Abstract:
This invention is directed to a process for preparation of acetal derivatives, 1,3:2,4-bis(3,4-dimethylbenzylidene)sorbitol (DMDBS) and 1,3:2,4-bis(4-methylbenzylidene)sorbitol (MDBS) by carrying out a dehydrocondensation reaction between an aldehyde and an alditol using an aqueous ionic fluid as the acid catalyst.
