Abstract

Un désémulsifiant comprend le produit de réaction de a) une combinaison d'un monoglycéride et d'un polyéthylène glycol (PEG), b) un acide ayant au moins deux groupes carboxyle, un ester complet ou partiel de celui-ci, un anhydride de celui-ci et des combinaisons de ceux-ci, et c) éventuellement, un acide gras, un alcool gras et des combinaisons de ceux-ci. Un procédé de désémulsification d'une émulsion eau dans huile ou huile dans l'eau comprend l'ajout du désémulsifiant à l'émulsion et la séparation de l'émulsion en une phase huileuse et une phase aqueuse.
