【摘要】 乙氧基次甲基二苯醚是制备新型的高分子增强材料聚二苯醚衍生物的单体。本文用二苯醚、甲醛和乙醇为原料，在硫酸催化下制得乙氧基次甲基二苯醚，结果表明，二苯醚∶甲醛∶乙醇∶硫酸摩尔比为１∶２．２∶２．８∶２．２，８５℃下反应６小时，乙氧基次甲基二苯醚的得率（以原料二苯醚计算）可达１３１％。更多还原

【Abstract】 Ethoxymethylated diphenyl ether is a monomer for preparing polydiphenyl ether derivatives as new types of high-molecular reinforce. This paper reports the systhesis of ethoxymethylated diphenyl ether by the reaction of diphenyl ether,formaldehyde and ethanol in the presence of sulphuric acid as catalyst。Results show that the yield of ethoxymethylated diphenyl ether to diphenyl ether is 131% with ratio of diphenyl ether to formaldehyde, ethanol, sulphuric acid being 1∶2.2∶2.8∶2.2,reaction temperature 85℃ and reaction time 6 hours.更多还原
