摘要: Cellulose is a natural substance, macromolecular, non-toxic, renewable and biodegradable origin, whose chemical structure can be modified by replacing the hydroxyls present on macromolecule thus obtain products with varying properties of use. With increasing worldwide attention to environmental pollution, obtaining new from cellulose modification has been carried out applicability in various industries among them extraction production oil industry. This study shows action surfactant substance obtained sisal xanthates ( Agave sisalana ) lauric alcohol, laboratory bench, heavy waxing phenomenon through appearance initiation temperature measurement paraffin crystals (TIAC) flow activation energy. The results these experiments showed that this did not reduce TIAC values sample question but promoted reduction up 8 kJ /mol energy for additivated presence brine 1000ppm.
