Abstract

1460869 Preparation of acetals E I DU PONT DE NEMOURS & CO 31 July 1975 [31 July 1974 7 Aug 1974] 32120/75 Heading C2C A process for the preparation of liquid acetals having a misoibility with water at 25‹ C. of less than 10% by weight comprises reacting at least one alcohol containing 4 or more carbon atoms with an at least molar equivalent amount of at least one aldehyde in the presence of an acid catalyst at a temperature from 0‹ to 100‹ C.
