Abstract

SE PREPARA POLI-N-BUTENO A PARTIR DE UNA CORRIENTE DE ALIMENTACION DE HIDROCARBURO C4 MIXTA QUE CONTIENE MENOS DE APROXIMADAMENTE 5% EN PESO DE ISOBUTILENO USANDO UN SISTEMA CATALITICO DE CLORURO DE ORGANOALUMINIO-HCL DONDE SE INTRODUCE HCL POR SEPARADO EN LA CORRIENTE DE ALIMENTACION PARA FORMAR ORGANOCLORURO EN LA CORRIENTE DE ALIMENTACION. EL PRODUCTO POLIMERICO QUE TIENE UNA DISTRIBUCION DE PESO MOLECULAR MUY ESTRECHA SE OBTIENE EN UNA GAMA DE MN DE 300 A 900. LOS DETERGENTES DERIVADOS DE ESTE POLI-N-BUTENO EXHIBE UN RENDIMIENTO SUSTANCIALMENTE MEJORADO EN LAS COMPOSICIONESDE ACEITE LUBRICANTE.
