Abstract
A new method for the preparation of acetals of long chain fatty aliphatic aldehydes and polyols containing four or more hydroxyl groups which produces the acetals in a relatively pure form by reaction in a mutual solvent, preferably a C.sub.1 to C.sub.4 fatty carboxylic acid. The `clean` acetals are useful emulsifying agents and their esters and polyalkoxy substituents are useful dispersants and surfactants for aqueous compositions.
Claims4
An acetal having a color not exceeding 250 Hazen units derived from a polyol containing at least four hydroxyl groups and a fatty aliphatic aldehyde having an alkyl chain containing at least 11 and up to 20 carbon atoms.
