NEW SYNTHESIS ROUTE FOR GLYCOLS FROM UNSATURATED VEGETABLE OILS USING HETEROGENEOUS ACIDIC CATALYSTS

Unique structures of fats and oils, together with their physical characteristics provide them a large range of applications; the reactive unsaturated fatty acids are commonly used to generate compounds with greater diversity of application (pharmaceutical, cosmetics and food industries). Results obt...
