Prins缩合反应合成4-丁基-1,3-二氧六环的研究

Synthesis of 4-butyl-1,3-dioxane by Prins condensation

以1-己烯和多聚甲醛为原料,使用离子交换树脂作为催化剂,利用Prins反应催化合成新型含氧燃料4-丁基-1,3-二氧六环。采用GC-MS和H-NMR手段对合成产物进行分析表征,并以柱层析分离将4-丁基-1,3-二氧六环分离出来,并优化了合成4-丁基-1,3-二氧六环的条件。

A novel oxygen-containing fuel of 4-butyl-l ,3-dioxane was synthesized from 1-hexene and paraformaldehyde via Prins re-action. A homemade acid catalyst ion-exchange resin was adopted for the reaction. The main products were characterized by the GC- MS and H-NMR. The product 4-butyl-l ,3-dioxane was separated through column chromatography method. And the condition for the synthesis of 4-butyl-l ,3-dioxane were optimized.
