Regularities in the catalytic de hydrogenation of primary and secondary alcohols

Abstract

1. It has been established that primary alcohols with straight chains from C2 to C9 are dehydrogenated on an oxide catalyst with velocities which are close to each other and that the velocity of the dehydrogenation of secondary alcohols decreases with an increased molecular weight. The velocity of dehydrogenation of alcohols with a branched structure was found to be greater than that of alcohols with a straight-chain structure. 2. It has been found that there is a parallelism between the energy of activation, the pre-exponential factor logarithm, and increments of the heat content and entropy connected with the adsorption displacement of alcohols by the corresponding aldehydes and ketones from the active dehydrogenation centers of the catalyst.
