Cr-substituted mesoporous aluminophosphate molecular sieve:Synthesis,characterization,crystallization kinetics and catalytic activity

摘要：

　　Cr-substituted mesoporous aluminophosphate molecular sieve (Cr-MAP) was synthesized and characterized.Crystallization kinetics curves measured as an index to the relative degree of crystallinity, according to the Arrhenius equation to calculate the apparent nucleation activation energy and crystal growth activation energy of Cr-MAP, which was 63.7 and 14.7 kJ· mol-1, respectively.Cr-MAP had highly catalytic activity for fabricating acetophenone by selectively oxizing ethylbenzene.Using tert-butylhydroperoxide as oxidant and chlorobenzene as solvent at l00 ℃ for 8 h, acetophenone selectivity, acetophenone yield and ethylbenzene conversion reaches 85.4, 62.2 and 72.8 %, respectively.
