Abstract
An acetal compound may be formed by the method of reacting a substitiuted or unsubstituted benzaldehyde, a polyhydric alcohol, and an at least one acid catalyst at ambient temperatures, in a homogenous reaction media in the presence of at least one water miscible organic solvent. The molar ratio of the acid catalyst to the benzaldehyde may be less than about 0.6 to 1, respectively, of acid catalyst to benzaldehyde.
Claims23
