【摘要】 研究了氯化稀土对柠檬酸与正丁醇酯化反应的催化性能。结果表明，单一氯化稀土和混合氯化稀土均具有很好的催化活性。为此，系统地研究了混合氯化稀土催化合成柠檬酸三丁酯的工艺条件，确定了合适的工艺流程更多还原

【Abstract】 The catalytic activity of rare earth chlorides for esterification reaction between citric acid and n butyl alcohol was investigated.It was found that single or mixed rare earth chlorides are all good catalysts for the synthesis of tributyl citrate.And then,more detail synthesis conditions of tributyl citrate were examined with mixed rare earth chlorides as catalyst,hence a suitable technology was proposed.更多还原
