Interactions · 2 件

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 件

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.

調製方法 · 2 件

2-Chloroethanol is manufactured by the reaction of ethylene gas with dilute hydrochlorous acid. The principal use of 2-chloroethanol was formerly in producing ethylene oxide, in which ethylene was reacted with hypochlorous acid. However, the current production of ethylene oxide does not use this procedure. Facilities for ethylene chlorohydrin have, in many cases, been converted to the production of propylene chlorohydrin, the dehydrochlorination of which yields propylene oxide.

純化方法Dry it with, then distil it from, CaSO4 in the presence of a little Na2CO3 to remove traces of acid. [Beilstein 1 IV 1372.]
