Abstract

Un metodo para reducir la acumulacion y deposicion de asfalteno a partir de un fluido que contiene asfalteno, tal como crudo, cuyo metodo comprende la adicion al fluido de un compuesto de la formula (I): (ver formula) en la cual A es un sistema de anillo opcionalmente sustituido que contiene de 6 a 14 atomos de carbono; n es al menos 1 y puede ser igual al numero de posiciones disponibles para sustitucion en A; cada X es independientemente un grupo de enlace; y cada R es independientemente un grupo hidrocarbilo que contiene 10 a 25 atomos de carbono.
