识别和使用:2-丁烯是一种无色气体。它被用作溶剂和交联剂。它还用于聚合汽油,以及用于丁二烯的合成,还用于衍生物的合成。人体研究:2-丁烯是一种窒息性气体。液态2-丁烯的快速蒸发可能导致冻伤。它可能对中枢神经系统产生影响。暴露可能导致失去意识。动物研究:大鼠在2-丁烯的名义浓度为10,000 ppm(22,948 mg/立方米)的环境中暴露了4小时。没有观察到临床体征,在14天的观察期内正常生长。2-丁烯在狗身上是一种心脏致敏剂。在大鼠的发展研究中,与对照组相比,在交配行为、生育能力和妊娠指数、植入点数量和每个母体黄体数量、出生的幼崽数量、出生前后幼崽的存活率以及幼崽性别比方面没有影响。对幼崽的发展没有处理相关的影响。雌雄大鼠在配种前两周以2500或5000 ppm(5737或11,474 mg/立方米)的目标浓度暴露于2-丁烯,在配种期间(1周)直至妊娠第19天(暴露39-46天)。无论雌雄,或怀孕雌性大鼠,都没有发生显著的系统毒性。2-丁烯是一种中枢神经系统抑制剂。大约13至13.5%(300或400 mg/L)会导致深度中枢神经系统抑制,而在小鼠中大约19%(120至420 mg/L)是致命的。它是一种轻微的粘膜刺激剂。对2-丁烯在大鼠淋巴细胞中进行了一次染色体畸变研究。无论是在代谢激活的存在还是缺失中,染色体畸变的频率都没有显著增加。2-丁烯对S. typhimurium TA98, TA100, TA1535, TA 1537和E.coli WP2uvrA,无论是否代谢激活,都没有诱变性。
IDENTIFICATION AND USE: 2-Butene is a colorless gas. It is used as a solvent and a cross-linking agent. It is also used to polymerize gasoline, and for butadiene synthesis, as well as the synthesis of derivatives. HUMAN STUDIES: 2-Butene is an asphyxiant gas. Rapid evaporation of liquid 2-butene may cause frostbite. it may cause effects on the CNS. Exposure may result in unconsciousness. ANIMAL STUDIES: Rats were exposed for 4 hr to 2-butene at a nominal concentration of 10,000 ppm (22,948 mg/cu m). No clinical signs were seen and normal growth occurred over the 14 d observation period. 2-Butene is a cardiac sensitizer in dogs. In developmental studies in rats, there were no effects on mating behavior, fertility and gestation indices, the number of implantation sites and corpora lutea per dam, numbers of pups delivered, viability of pups at and after birth and the pup sex ratio when compared to the control group. There were no treatment-related effects on the development of pups. Male and female rats were exposed to 2-butene at target concentrations of 2500 or 5000 ppm (5737 or 11,474 mg/cu m) for two weeks prior to breeding, during breeding (1 week) and until day 19 of gestation (39-46 days of exposure). No significant systemic toxicity occurred in either sex, or in pregnant female rats. 2-Butene is a CNS depressant. About 13 to 13.5% (300 or 400 mg/L) causes deep CNS depression, and in mice about 19% (120 to 420 mg/L) is fatal. It is a mild mucous membrane irritant. A chromosome aberration study was conducted with 2-butene in rat lymphocytes in vito. No significant increases were seen in the frequency of chromosome aberrations either in the presence or absence of a metabolic activation. 2-Butene was not mutagenic to S. typhimurium TA98, TA100, TA1535, TA 1537 and E.coli WP2uvrA, with or without metabolic activation.

    bismuth(III) halides (BiX3; X=Cl, Br and I) towards a series of alcohols has been investigated. Three different reactions have been studied, namely: halogenation, dehydration and etherification. The behaviour of these bismuth derivatives was found to depend on the nature of the halide bonded to the bismuth atom. Their reactivities can be interpreted on the basis of the Hard and Soft Acids and Bases
