Cellulose Sulfuric Acid Catalyzed Esterification of Biodiesel Derived Raw Glycerol to Medium Chain Triglyceride: The Dual Advantage

Abstract

Biodiesel derived raw glycerol represent a copious and inexpensive source which can be used as raw material for a variety of value added products such as 1,3-propanediol, poly hydroxyalkanoate, hydrogen, epichlorohydrin and also lactic acid. So, this work was investigated to study chemical conversion of biodiesel derived raw glycerol and lauric acid to triglycerides of lauric acid via esterification reaction over cellulose sulfuric acid as an efficient, biodegradable and recyclable solid acid catalyst. Synthesized catalyst was characterized by fourier transform infra-red spectroscopy (FT-IR) as well as BET surface area analysis. While, synthesized triglyceride of lauric acid was fittingly characterized by FT-IR as well as 1H and 13C Nuclear magnetic resonance spectroscopic techniques.
