标 题 :Synthesis of d-2-amino-1-butanol
发明人:SINGH BALWANT
权利人:AMERICAN CYANAMID CO
摘要:D-2-Amino-1-butanol, for the synthesis of ethambutol hydrochloride, d,d'-2,2'-(ethylenediimino)di-1-butanol dihydrochloride, is produced in high purity and good yields by the reaction of butene-1, a nitrile, preferably an excess of acetonitrile, and chlorine to form N-[1-(chloromethyl)propyl]acetimidoyl chloride which is hydrolyzed to dl-2-amino-1-butanol, which can be isolated as the hydrochloride, or free base, or a mixture, resolved with L(+)- tartaric acid and the d-2-amino-1-butanol reacted with ethylene dichloride and then hydrochloric acid to form ethambutol hydrochloride. A minimum of by-products which are conveniently split out permits the economical synthesis of a pharmaceutical grade product.

标题:Removal of free radical inhibitors to promote synthesis of alpha, omega-dichloroalkane telomers from ethylene and sulfuryl chloride
发明人:HUDSON JR JOSEPH A
权利人:CONTINENTAL OIL CO
摘要:In the synthesis of alpha,omega-dichloroalkanes such as 1,2dichlorobutane and 1,6-dichlorohexane from ethylene and sulfuryl chloride, yield is improved when the reaction environment is scrupulously rendered and maintained free from Lewis acids and other free radical inhibiting materials.

标题 :Preparation of p-fuchsones and synthesis of p-dihydroxylated aromatic compounds therefrom
发明人:COSTANTINI MICHEL; MANAUT DANIEL; MICHELET DANIEL
权利人:RHONE POULENC CHIMIE
摘要:p-Dihydroxylated aromatic compounds are prepared via the oxidation of p-fuchsones, the latter advantageously being synthesized by reacting a phenolic compound having at least one hydrogen atom in the para-position to the hydroxyl function with a non-enolizable ketonic compound, in the presence of a catalytically effective amount of an acid catalyst and, optionally, a cocatalytically effective amount of an ionizable sulfur-containing compound.
