Abstract

Abstract 892,167. Aqueous polyalkylene polyamine dispersions. CIBA Ltd. June 15, 1960 [June 16, 1959], No. 21067/60. Class 1(1) [Also in Groups IV(b) and IV(c)] Aqueous dispersions of compounds of formula in which A represents an alkylene radical containing 2 or 3 carbon atoms, K an aliphatic hydrocarbon residue containing 13 to 21 carbon atoms and m and n are whole numbers being at most 3 and 2 respectively are used to treat textile materials there being present at least partially a compound in which n=2. In an example an aqueous solution containing an adduct of ethylene oxide and hydroabietyl alcohol, an adduct of ethylene oxide and oleyl alcohol and a condensation product neutralized with sodium hydroxide solution of naphthalene sulphamic acid and formaldehyde is heated and stirred in an open vessel. To this solution is then added aqueous ammonia and a melt consisting of ethylene glycol monoethyl ether, stearic acid and the condensation product consisting of diethylene triamine and stearic acid, the rate of stirring increasing during addition until a smooth dispersion is obtained. The dispersion is diluted with hot water homogenized and cooled. Other examples describe the preparation of dispersions as above but containing condensation products from (1) diethylene triamine and myristic, palmitic or behenic acids instead of stearic acid and (2) stearic acid and triethylene tetramine, or tetraethylene pentamine instead of diethylene triamine. The dispersions may contain solvents in addition to water, e.g. xylene, decalin, chlorobenzene, o-dichlorobenzene, benzyl chloride, trichloroethylene and mono- and diethylene glycol monoethyl ether. As non-ionic dispersants the dispersions may contain adducts of ethylene oxide with (1) oleyl alcohol (2) oleylamine (3) hydroabietyl alcohol and (4) hydrogenated abietylamine. Alternatively the dispersions may contain an adduct of ethylene oxide and hydroabietyl alcohol cross linked with (1) hexamethylene drisocyanate or (2) diphenyl methane drisocyanate or an adduct of ethylene oxide and oleyl alcohol cross linked with hexamethylene drisocyanate.
