Abstract

Procédé pour le controle de la formation de mousse des combustibles hydrocarbures liquides, caractérisé en ce qu'on leur ajoute certains copolymères de siloxane polyoxyalkylène comme agents anti-mousse. Les copolymères préférés répondent à la formule générale Me3SiO(Me2SiO) x (MeR'SiO)ySiMe3 dans laquelle Me est méthyle,R' représente Q(OA)nOZ où Q est un groupe divalent attaché au Si, A est éthylène, n vaut de 10 à 15,Z est hydrogène ou OCR'', R'' étant un groupe monovalent, le rapport x:y étant de préférence compris entre 3:1 et 7:1.
