A new catalyst mixture, namely trifluoromethanesulfonic acid + N-methylimidazolium trifluoromethanesulfonate (CF₃SO₃H + [mim][CF₃SO₃]), is developed to overcome long-standing problems of commercial catalysts and catalytic distillation for 1,3,5-trioxane synthesis. CF₃SO₃H serves as a catalyst to accelerate the main reaction and [mim][CF₃SO₃] serves as an extractive distillation agent to promote phase separation. Unlike the conventional design methods whose purpose is to increase catalytic activity and selectivity, this catalyst mixture is designed to significantly enhance phase separation.

一种合成1,3,5-三恶烷的新型催化剂混合物

开发了一种新的催化剂混合物，即三氟甲磺酸 + N-甲基咪唑鎓三氟甲磺酸盐 (CF ₃ SO ₃ H + [mim][CF ₃ SO ₃ ])，以克服长期存在的商业催化剂和催化蒸馏 1,3 的问题， 5-三恶烷合成。CF ₃ SO ₃ H用作催化剂以加速主反应，[mim][CF ₃ SO ₃ ]用作萃取蒸馏剂以促进相分离。与旨在提高催化活性和选择性的传统设计方法不同，这种催化剂混合物旨在显着增强相分离。
