Kinetics and isotope effect of brown coal liquefaction in ethanol

Reaction Kinetics and Catalysis Letters Aims and scope Submit manuscript

Abstract

Liquefaction kinetics are described by a first-order equation. Deuterium introduction into the α-position of ethyl alcohol produces a considerable kinetic isotope effect. This effect is suggested to be due to the hydrogen donor capacity of the initial ethyl alcohol α-CH2-groups or of ethyl substituents inserted into the aromatic fragments of coal after alkylation.

Abstract

Кинетика ожижения описана уравнением первого порядка. Введение дейтерия в α-положение, в спирте сопровождается значительным изотопным эффектом, который может быть связан с водородно-донорной способностью α-CH2-групп спирта или его этильных радикалов, внедрившихся в ароматические фрагменты угля в результате реакции алкилирования.
