采用水热法合成了AlPO_4-5和CuAPO-5′分子筛。对新合成的样品进行了XRD、IR、DTA和SEM分析,初步确认它们具有分子筛结构。考察了CuAPO-5′和AlPO_4-5负载磷酸铜钙催化剂对乙炔水合等反应的催化活性。实验结果表明,它们具有良好的催化性能,可望有较好的应用价值。
AlPO 4 -5 and CuAPO 5 ’molecular sieves were synthesized by hydrothermal method. The newly synthesized samples were analyzed by XRD, IR, DTA and SEM, and initially confirmed that they have molecular sieve structure. The catalytic activity of CuAPO-5 ’and AlPO 4 -5 supported calcium copper phosphate catalysts for the acetylene hydration reaction was investigated. The experimental results show that they have good catalytic properties and are expected to have good application value.
