Why Do We Need To Replace Glycerol?

PRODUCTION OF BIODIESEL FROM KARANJA OIL
BY TRANSESTERIFICATION

INTRODUCTION
Majority of the worlds energy needs are supplied through petrochemical sources, coal and natural gases, with the exception of hydroelectricity and nuclear energy. All these sources are finite and at current rate of usage these will be consumed shortly. The high energy demand in the industrialized world as well as in the domestic sector and pollution problems caused due to the widespread use of fossil fuels make it increasingly necessary to develop the renewable energy sources of limitless duration and smaller environmental impact than the traditional one. As a result research and development for alternative sources to replace the petroleum-based fuels has started.
It is slightly soluble in ether, ethyl acetate, and dioxane and insoluble in hydrocarbons. Glycerol has useful solvent properties similar to those of water and simple aliphatic alcohol 's because of its three-hydroxyl groups.
Its surface tension is 64.00 mN/m at 20 °C, and it has a temperature coefficient of -0.0598 mN/(m K).
Glycerol is a reactive molecule that undergoes all the usual reactions of alcohols. Under neutral or alkaline conditions, glycerol can be heated to 250ºC without formation of acrolein. Reactions with glycerol are therefore best carried out under alkaline or neutral conditions, alkaline glycerol begins to dehydrate forming ether-linked polyglycerols. At room temperature glycerol rapidly absorbs water. When dilute it is attacked by
