代谢
1,2-二-1,1,2-三氟乙烷(HCFC-123a)是替代消耗臭氧烃的一种潜在选择。研究了HCFC-123a在大鼠、小鼠和人体微粒体中的代谢,以及在大鼠和小鼠体内的代谢。大鼠、小鼠和人体肝脏微粒体将HCFC-123a代谢为无机化物和二氟乙酸化物形成依赖于时间、NADPH、HCFC-123a和蛋白浓度。未处理大鼠的微粒体以较低速率(0.49 nmol化物/20分钟x毫克蛋白)氧化HCFC-123a。用吡啶乙醇(P450 2E1的诱导剂)预处理大鼠,增加了化物释放的速率。在小鼠肝脏微粒体中,HCFC-123a氧化释放化物的速率显著高于大鼠肝脏微粒体(1.68 nmol化物/20分钟x毫克)。将HCFC-123a与微粒体和二乙基氨基甲酸酯(100微M,P450 2E1的抑制剂)一起孵化,化物形成减少了60%以上。在不同样本的人体肝脏微粒体中,化物形成的速率是未处理大鼠肝脏微粒体中观察到的速率的两倍到四倍。在大鼠和小鼠暴露于封闭循环暴露系统中的HCFC-123a浓度高达5000 ppm时,尿中代谢物中发现了二氟乙酸和无机化物。在大鼠暴露于2000 ppm以上的HCFC-123a 6小时后,HCFC-123a的生物转化达到饱和,而在小鼠暴露于高达5000 ppm的浓度时,没有出现饱和现象。获得的结果表明P450 2E1在HCFC-123a的氧化和HCFC-123a在啮齿动物中的不同氧化生物转化能力中发挥重要作用。因此,在给予高剂量后,小鼠可能对HCFC-123a的毒性作用更敏感。
1,2-Dichloro-1,1,2-trifluoroethane (HCFC-123a) is a potential alternative to replace ozone-depleting chlorofluorocarbons. The metabolism of HCFC-123a was studied in microsomes of rats, mice, and humans as well as in rats and mice in vivo. Rat, mouse, and human liver microsomes metabolized HCFC-123a to inorganic fluoride and chlorodifluoroacetic acid. Fluoride formation was dependent on time and NADPH, HCFC-123a, and protein concentration. Microsomes from untreated rats oxidized HCFC-123a at low rates (0.49 nmol fluoride/20 min x mg protein). Pretreatment of rats with pyridine and ethanol, inducers of P450 2E1, increased the rates of fluoride release. In mouse liver microsomes, the rates of HCFC-123a oxidation to release fluoride were significantly higher (1.68 nmol fluoride/20 min x mg) than in rat liver microsomes. Incubation of HCFC-123a with microsomes and diethyldithiocarbamate (100 microM), an inhibitor of P450 2E1, reduced fluoride formation by more than 60%. In different samples of human liver microsomes, rates of fluoride formation were between two- and fourfold higher than those observed in liver microsomes from untreated rats. In rats and mice exposed to concentrations of HCFC-123a up to 5000 ppm in a closed recirculating exposure system, chlorodifluoroacetic acid, and inorganic fluoride were identified as urinary metabolites. The biotransformation of HCFC-123a in rats was saturated after exposure to more than 2000 ppm HCFC-123a for 6 hr, whereas no saturation was evident in mice exposed to concentrations of up to 5000 ppm. The obtained results suggest a major role of P450 2E1 in the oxidation of HCFC-123a and in the different capacities for oxidative biotransformation of HCFC-123a in rodents. Mice may thus be more sensitive to toxic effects of HCFC-123a depending on biotransformation after administration of high doses.

