对二甲氨基苯甲酸异辛酯(EHA)的合成方法
摘要：
本发明涉及对二甲氨基苯甲酸异辛酯(EHA)的合成方法和生产工艺研究，本发明的方法是以对卤代苯甲酸为原料，经过与二甲胺反应，再与异辛醇反应，然后经减压蒸馏除去溶剂及异辛醇，得到对二甲氨基苯甲酸异辛酯(EHA)，产品纯度大于98％，总收率85％以上。本发明工艺具有反应条件温和，操作简单，对环境友好，溶剂易回收套用的特点，适合应用于工业生产。
摘要（英）：

The invention relates to a method for synthesizing 2-Ethylhexyl p-dimethylaminobenzoate (EHA) and production technology research thereof. The method comprises the steps of: reacting halogeno benzene benzoic acid as raw materials with dimethylamine and isooctanol, removing a solvent and isooctanol via reduced pressure distillation to obtain the 2-Ethylhexyl p-dimethylaminobenzoate (EHA), wherein the product has the purity being greater than 98% and the overall yield being 85%. The process has the characteristics of mild reaction condition, simple operation, environmental protection and easy recycling of the solvent, and is suitable for industrial production.
