Condensation And Polymerization Of Some Lower Aldehydes And The Influence Of Acid And Basic Groups Of The Catalyst On The Reaction Rate

Аннотация

Acidic or basic catalytic systems, as well as zeolite-type catalysts are used for condensation and polymerization reactions of ethyl and unsaturated carbonyl compounds. Reactions involving lower aldehydes, as a rule, are carried out in the gas-phase variant and have rather low selectivity and conversion of reagents. This problem is partially solved by recirculation of unreacted reagents. The most promising way to solve the problem of selectivity and activity is selective carrying out of the reaction under conditions of homogeneous catalysis with varying acid-base properties of the catalyst and reaction medium.
