Abstract
In this work, six ionic surface-active alkyl ammonium halides were synthesized and evaluated as demulsifiers of W/O emulsions obtained from a Mexican heavy crude oil. A centrifugation test was employed as a fast method for following the kinetics of the demulsification process with the synthesized demulsifiers. Trioctylmethylammonium bromide showed the best performance as demulsifier.Keywords
