Abstract:
Several commercial grades of glycerine are produced with different specifications
regarding purity and glycerine content. Its chemical properties are
the reason for its wide application in such industries as pharmaceuticals,
cosmetics, and explosive and epoxy resin manufacturing. Natural oils and fats
are important resources from which glycerine is recovered, two main processes
being used: fat-splitting hydrolysis (from which 15-20% crude results) and
saponification (crude recovered from spent lyes at 10-15% glycerine content).
