以己二酸、N,N-二乙氨基乙醇和柠檬酸为主要原料,合成了一种具有双活性基的高效植物生长调节剂己二酸双二乙胺基乙醇酯柠檬酸盐。探讨了反应温度、时间及物质的量比等对产率的影响,最适宜的工艺条件:己二酸与N,N-二乙氨基乙醇的物质的量比为1∶2.5,以二甲苯为溶剂,硫酸氧钛为催化剂,在145℃反应8h,产率为90.5%。采用FT IR,1 H NMR表征产物的分子结构,室内种子萌发实验表明其具有较好的生物活性。 An adipic acid bisdiethylaminoethanol ester citrate with double active groups was synthesized with adipic acid, N, N-diethylaminoethanol and citric acid as the main raw materials. The effects of reaction temperature, time and mass ratio on the yield were discussed. The most suitable conditions were as follows: the molar ratio of adipic acid to N, N - diethylaminoethanol was 1: 2.5, Solvent and titanyl sulfate as catalyst, the reaction was carried out at 145 ° C for 8h, and the yield was 90.5%. The molecular structure of the product was characterized by FT IR and 1 H NMR. The indoor seed germination experiment showed that it had good biological activity.
