Abstract
The present invention relates to a two-stage liquid phase process wherein an alk-2-enyl glycidyl ether having the formula ##STR1## wherein R is hydrogen or lower alkyl; R' is C.sub.2 to C.sub.4 alkylene; n has a value of from 1 to 4 and n' has a value of from 0 to 4, is catalytically isomerized to the corresponding alk-1-enyl glycidyl ether in the first-stage of the reaction and the reaction mixture of the first-stage, containing the isomerization catalyst is then contacted with carbon dioxide in the presence of a phase transfer catalyst under a pressure ranging from atmospheric to about 400 psig in the second stage of the reaction.
