| titleOfInvention | Anti-foam agent, especially for aqueous systems |
| abstract | R 1 = z-wertiger Kohlenwasserstoffrest oder, falls z = 1 ist, ein Wasserstoffrest, R 2 = Wasserstoff-, Alkyl-, Aryl-, -CONHR 3 -,n oder -Rest, wobei höchstens % aller Reste R 2 Wasserstoffreste sein dürfen, R 3 = einwertiger Kohlenwasserstoffrest, R 4 = geradkettiger Alkylrest mit im Mittel 4 bis 16 Kohlenstoffatomen oder Methyl- oder Wasserstoffrest, wobei aber höchstens 90 Mol-% der Reste R 4 Methyl- oder Wasserstoffrest sein dürfen, n = ganze Zahl ≧ 2, z = ganze Zahl von 1 bis 3. The invention relates to an agent for preventing or eliminating foam, especially in aqueous solutions. The active substances are polyoxyalkylene compounds which contain oxyalkylene groups with 4 to 16 carbon atoms and of the formula correspond, where the substituents and indices have the following meaning: R 1 = z-valued hydrocarbon residue or, if z = 1, a hydrogen residue, R 2 = hydrogen, alkyl, aryl, -CONHR 3 -, or -Rest, at most % of all residues R 2 may be hydrogen residues, R 3 = monovalent hydrocarbon radical, R 4 = straight-chain alkyl radical with an average of 4 to 16 carbon atoms or methyl or hydrogen radical, but at most 90 mol% of the radicals R 4 may be methyl or hydrogen radical, n = integer ≧ 2, z = integer from 1 to 3. |
