Experimental and Calculation Investigation of the Efficiency of Nonanalytic Biodiesel Synthesis in Subcritical Methanol

Experimental and Calculation Investigation of the Efficiency of Nonanalytic Biodiesel Synthesis... It was experimentally determined for the first time that, for noncatalytic biodiesel synthesis, the dependence of the partial pressure of methanol on the mole fraction of methanol in rapeseed oil shows a pronounced negative deviation from Raoult’s law. Investigation of the change in the partial pressure of methanol in the noncatalytic reaction of the transesterification of rapeseed oil in 8 h of the reaction at 220°C demonstrated that the efficiency of the increase in the molar excess of methanol decreases, and, at a more than 10-fold molar excess, the amount of the reacted methanol remains unchanged. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Doklady Chemistry Springer Journals

Abstract

It was experimentally determined for the first time that, for noncatalytic biodiesel synthesis, the dependence of the partial pressure of methanol on the mole fraction of methanol in rapeseed oil shows a pronounced negative deviation from Raoult’s law. Investigation of the change in the partial pressure of methanol in the noncatalytic reaction of the transesterification of rapeseed oil in 8 h of the reaction at 220°C demonstrated that the efficiency of the increase in the molar excess of methanol decreases, and, at a more than 10-fold molar excess, the amount of the reacted methanol remains unchanged.
