Abstract:
The invention relates to the defoaming of ionic liquids and also to compositions comprising at least one ionic liquid and at least one antifoam and, if appropriate, a solvent and/or further auxiliaries or additives.
Abstract:
A method of defoaming diesel fuel by adding an organofunctionally modified polysiloxane of the general Formula I ##STR1## wherein R.sup.1 are alkyl groups with 1 to 4 carbon atoms or aryl groups with the proviso that at least 80% of the R.sup.1 groups are methyl groups,R.sup.2 are the same or different in the molecule30 to 90% of R.sup.2 having the same meaning as R.sup.1, and70 to 10% of R.sup.2 consisting of a mixture of R.sup.2A and R.sup.2B groups which differ in polarity,is described. The inventive polysiloxane is added in an amount of 0.5 to 50 ppm, based on the diesel fuel.
