【摘要】 探讨了苯氧基乙酸烯丙酯工业生产的条件。对苯氧基乙酸合成的最佳摩尔比、反应温度及后处理作了系统的试验。在后一部酯化反应中就不同催化剂如浓硫酸、磷酸和阳离子交换树脂对产率的影响以及一系列酯化条件进行了对比试验,从而提出了苯氧基乙酸烯丙酯工业生产较合理的工艺路线。更多还原

【Abstract】 The conditions for industrial production of allyl phenoxyacetatc arc studied. The systematic experiments have been done on the optimum molar ratio, reaction temperature and aftertreatment of the synthesis of phenoxyacetic acid. It is found that the yield can be influenced by various catalysts, e. g., cone. sulfuric acid, phosphoric acid and ion exchange resin and various reaction conditions in csterification. Therefore, a reasonable procedure in commercial production of allyl phenoxyacctate is proposed.更多还原
