      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.
