Preparation and Characterization of Soap Nut Biodiesel

Biodiesel is an alternative fuel sources which is used in engine. Biodiesel produced from animal fat, waste cooking oil, and soap-nut oil (sapindus mukorossi), soybean, jetropha oil etc. Biodiesel is very useful for developing India because Biodiesel is useful for environment. we know the diesel, and petrol are fossil fuels they will exhaust in future that’s why we need to focus on Biodiesel which is renewable energy sources the method to make biodiesel is first Esterification of soap-nut oil, methanol and H2SO4 added with soap-nut oil at 60 °C reaction time for 1h. The base catalyst KOH was used in transesterification to convert the soap-nut oil into biodiesel. In this research paper testing the viscosity before the transesterification and after the transesterification.
