摘要
用无机方法合成了钛硅分子筛催化剂TS-1,并优化了TS-1催化环己酮氨氧化反应的条件。结果表明,无机催化剂可以取代有机催化剂。同时,物料比、溶剂以及温度都对氨氧化反应有很大影响。适当调整反应条件,可得到较好的结果。其最优的反应条件为:n(氨)∶n(酮)=2,n(H2O2)∶n(酮)=1.5,溶剂用蒸馏水,n(水)∶n(酮)=7.5,反应温度为74℃。
TS-1 zeolite was synthesized from inorganic materials. Ammoximation of cyclohexanone in the presence of titanium-silicalite-l(TS-1) catalyst was studied. The results showed that TS-1 zeolite synthesized from inorganic material could substitute those synthesized from organic material; ratio of reactants, sort of solvent and temperature had remarkable influence on the reaction. The optimum reaction condition is as follows: n (NH3) : n (cyclohexanone) = 2, n (H2O2) : n (cyclohexanone) = 1.5, H2O as the solvent, n (H2O) : n (cyclohexanone) = 7.5, reaction temperature 74℃.
