采用水热法合成了 ZAPO-5′。对新合成的样品进行了XRD、IR、DTA、TG分析,初步确认其为分子筛型催化剂。考察了ZAPO-5′对乙炔水合反应的催化活性,实验发现它可使乙炔水合反应的转化率达到近90％。研究结果表明,ZAPO-5′在催化领域里具有潜在的应用价值。 ZAPO-5 ’was synthesized by hydrothermal method. The newly synthesized samples were analyzed by XRD, IR, DTA and TG, and initially confirmed as molecular sieve catalyst. The catalytic activity of ZAPO-5 ’on acetylene hydration was investigated. It was found that the conversion rate of acetylene hydration reached nearly 90%. The results show that ZAPO-5 ’has potential application in catalytic field.
