Interactions · 2 条

Simultaneous administration of ethyl alcohol increased the LD50 of ethylene chlorohydrin regardless of the route of administration (peroral or percutaneous). Necrotic lesions produced in the liver and kidney by ethylene chlorohydrin were also reduced in number and extent by ethanol. Blood concn of the chlorohydrin were raised by ethanol administration, which suggests that the protective effect is due to competitive inhibition of chlorohydrin metabolism to chloroacetaldehyde.

2-Chloroethanol is thought to interfere with the detoxification mechanisms of the alkaloids. Chickens were administered monocrotaline after separate groups were pretreated with BHA and 2-chloroethanol. There was an apparent deleterious effect of monocrotaline in 2-chloroethanol-pretreated chickens, similar to that in non-pretreated birds, with respect to growth rates, morbility, mortality, and hepatic histopatholoqy. Monocrotaline pyrrole formation was measured in chickens pretread with BHA and 2-chloroethanol by means of the Erlich reagent reaction spectrophotometric assay. There was a significant difference in pyrrole production between the treatment groups. The 2-chloroethanol plus-monocrotaline (40 mg/kg), BHA (500 mg/kg) plus monocrotaline, nonocrotaline, BHA (100 mg/kg) plus monocrotaline (20 mg/kg), and BHA (500 mg/kg) plus 2-chloroethanol and monocrotaline groups had decreasing amounts of pyrrole metabolite formation respectively.

Environmental Fate · 3 条

TERRESTRIAL FATE: If released on soil 2-chloroethanol would be expected to leach because of its estimated very low adsorptivity to soil. In view of its low estimated Henry's Law constant, 1.04X10-7 atm-cu m/mole(1), and low estimated adsortivity to soil, 2-chloroethanol would not be expected to volatilize from moist soil. However, it would be expected to volatilize from dry soil and other surfaces because it's vapor pressure is appreciable, 7.18 mm Hg at 25 °C(2). 2-Chloroethanol was readily biodegradable in screening tests and biological treatment simulations tests which suggest that it may biodegrade in soil(SRC).

AQUATIC FATE: If released in water, the fate of 2-chloroethanol is not clear. In view of its low estimated Henry's Law constant, 1.04X10-7 atm-cu m/mole(1), 2-chloroethanol would not be expected to volatilize from surface waters. It would not be expected to adsorb to sediment, bioconcentrate in fish, photolyze or hydrolyze. However, based on data from screening tests, it may biodegrade(SRC).

ATMOSPHERIC FATE: 2-Chloroethanol reacts with photochemically-produced hydroxyl radicals in the atmosphere and has a rate constant of 1.40X10-12 cu cm/molec-sec(1) for this reaction. Assuming a hydroxyl radical concn of 5X10+5 per cu cm, the half-life of 2-chloroethanol in the atmosphere will be 11.5 days(SRC). 2-Chloroethanol is soluble in water(2) and would be subject to washout by rain.

2-CHLOROETHANOL WAS GIVEN ORALLY TO RATS. LIVER GLUTATHIONE WAS RAPIDLY DEPLETED & S-CARBOXYMETHYLGLUTATHIONE WAS FORMED. TOXICITY OF 2-CHLOROETHANOL IS PROBABLY DUE TO ITS CONVERSION TO CHLOROACETALDEHYDE IN VIVO.

2-chloroethanol was detected in the blood and liver of rats during the first 24 days after oral dosing of CH2ClCH2Cl /ethylene dichloride/ at 750 mg/kg.

Disposition and metabolism of 1-(2-chloroethyl)-3-(2',3',4'-tri-O-acetylribopyranosyl)-1-nitrosourea (RPCNU) were studied in rats after labeling RPCNU with (14)C- in 3 different positions. Within the first min after injection, most of the radioactivity derived from ethyl-(14)C groups was recovered as volatile products. Among these, 2-chlorothanol was identified as a main component.

The excretion & tissue distribution of (14)C-labeled chloroethanol were studied in rats following single oral admin of 5 & 50 mg/kg. At both dose levels, the radioactivity was rapidly eliminated, mainly in the urine. On the first day 77.2% of the dose was found in the urine, 1.7% in the feces, and 1.0% as CO2 in the expired air. Only 2.8% was excreted by these routes during the following 3 days. The residual radioactivity after 4 days was almost equally distributed. Approx 0.4% of the dose was in the liver and 3% in the whole organism.

用途氯乙醇是重要的有机溶剂和有机合成原料。以前氯乙醇的最大用途是生产环氧乙烷,现在绝大部分氯醇法环氧乙烷装置已被直接氧化法所取代。现在氯乙醇的主要用途是作聚硫橡胶的原料以及染料、农药、医药的中间体。氯乙醇与硫化钠反应可得硫代二甘醇,是纺织品的印染溶剂,亦是还原染料,聚亚基二氯的增塑剂。氯乙醇衍生物β,β'二氯二乙基醚的是合成芥子气毒气的原料,亦是精制润滑油的萃取溶剂,也用作土壤杀菌剂。氯乙醇可合成二氯乙基缩甲醛,是生产聚硫弹性体的原料之一。氯乙醇与乙炔反应可生成氯乙基乙烯基醚,是生成聚丙烯酸性体的原料。氯乙醇用60%硝酸氧化能以90%收率生成氯乙酸,用于合成染料、氨基乙酸、丙二酸酯,羟基乙酸、肾上腺素、2,4-二氯苯氧基乙酸、乐果、羧甲基纤维素、费洛那尔安眠药、氯乙酰胺、碘乙酰胺、N-甲基氨基乙酸钠。在医药工业中,氯乙醇用于磷酸哌嗪、呋喃唑酮、四咪唑、驱蛔灵和普鲁卡因等的生产,在农药生产中用作杀虫剂1059的原料。由氯乙醇经氨化、氯化可得2-氯乙胺盐酸盐([870-24-6],Beil.4,133),这是一种药物中间体,用于制造驱虫净。

用途用于制造环氧乙烷、合成橡胶、染料、医药及农药等,也是有机溶剂

用途用作溶剂、杀虫剂及甘蔗催芽剂等,也用于农药和染料合成

制备方法

生产方法氯乙醇有多种制备方法。环氧乙烷与盐酸反应,是实验室制备氯乙醇的最方便方法。实际上,乙二醇与二氯化硫反应得到氯乙醇,也是实验室制备氯乙醇的方法之一。如果环氧乙烷与无水氯化氢在氯化铁和磷酸二氢钠存在下反应,则无副产乙二醇生成,适用于制造高纯度氯乙醇。氯乙醇的工业生产方法基本上还是1991年Gomberg提出的方法,将乙烯和氯同时通入水中,氯与水反应生成次氯酸,次氯酸与乙烯加成即得氯乙醇。
