Procedure
Using the method of Example 21, 42 g 4-chlorobenzaldehyde, 27.6 g glycerol and 4 ml 40 percent sulfuric acid were reacted to form 5-hydroxy-2-(4-chlorophenyl)-1,3-dioxane. The reaction mixture was dissolved in benzene and washed successively with two 50 ml volumes of 5 percent aqueous sodium bicarbonate, two 50 ml volumes aqueous sodium bisulfite and two 100 ml volumes of water. The benzene solution was dried with magnesium sulfate, filtered and evaporated under reduced pressure to form an oil which crystallized, m.p. 95°-100° C (recrystallized from benzene-ligroin).
