environmentally friendly esterification of various carboxylic acids, phosphonic acids, and phosphinic acids with triethyl orthoacetate or trimethyl orthoacetate under neutral conditions in a typical room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, was successfully carried out to provide the corresponding ethyl esters or methyl esters in high yields.
在中性条件下,在典型的室温离子液体,即1-丁基-3-甲基咪唑六氟磷酸盐中,用原乙酸三乙酯或原乙酸三甲酯对各种羧酸,膦酸和次膦酸进行操作简单,廉价,有效和环保的酯化反应成功地进行了生产,以高收率提供了相应的乙酯或甲酯。