吸入利昂的受害者需要针对缺氧、中枢神经系统麻醉和心脏症状进行管理。必须将患者从暴露环境中移出,并使用高流量补充氧气。应评估呼吸系统是否有损伤、吸入性肺炎或肺肿,并适当治疗。中枢神经系统发现的问题应支持性治疗。保持一个平静的环境,避免身体劳累,以防止内源性肾上腺素平升高是至关重要的。不得使用外源性肾上腺素药物,以避免诱发敏感的心肌心律失常。阿托品在治疗心动过缓方面无效。对于室性心律失常,二苯基海因和电击可能有效。对于低温引起的皮肤损伤,应通过40-42°C的浴复温,直到血管扩张冲洗恢复。应抬高患肢,并使用晚期的外科清创标准冻伤管理。眼部暴露需要冲洗和裂隙灯评估损伤。/利昂/
Victims of freon inhalation require management for hypoxic, CNS anesthetic, & cardiac symptoms. Patients must be removed from the exposure environment, & high flow supplemental oxygen should be utilized. The respiratory system should be evaluated for injury, aspiration, or pulmonary edema & treated appropriately. CNS findings should be treated supportively. A calm environment with no physical exertion is imperative to avoid increasing endogenous adrenegic levels. Exogenous adrenergic drugs must not be used to avoid inducing sensitized myocardial dysrhythmias. Atropine is ineffective in treating bradyarrhythmias. For ventricular dysrhythmias, diphenylhydantoin & countershock may be effective. Cryogenic dermal injuries should be treated by water bath rewarming at 40-42 °C until vasodilatory flush has returned. Elevation of the limb & standard frostbite management with late surgical debridement should be utilized. Ocular exposure requires irrigation & slit lamp evaluation for injury. /Freons/

  • Deuterium isotope studies of the hydrofluorination of chloroethenes over chromia catalysts
    作者:David M.C. Kavanagh、T.Anthony Ryan、Brynmor Mile

    日期:1993.9
    The mechanism of the catalytic fluorination of chloroalkenes over a chromia catalyst hasbeen investigated by examining the effects of substituting DF for HF as the fluorinesource for reaction with tetrachloroethene and trichloroethene. At a temperature of 250°C and a HF(DF)/alkene molar ratio of 4.2:1, the rate of conversion of tetrachloroetheneis increased by using DF and there is a concomitant increase
    通过研究用DF代替HF代替HF作为源与四氯乙烯三氯乙烯反应的效果,研究了氧化铬催化剂上代烯烃催化化的机理。在250°C的温度和HF(DF)/烯烃的摩尔比为4.2:1的情况下,使用DF可以提高四氯乙烯的转化率,同时对某些烷烃的选择性也随之增加,而对氟烷的选择性则随之降低。烯烃。对于卤代烯烃和烷烃观察到的相反行为表明,烯烃不是通过一系列氢化和脱氯化氢反应生产烷烃的重要中间体。对于四氯乙烯烷烃的主要反应途径是在重度化的氧化铬表面上直接进行/交换,而中间体的CH/CD裂解极少。与二氯乙烯氧化铬催化剂上反应后,用DF代替HF不会引起产物选择性的变化。但是,双狄特罗和单狄特罗产品的存在表明,对于较少取代的烯烃,/交换和HF加成/ HCl消除途径都在发生。

  • Selective Reduction of Halopolyfluorocarbons by Organosilicon Hydrides
    作者:Viacheslav A. Petrov
    DOI:10.1021/jo9807363
    日期:1998.10.1
    It is demonstrated that silicon hydrides can be used for reduction of polyfluorinated halocarbons. For example, the reaction between CF(3)CCl(2)F and excess triethylsilane, catalyzed by benzoyl peroxide, leads to the formation of a mixture containing CF(3)CHClF (major), CF(3)CH(2)F, and ClSi(C(2)H(5))(3). On the other hand, the reaction of chlorofluoroalkanes, containing an internal -CCl(2)- group
    已证明氢化硅可用于还原多化卤代烃。例如,CF(3)CCl(2)F和过量的三乙基硅烷之间的反应(由过氧化苯甲酰催化)导致形成包含CF(3)CHClF(主要),CF(3)CH(2)F的混合物,和ClSi(C(2)H(5))(3)。另一方面,包含内部-CCl(2)-基团的烷烃的反应很容易同时还原两个,从而导致化合物如(CF(3))(2)CH(2)和CF(3) CH(2)C(2)F(5)。与烷烃相比,烷烃具有更高的反应活性,在没有催化剂的情况下,与氢硅烷的反应迅速进行,且温度较高。
