Suitable catalysts include sodium hydroxide, potassium hydroxide, tertiary amines, potassium carbonate, sodium acetate, boron triflouride, and acid clays. Further addition of propylene oxide yields the di-, tri-, andFile Size: KB.
3-Monochloro-1,2-propanediol is mutagenic in vitro, but the limited available data in vivo showed negative results. Most of the target tissues of cancer in experimental animals were not tested for genetic effects in vivo. 3-Monochloro-1,2-propanediol exhibits nephrotoxicity, immunotoxicity, neurotoxicity, and testicular toxicity in rodents. Preparation of (S)chlorooctanol and (S)bromooctanol was carried out by the enzymatic hydrolysis of halohydrin palmitates using biocatalysts. Halohydrin palmitates were prepared by various methods from palmitic acid and 1,2-octanediol. A tandem hydrolysis was carried out using lipases from Candida antarctica (Novozym® ), Rhizomucor miehei Cited by: 7.

Treatment of the crude epoxides with aqueous hydrochloric acid gave crystalline (2S,3S)-N,N-dibenzylamino chlorohydrin hydrochlorides in 32−56% overall yield and high isomeric purity.
These compounds are versatile synthetic intermediates for the preparation of hydroxyethylamine-based HIV protease inhibitors, either directly as such, or via conversion to the corresponding N-Boc-(2S,3S)-aminoalkyl Cited by: Room reservation.

The method comprises the following steps: 1) adding phenol and an oxidizing agent into a reaction vessel, feeding protective gas, namely, nitrogen, and heating to be DEG C; 2) feeding ethylene oxide gas, and enabling reaction at the temperature of Author: 聂超. 3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH 2 CH(OH)CH 2 Cl.
It is a colorless liquid. It is a versatile multifunctional building block. The compound has attracted attention as the most common member of chemical food contaminants known as chloropropanols. It is suspected to be Appearance: Viscous, colorless liquid. 2-Chloroethanol was once produced on a large scale as a precursor to ethylene oxide: This application has been supplanted by the more economic direct oxidation of ethylene.
Otherwise chloroethanol is still used in a number of specialized applications. Several dyes are prepared by the alkylation of aniline derivatives with ein Reference: Abstract: The ethylene oxide hydration process in a catalytic fixed bed tube reactor was studied.

The best report is that of Ballinger and Long10 on the dehydrochlorination of 2-chloroethanol 1 which also summarizes some early studies.
They proved that the reaction between 1 and sodium hydroxide is a specific hydroxide.
