Obtención de un tensoactivo a partir del proceso de recuperación de sebo de las industrias de curtiembre.

Abstract

In order to develop new processes that seek to take advantage of the solid waste generated by the tannery industries, the possibility of recovering the fats generated in the skinning stage is opened, since animal fat contains mainly fatty acids (linoleic, myristic , stearic, palmitic and oleic) of a commercial value that can be extracted and transformed into by-products for industrial use, in addition to increasing the profitability of this type of companies and reducing their environmental impact. The pieces of skin with fat attached to them are separated and three residues are obtained: fat, liquid and sludges, being the object of study the fat without considering the rest of residues. With the fat recovered, physical-chemical analyzes were carried out (index of saponification, iodine, acidity and peroxide) and subsequently laboratory tests that began with the transformation of fat into an alcohol, followed by sulfonation and finally neutralization, tests that result in the formation of a surfactant from this type of fats.
