| abstract | Ethylene oxide condensates of general formula Rz(Cu2Cu2O)xR1, where R is an alky radical, saturated or unsaturated, containing not less than 10 carbon atoms, or a cycloalkyl, aralkyl or an aryl radical, Z is -O-, -COO-, -NR11- or -CONR11-, wherein R11 is hydrogen or an alkyl radical, saturated or unsaturated, or a cycloalkyl or an aralkyl or an aryl radical or group (Cu2Cu2O)yR111, wherein R1 and R111 are hydrogen or an alkyl radical, the same or different, and wherein x and y are integers, the same or different, said condensates being such that x+y or x (if y is absent) has a value of 1 to 20 are obtained according to conventional methods. Thus appropriate proportions of ethylene oxide are reacted with an aliphatic alcohol containing not less than 10 carbon atoms, e.g. dodecyl alcohol, octadecyl alcohol, technical cetyl alcohol and technical oleyl alcohol; with a phenol or naphthol, e.g. phenol, b -naphthol, diisobutyl phenol and diisobutyl-cresols; with an aliphatic amine containing not less than 10 carbon atoms, e.g. technical dodecylamine and technical hexadecylamine; with an aromatic amine, e.g. a -naphthylamine; with aliphatic acid containing not less than 10 carbon atoms, e.g. stearic acid, oleic acid and acids derived from castor oil; with stearamide, oleoethanolamide and b -hydroxyethyl stearate. The examples relate to the condensates of di-iso-butylphenyl with 8 molecular proportions of ethylene oxide; technical cetyl alcohol with 17 mol. proportion of ethylene oxide; octyl cresol (obtained by reacting di-iso-butylene with a mixture of m- and p-cresols) with 10-20 mols. ethylene oxide and technical cetyl alcohol with 30 mols. ethylene oxide.ALSO:Ethylene oxide condensates of general formula Rz(CH2CH2O)xR1, where R is an alkyl radical, saturated or unsaturated, containing not less than 10 carbon atoms, or a cycloalkyl, aralkyl or an aryl radical, Z is -O-, -COO-, -NR11- or -CONR11-, wherein R11 is hydrogen or an alkyl radical, saturated or unsaturated, or a cycloalkyl or an aralkyl or an aryl radical or group (CH2.CH2.O)yR111 wherein R1 and R111 are hydrogen or an alkyl radical, the same or different and wherein x and y are integers, the same or different, said condensates being such that x+y or x (if y is absent) has a value of 1 to 30, are obtained according to conventional methods.
