摘要
用氧化物对ＮａＺＳＭ－５分子筛进行改性来调节其表面酸碱性，已越来越受到人们重视，本文报道用Ｌｉ２Ｏ、Ｌａ２Ｏ３双组份对ＮａＺＳＭ－５进行改性，并将改性分子筛用作甲醇和碳酸乙烯酯（简称ＢＣ）反应制碳酸二甲酯（简称ＤＭＣ）体系的催化剂。文献报道用作此反应...
Modification of NaZSM 5 by Li 2O and La 2O 3 was made.Characterication of modified NaZSM 5 by XRD and IR showed that addition of Li 2O cause the change of structure of ZSM 5 zeolite.The activity experiments results indicated that Li La/NaZSM 5 catalyst showed much better transeterification activities than NaZSM 5.
