研究了一种快速简便合成苯氧乙酸酯的方法.在微波促进下,以硅胶吸附的硫酸(SiO2-H2SO4)为催化剂,各种苯氧乙酸与醇类快速发生酯化反应生成相应的苯氧乙酸酯,该方法具有反应时间短(仅需3~5min)、产率较高及催化剂可循环利用等优点.
A rapid and facile method for the synthesis of phenoxyacetate was developed.After the microwave promoted the esterification of various phenoxyacetic acids and alcohols with silica-adsorbed sulfuric acid (SiO2-H2SO4) as catalyst, the corresponding benzene The method has the advantages of short reaction time (only 3 to 5 minutes), high yield and recyclable catalyst.
