Physico-Chemical Analysis of Biodiesel Derived Glycerin and Saponification of Crude Glycerin with Different Concentrations of Sodium Hydroxide Lye
Doddabasawa [2] | Ravikumar Patil [2]
Abstract: Crude glycerin which was obtained during the production of biodiesel with 50 LBP production unit from pongamia seeds was analysed for the free fatty acid; viscosity; pH; color; odour and density and were found that 1.82 %; 118 csts; 8.0; dark brown; unpleasant and 1.5g/cm3 respectively. The crude glycerin was treated with lye for the preparation of soap with different concentrations. The combination of glycerin (1000ml) ; water (100ml) ; sodium hydroxide lye (50g) and raw caustic soda (10g) and lemon juice (50ml) was shown better result with respect to removing of stains; household utensils and oil equipments and pH was in the usability range of 8.0
Keywords: Crude glycerin, sodium hydroxide lye, biodiesel, transesterification, lemon juice, caustic soda, edible and non-edible seeds
