Reaction Steps

A 500 ml four-necked flask was charged with a 70 wt % aqueous solution of 143 g (0.55 mole) of D-sorbitol, 73.7 g (0.55 mole) of 3,4-dimethylbenzaldehyde and 12 g of 50 wt % sulfuric acid. The air inside the system was replaced with nitrogen gas. The contents of the flask were stirred at a temperature of 21° C. for 6 hours. The obtained reaction mixture was analyzed by GC. It was found that mono(3,4-dimethylbenzylidene)-D-sorbitol was produced in a yield of 70% and 0.5% or less of bis(3,4-dimethylbenzylidene)-D-sorbitol was also produced.
