Reaction Steps

In the same way as in Example 13, 69.1 g (0.5 mole) of p-hydroxybenzoic acid and 216.2 g (2 moles) of benzyl alcohol were reacted at 120° C. for 4 hours in 138 g of toluene in the presence of 1.44 g of p-toluenesulfonic acid as a catalyst. The yield of benzyl p-hydroxybenzoate was 26%. Dimerization and dehydration of benzyl alcohol occurred simultaneously, and dibenzyl ether was formed in a ratio of as high as 45%.
