Abstract
A NEW PROCEDURE FOR THE OBTAINING OF SORBIC ACID FROM CETHANE AND CROTONIC ALDEHYDE, characterized in that a small amount of a zinc salt of an organic acid with at most three carbon atoms is used as the catalyst, and the highlight product (polyester), which still contains a catalyst, is heated with concentrated mineral acids up to temperatures of 50-100º C, preferably 70-80º C.
