Versuchsvorschrift

The reaction mixture was cooled to 50° C. and the residual pressure was released, and 100 ml of benzene was added into the autoclave to dissolve the oil layer. Then, the catalyst was removed by filtration, and the filtrate was allowed to stand still to cause phase separation, and the benzene layer was recovered and washed with 120 ml of water three times, and benzene was removed by distillation under reduced pressure to give an oily product. From the results of the analysis of the oily product by gas chromatography according to the internal standard method, it was found that the oily product comprised 98.8% of 3-phenoxybenzyl 2-(4-ethoxyphenyl)-2-methylpropyl ether and 0.3% of unreacted starting 3-phenoxybenzyl 2-(3-chloro-4-ethoxyphenyl)-2-methylpropyl ether, and that the content of each of 3-phenoxytoluene and 4-ethoxyneophyl alcohol formed by cleaving of the ether linkage was lower than 0.3%. The amount of the obtained oily product was 53.8 g, and the yield was 96.7%.
