【摘要】 以三羟甲基丙烷、固体氢氧化钠和氯丙烯为原料,丁醚为反应介质和共沸脱水剂,通过对影响产品收率和产品质量关键因素进行控制,确定了最佳的工艺条件。实验结果表明,所得产品收率高,单醚质量分数小于8%,二醚质量分数大于90%,三醚的质量分数小于1%,总醚质量分数大于99%。产品质量稳定可靠,各项指标均优于国内外同类产品。更多还原

【Abstract】 The new process for preparation of trimethylolpropane diallyl ether is developed using solid sodium hydroxide,trihydroxy methyl propane and allyl chloride as raw materials,and butyl ether as reaction medium and azeotropic dehydrating agent.The key factors affecting the product yield and product quality are controlled and the optimum process conditions are determined.The results show that the high yield of trimethylolpropane diallyl ether can be achieved with less than 8% of ME,more than 90% of DE and less than 1% of TE.The total ether content is greater than 99%.The target product with stable and reliable product quality is obtained with all the indicators better than similar products at home and abroad.更多还原
