161 METHOD FOR DECREASING THE CONTENT OF BUTYLPHENYL KETONE IN PHENYLBUTYL CARBINOL SK50898 1998-04-20 SK50898A3 1999-11-08 GOMORY JURAJ; KARABINOS JOZEF; KOLLAR MIROSLAV; SPEVAR FERDINAND
Reducing of butyl phenyl ketone in phenyl butyl carbinol by effect of the mixture of phenyl butyl carbinol, methanol and diethylether with sodium boron hydride under the temperature of reflux of the mixture during 1 hour, followed by cooling of the reaction mixture, adding the water and distillation ether and phenyl butyl carbinol off. The method can be used in industrial production and processing of phenyl butyl carbinol substance, which is used in human medicine as choleretic.
