Over the last few years, the use of Glycerin has increased manifold times. Glycerin has many extensive uses, in different industries, starting from food and pharmaceuticals to rocket engineering. Very little academic literature exists on how to treat and recover Glycerin, produced as Glycerol in saponification reactions. Further there is almost no literature available for the recovery of Glycerin produced from the saponification of oils. This book focuses on the experiments and results for the production of soap from oils, estimation of glycerol, recovery of glycerin from a synthetic glycerol and water solution and study of its behavior. It also covers in detail the study of the behavior of glycerol with time at a temperature of 90 0C – 100 0C. The study is done using edible oil (karanja oil) and a non-edible oil (rice-bran oil). The process of recovery f glycerol is standardized. This work is aimed for utilization by researchers, industrialists’ and traditional business’. Apart from this it will be especially relevant and usable by the students of Food sciences, Bio sciences, Pharmacy, Chemistry and Chemical engineering for carrying out research in the recovery of Glycerol.
