Material Design for Biodiesel by-product Glycerine Evaluation
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2015, Vol 3, Issue 2
Abstract
In this study, transesterification of glycerol which is the byproduct of biodiesel with dimethyl carbonate (DMC) to glycerol carbonate was investigated. Solid basic catalyst which is 35% KOH loaded to alumina was synthesized using the impregnation method. The effects of DMC/glycerol ratio and temperature (55-85°C) on glycerol carbonate yield were studied. The highest yield of glycerol carbonate of 92% was obtained by 3 h of reaction time at 85°C with a DMC/glycerol molar ratio of 2, and using 3 wt.% catalyst. Purity and chemical structure of obtained glycerol carbonate was confirmed by using 1H-NMR spectrometry.
