実験手順: A mixture of 3.8 g (0.025 g mole) of methyl phenyl carbonate, 3.83 g (0.025 g mole) of trimethylbromosilane, and 0.09 g of tetra-n-butyl phosphonium bromide in 15 ml of sulfolane was heated at 120° C. in a reaction flask equipped with a reflux condenser. After 16 hours of heating, the reflux condenser was replaced by a distillation head and 2.7 g (65 percent yield) of phenoxytrimethylsilane was distilled at reduced pressure from the reaction mixture at a head temperature of 71° C.-72° C./18 mm Hg. equipped with a reflux condenser After 16 hours of heating

実験手順: An apparatus comprising two continuous multi-stage distillation columns as shown in FIG. 3 was employed. Reaction was performed by continuously feeding in a liquid form a mixture of dimethyl carbonate, phenol and Catalyst A to first continuous multi-stage distillation column 1' at a position 1 m below top 17 thereof, which column was comprised of a packed column of 4 m in height and 3 inches in diameter and packed with stainless steel-made Dixon packing (diameter: about 6 mm), from material feeding pipe 2 through conduit 4, preheater 5 and conduit 6, thereby allowing the mixture to flow down the inside of the first continuous multi-stage distillation column. The thermal energy necessary for reaction and distillation was supplied by circulating the column bottom liquid through conduits 8 and 9, reboiler 10 where heating was effected and conduit 11. The gas continuously distilled from column top 17 was led through conduit 12 to condenser 13 where the gas was condensed. A portion of the resultant condensate was recycled to first continuous multi-stage distillation column 1, through conduits 14 and 15 and the rest of the condensate was continuously withdrawn through conduit 16. From the withdrawn condensate, a low boiling point component containing methanol which was a low boiling point reaction product was obtained. A high boiling point component containing the catalyst component and methyl phenyl carbonate was continuously withdrawn from column bottom 18 through conduits 8 and 19. two continuous multi-stage distillation columns Reaction to first continuous multi-stage distillation column 1' at a position 1 m below top 17 to flow down the inside of the first continuous multi-stage distillation column The thermal energy necessary for reaction and distillation heating The gas continuously distilled from column top 17 was led through conduit 12 to condenser condensed A portion of the resultant condensate was recycled to first continuous multi-stage distillation column 1, through conduits 14 and 15 the rest of the condensate was continuously withdrawn through conduit 16 From the withdrawn condensate, a low boiling point component containing methanol which a low boiling point reaction product was obtained was continuously withdrawn from column bottom 18 through conduits 8 and 19

実験手順: A mixture of 3.8 g of methyl phenyl carbonate, 5.64 g of 4-chloro-3-nitrobenzotrifluoride, and 0.17 g of TBPB was heated at 150° C. for 1 hour. All of the carbonate was converted with a 99 percent yield of 2-nitro-4-trifluoromethylphenyl phenyl ether. Distillation of the product yielded 6.65 g (94 percent) of the ether, b.p. 148°-9° C./2 mm.

実験手順: In Example 20, the same procedures as in Example 20 were used, except that the reaction temperature was 180° C., and the contents were reacted for three hours. As a result, the yield of methyl phenyl carbonate was 18%, and the yield of diphenyl carbonate was 21%. Furthermore, methyl benzoate was produced as a by-product with a yield of 39% (the yield is given in terms of phenyl benzoate). was 180° C. the contents were reacted for three hours
