植物生长调节剂2-(2,4-二氯苯氧基)三乙胺的合成新方法

A Novel Synthesis of 2-(2,4-Dichlorophenoxy) Triethylamine.

以2,4 二氯苯酚为原料,采用相转移催化剂,经过醚化、胺化反应合成了2 (2,4 二氯苯氧基)三乙胺,总收率大于80%。研究了反应物的摩尔配比、反应时间及反应温度对2,4 二氯苯酚和二溴乙烷的醚化反应的影响,优惠工艺条件为:2,4 二氯苯酚与1,2 二溴乙烷配比为1∶30(mol/mol),反应温度80℃、反应时间10h。通过红外光谱、核磁共振氢谱和元素分析确定了目标化合物的结构。

A novel synthesis of 2 (2,4 dichlorophenoxy) triethylamine was investigated. 2 (2,4 dichlorophenoxy) triethylamine was prepared by phase transfer catalyst from 2,4 dichlorophenol. The yield of reaction was above 80%. The effects of some factors such as reactants ratio, catalysts, reacting time and temperature etc, were discussed. The structure of product was confirmed by elemental analysis, IR and 1 HNMR.
