 mg/L (the highest dose tested). Hatching of the embryos was significantly decreased at 10 mg/L, but not at 3.2 mg/L DNOP.

  • 毒性总结
邻苯二甲酸酯类是内分泌干扰物。它们会降低胎儿睾丸的睾酮生产,并通过降低mRNA表达来减少类固醇生成基因的表达。一些邻苯二甲酸酯还被证明可以减少胰岛素样肽3(insl3)的表达,这是一种由莱迪希细胞分泌的重要激素,对尿囊带的发展至关重要。动物研究显示,这些效应会干扰生殖发育,并可能导致受影响的幼体出现多种畸形。(A2883)
Phthalate esters are endocrine disruptors. They decrease foetal testis testosterone production and reduce the expression of steroidogenic genes by decreasing mRNA expression. Some phthalates have also been shown to reduce the expression of insulin-like peptide 3 (insl3), an important hormone secreted by the Leydig cell necessary for development of the gubernacular ligament. Animal studies have shown that these effects disrupt reproductive development and can cause a number of malformations in affected young. (A2883)

制备方法与用途

邻苯二甲酸二辛酯概述

邻苯二甲酸二辛酯是一种无色或淡黄色的透明液体,具有特殊的气味。其沸点为386℃,相对密度在20/4℃时约为0.980~0.983。该物质不溶于水,但能溶解于乙醇、乙醚等有机溶剂中。它由邻苯二甲酸酐与2-乙基己醇通过酯化反应制得。作为塑料加工中最常用的增塑剂之一,其综合性能优越,增速效率高,挥发性小,并具有良好的耐紫外光和耐寒性能,使制品的柔软性和电性能都得到了改善。此外,它的毒性较小,半致死量大于30克/公斤体重。法国癌研究所的研究证实,即使饲料中含量为0.05%,长期喂养四代大白鼠也未发现其有毒或致癌。

化学性质

邻苯二甲酸二辛酯是一种淡黄色油状液体,凝固点为-55℃,沸点在231℃(0.67千帕)时。它的相对密度为25/4℃时的0.9861,折光率为1.483(25℃)。该物质能与多数有机溶剂混溶,但不溶于水。

用途

邻苯二甲酸二辛酯可以与聚氯乙烯、氯乙烯-乙酸乙烯共聚物、聚乙烯醇缩丁醛、乙酸丁酸纤维素、硝酸纤维素、乙基纤维素、聚甲基丙烯酸甲酯和聚苯乙烯等树脂相容,但与乙酸纤维素、聚乙酸乙烯酯不相容。它的增塑效率与DOP相同,但在耐寒性、耐候性和耐挥发性以及对增塑糊粘度的稳定性方面表现更佳,电绝缘性能略逊于DOP。虽然价格较高,但它仍广泛应用于食品包装材料和溶剂等领域。

此外,邻苯二甲酸二辛酯还用作气相色谱固定液,用于选择性保留和分离芳香族化合物、不饱和化合物以及各种含氧化合物(如醇、醛、酮、酯等)。它也被用作增塑剂。

生产方法

该物质由苯酐与正辛醇通过酯化反应制得。所需比例为每吨苯酐需390公斤正辛醇,每吨正辛醇需690公斤苯酐。

物理化学性质

邻苯二甲酸二辛酯被归类为易燃液体,并且毒性较低。急性毒性实验显示,大鼠口服的半致死量为47,000毫克/公斤体重;小鼠为6513毫克/公斤体重。皮肤接触兔子24小时后表现为轻度刺激;眼睛接触同样表现出轻度刺激。

安全与储存

该物质属于易燃液体,遇到明火、高温或强氧化剂容易燃烧,并释放出刺激性烟雾。在存储和运输过程中需要确保包装完好无损,轻拿轻放,远离明火和高温环境,并与其他氧化剂分开存放。灭火时可使用泡沫、二氧化碳或干粉灭火器。
