Our systematic study employing chlorobenzene, chloroform, dichloromethane, and toluene as primary solvents, as well as H 2 O and amylene as secondary solvents, confirms that the main factors for the generation of pinholes in HTLs are (1) the presence of a secondary solvent in the primary solvent and (2) considerable miscibility variations Cited by: 6. To produce ethylene chlorohydrin by a continuous process, ethylene is passed under a pressure of atm at C in to a tower. A solution of hydrated lime is then charged in to the tower, so that under the stated temperature and pressure about 28 g of ethylene per lit. of alkali results.

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.

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.
