Procedure

A powdery reaction mixture is obtained in the same manner as in Example 8 with the exception of using 24.0 g of xylitol, 41.5 g of p-chlorobenzaldehyde, 0.5 g of 50% sulfuric acid, 60 ml of trichloroethylene and 18 ml of dioxane. The mixture is similarly after-treated, affording di-(p-chlorobenzylidene)xylitol in a yield of 92% with a purity of 97%.
