| contents | Evaluation of the catalytic activity of lipases immobilized on chrysotile for esterification Jane E. S. Silva Paulo C. Jesus Multidisciplinaria (Ciencias Naturales y Exactas) esters lipases chrysotile In the present work, the ester synthesis in organic media catalyzed by lipases immobilized on chrysotile was studied. Lipases of different sources (Mucor javanicus, Pseudomonas cepacia, Rhizopus oryzae, Aspergillus niger and Candida rugosa) were immobilized on chrysotile, an inexpensive magnesium silicate, and used for esterification of hexanoic, octanoic and lauric acid with methanol, ethanol, 1-butanol and 1-octanol at 25oC in hexane as solvent. The best results were obtained with Mucor javanicus lipase and lauric acid giving yields of 62-97% of ester. 2003 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32775203 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.75 |
