Abstract
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.

A method of preparing a dialkyl acetal of a C8 to C30 aldehyde comprising the steps of:
- (a) reacting a carbohydrate with a base, in alcohol, to produce a caustic treated polyol;
- and (b) reacting a C8 to C30 alkyl bromide in the presence of the caustic treated polyol of step (a) and a suitable solvent to produce said distearyl acetal.
A method of preparing a dialkyl acetal of a C8 to C30 aldehyde comprising the step of reacting a C8 to C30 primary alcohol with an organic base in the presence of a suitable oxidizing agent.
