How to produce biodiesel from vegetable oil. Transesterification is the most common method used to reduce viscosity of vegetable oils and produce biodiesel. In addition to transesterification of TAG biodiesel FAAE can be produced from free fatty acid FFA through esterification. An ideal transesterification reaction differs on the basis of variables such as fatty acid composition and the free fatty acid content of the oil.

The main reaction takes place with methanol which is a type of alcohol in the presence of a strong hydroxide catalyst such as sodium hydroxide. In this lab we will be starting with 200 mL of vegetable oil. The recipe for making biodiesel from virgin vegetable oil using base as a catalyst is simple.

Biodiesel or fatty acid methyl ester is a clean burning alternative fuel. The synthesis of biodiesel by transesterification of vegetable oils was carried out in this study. Biodiesel can be made from any vegetable oil including oils pressed straight from the seed such as soybeans sunflower canola olive oil and coconut.

Into biodiesel with the dried remainder further reprocessed to create ethanol. Almost all biodiesel is produced from virgin vegetable oils using the base-catalyzed technique as it is the most economical process for treating virgin vegetable oils requiring only low temperatures and pressures and producing over 98 conversion yield provided the starting oil is low in moisture and free fatty acids. In contrast FFA is not an ester.

Although the reaction itself is fairly simple there. Transesterification reaction is quite sensitive to various parameters. This biodiesel also can be made from waste.

In experiments with methanol using the lowest tested amount catalyst 085 g KOH and 023 g NaOH a good yield of biodiesel is obtained. General way to produce biodiesel fuel is by transesterification of vegetable oil with methanol in the presence of either alkaline or strong acid catalysts. For every 1L of vegetable oil add 02 L of methanol and 85 g of KOH.
