| 摘 要： | 研究了使用盐、聚乙二醇时为相转移催化剂、丙二酸二乙酯与烷基化试剂在碳酸钾存在下的固—液相转移烷基化反应。研究表明,在一定反应时间内对于盐催化剂加入量超一定量后,产物收率不再提高;若在此界量后,协同使用盐与聚乙二醇,则产率仍可提高,从而表现出协同作用。

| Abstract: | The phase -transfer catalyzed alkylation reaction of diethyl malonate by using solid potassium carbonate as base could not be accelerated above a limiting reaction rate by increasing the concentration of the onium salt catalyst. The rate limit could be exceeded by using polyethylene glycols in addition to an onium salt. |
