実験手順
The reaction procedure of Example 8 is repeated in the same manner with the exception of using 26.8 g of sorbitol, 48.0 g of p-isopropylbenzaldehyde, 1.0 g of C9 alkylbenzenesulfonic acid, 9 ml of dimethylsulfoxide, 120 ml of benzene and 100 ml of isopropanol. The reaction is conducted in a semisolid phase for 3 hours, giving di-(p-isopropylbenzylidene)sorbitol in a yield of 93% with a purity of 95%.
