For total utilization of waste edible oil, the reaction optimization of biodiesel fuel (BDF) production and the polymerization of by-product glycerin were investigated. BDF was prepared by alkali-catalyzed transesterification with methanol. To optimize the reaction condition, the neural network (NN) analysis was adopted. NN model was built with the relationship among the several reaction conditions and the chemical properties of BDF. The NN model suggested good prediction to the properties in unknown conditions. The exhaust fumes of BDF prepared from virgin and waste oils were similar. The glycerin was polymerized with succinic acid by non-catalyzed dehydration. The increase of the viscosity with the weight loss after reaction was observed, and it suggested the progress of the polymerization. As the model reaction of by-product glycerin during BDF production, the polymerization of glycerin, succinic acid and sodium oleic acid was investigated. In the system with sodium oleic acid, more viscous product was obtained comparing with the glycerin-succinic acid system.
