Abstract

Results of crystallization of two 1.0Al₂O₃ ⋅ 1.0P₂O₅ ⋅ 0.4SiO₂ ⋅ 1.0DPA ⋅ 50H₂O silicoaluminophosphate gels are compared; the gels are synthesized using pseudoboehmite in one case and aluminum isopropoxide in the other. It is shown that the choice of aluminum source significantly affects the phase composition of the resulting silicoaluminophosphate gels and the physicochemical properties of SAPO-11 samples crystallized from the gels and their catalytic properties in the vapor-phase isomerization of cyclohexanone oxime to caprolactam.

细晶SAPO-11分子筛的合成及其理化和催化性能分析

摘要

2个1.0Al的结晶的结果₂ ö ₃ ⋅1.0P ₂ ö ₅ ⋅0.4SiO ₂ ⋅1.0DPA⋅50H ₂ ö硅铝凝胶进行比较; 在一种情况下，使用假勃姆石，另一种情况下使用异丙醇铝来合成凝胶。结果表明，铝源的选择会显着影响所得硅铝磷酸盐凝胶的相组成以及从凝胶中结晶出的SAPO-11样品的理化性质及其在环己酮肟气相异构化为己内酰胺中的催化性能。
