碱相转移催化脱水法合成柠檬腈的研究
Research on the Synthesis of Lemonile by Dehydration through Phase Transfer Base Catalysis
【摘要】 研究了不同碱对柠檬肟的催化脱水效果及不同 PTC的催化作用效果 ,并用正交实验设计法确定了使用 KOH- TBAB催化脱水法合成柠檬腈的最佳反应条件。在此条件下 ,柠檬肟到柠檬腈产率达 91 .0 %。
【Abstract】 The catalytic dehydration of lemonile with various alkalis and PTC was studied. The optimal conditions dehydration to lemonile for KOH TBAB catalytic by orthogonal design were determined. Under these conditions, the yield of lemonile from citraloxime was up to 91.0%.
