【Abstract】 Diacetals of pentaerythritol were prepared by condensation of aldehydes with pentaerythriol in benzene with 12 tungstophosphoric acid as catalyst. The conditions of preparation have been pointed. The products were characterized by 1H NMR, IR and elemental analysis. The catalyst can be recovered conveniently.更多还原
