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

Özet

Bu çalışmada reaksiyon girdisi olarak biyodizel yan ürünü gliserinin dimetil karbonat (DMC) ile transesterleşme reaksiyonu sonunda gliserin karbonata dönüşümü araştırıldı. %35 KOH içeren alümina destekli katı bazik katalizör emdirme yöntemi kullanılarak sentezlendi. Reaksiyonda DMC/gliserin oranı ve sıcaklığın (55-85°C) gliserin karbonat verimine etkileri çalışıldı. DMC/gliserin oranının 2/1, sıcaklığın 85°C olduğu, %3 katalizör miktarı ve 3 saat sonunda %92 gliserin karbonat verimi elde edildi. Elde edilen gliserin karbonatın saflığı ve kimyasal yapısı 1H-NMR spektrometresi ile doğrulandı.
