摘　　要：以锆镍双金属离子低聚物为交联剂合成了交联粘土催化剂（简称Ｚｒ－Ｎｉ－ＣＬＢ），用ＸＲＤ，ＳＥＭ，ＤＴＡ－ＴＧ等表征手段，对其结构、稳定性进行了研究，同时用乙酸与正丁酸的酯化反应证实了该催化剂具有较好的酯化催化活性．A cross linked bentonite catalyst(Zr-Ni-CLB) was prepared by the reaction with a low copolymer of zirconium and nickel. Its structure and thermal stability were investigated by means of XRD,SEM,and DTA TG. The results of activity assays for the esterification of acetic acid with butanol showed that this catalyst had good catalytic performance.
