Process for preparing a dialkyl acetal of a C8 to C30 aldehyde

摘要

Improved water resistant acetal sizing agents including 1,1-octadecoxyoctadecane are provided along with methods for their synthesis including methods in which C8 to C30 alkyl bromides are reacted with a polyol under basic conditions and those in which a C8 to C30 primary alcohol is reacted with an organic base in the presence of a suitable oxidizing agent under basic conditions.
