In this work, it was described the preparation and characterization of a solid acid catalyst obtained by mixture Cr/Al oxides (CRAL).The tested in transesterification reaction babassu oil with 5% free fatty (FFA).The results textural acidity characteristics CRAL were: area (56 m 2 g -1 ), pore size (7.0 µm), total (182.28 µmol wherein Brönsted sites are most active.Powder X-ray diffractometry (XRD), scanning electron microscopy (SEM) energy-dispersive spectroscopy (EDX) show three phases (Cr...
Glycerol, a by-product from biodiesel production can react with di-carboxylic organic acids, resulting in polyesters, and be used the composition of urea/formaldehyde or phenol/formaldehyde resins to improve qualities adhesion moisture resistance them. In this work, six kinds derived glycerol, named as GAA (glycerol/adipic acid), GAAU acid/urea), GAF (glycerol/phtalic GU (glycerol/urea), GUF (glycerol/urea/formaldehyde) GF (glycerol/formaldehyde), were synthesized. The carboxylic acids had...
