Abstract

The typical biodiesel production process generates glycerol as a byproduct due to the use of alcohol as an acyl acceptor. The rising necessity for biodiesel production has resulted in an excess of crude glycerol, surpassing market needs and often being treated as waste. For the enhancement of the economic sustainability of the industry, an efficient valorization strategy is required. This study explores the optimization of the process parameters that influence the conversion of crude glycerol into triacetin. The research focuses on optimizing process parameters to maximize triacetin
temperature, and molar ratio. The optimization results showed that the highest triacetin selectivity was achieved under optimal conditions of 60% at M:O molar ratio of glycerol to ethyl acetate 1:2.59, Reaction time of 2.05 h, and reaction temperature of 27°C The developed process offers an efficient and scalable approach to crude glycerol valorization, supporting the economic viability of biodiesel production while reducing waste.
