Abstract

The peculiarities of the condensation reaction of cyclopentanone and its C-3-C-7 alkyl derivatives with propantriol using the catalyst on the basis of natural perlite modified by iron, zinc and zirconium salts have been investigated. It has been established that a yield and composition of products depend on both of nature of catalyst and on temperature and tests duration. It has been experimentally established that the high yields of spiroacetals have been prepared at modification of the natural perlite by zirconium salts. It has been shown that with increase of a quantity of zirconium applied on natural perlite from 0.1 to 3.5% a yield of purposeful product is increased and reaches 76.4%. For selective carrying out of the condensation reaction of cyclopentanone and its C-3-C-7 alkyl derivatives with propantriol as azeotrope-forming solvent it is advisable to use toluene and m-xylene
