1,2 – cikloheksāndiola un cikloheksanola dehidratācija jonu šķidrumos

Abstract

Darbā ir pētīta trans-1,2-cikloheksāndiola un cikloheksanola dehidratācija skābos jonu šķidrumos. Mainot reakcijas laiku, temperatūru, izejvielas un katalizatora attiecības, tika atrasti apstākļi, kuros abas izejvielas, izreaģē pilnīgi, veidojot dažādus dehidratācijas produktus. Sintezētie jonu šķidrumi ir kvantitatīvi raksturoti ar AEŠH/MS, bet kvalitatīvi ar 1H KMR. Dehidratācijas reakcijās iegūto produktu kvalitāte noteikta ar GH/MS metodi.

The work describes dehydration reaction of trans-cyclohexane-1,2-diol and cyclohexanol in acidic ionic liquids. By changing the reaction time, temperature, the ratio of initial substance and catalyst, there have been found the conditions in which trans-cyclohexane-1,2-diol as well as cyclohexanol reacted completely and formed various dehydration products. The quality of synthesized ionic liquids has been characterized by HPLC/MS and the quantity has been identified by PMR. The content of obtained products has been determined by GC/MS method.
