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. |

A process is described for the preparation of isobutene by dehydroisomerisation of n-butane comprising feeding a gaseous mixture of n-butane and hydrogen, preferably diluted with an inert gas, into a fixed catalytic bed consisting of a first supported catalyst a and a second supported catalyst b, where the said catalyst a is formed of a solid and granular support of porous gamma-alumina on the surface of which are deposited catalytic amounts of platinum and optionally also one or more promoters and the said catalyst b is formed of Boralite B; the said catalysts a and b being homogeneously distributed in the catalytic bed, or being arranged in the form of two contiguous layers. |
