一、前言硅铝酸盐及杂原子硅铝酸盐分子筛作为一种有效催化剂已有广泛的研究。作者于1984年对于杂原子硅铝酸盐分子筛的研究进展进行过总结。磷酸铝系列(AlPO_4-n)分子筛是1982年由 Wilson,Flanigen 等人为首的美国 UCC 公司 Tarrytown 技术中心开发的一类新型分子筛。在 AlPO_4-n 分子筛骨架中首次不出现硅氧四面体,它的开发为新型分子筛合成开辟了一条新途径。由于等价磷酸铝系列分子筛具 I. INTRODUCTION Aluminosilicate and heteroatom aluminosilicate molecular sieves have been extensively studied as an effective catalyst. In 1984, the author summarized the research progress of heteroatom aluminosilicate molecular sieves. Aluminum phosphate series (AlPO_4-n) molecular sieve is a new type of molecular sieve developed by Tarrytown Technology Center of UCC Corporation in 1982 headed by Wilson, Flanigen and others. For the first time in the AlPO 4-n molecular sieve framework does not appear silicon tetrahedron, its development for the new molecular sieve synthesis has opened up a new way. Due to the equivalent series of aluminum phosphate molecular sieve
