    Abstract: A process for wrinkleproofing cellulosic textiles comprises treating the textiles with a finish and drying the treated textiles, wherein the finish comprises one or more water-soluble or water-dispersible hydrophobically modified polyethyleneimines and/or polyvinylamines. Suitable hydrophobically modified polyethyleneimines are hydrophobically modified homopolymers of ethyleneimine, hydrophobically modified graft polymers of polyamidoamines or of polyvinylamines. Suitable hydrophobically modified polyvinylamines are hydrophobically modified at least partially hydrolyzed homo- or copolymers of N-vinylcarboxamides. The polyethyleneimines and polyvinylamines can be crosslinked by polyfunctional crosslinking compounds, quaternized and/or modified by reaction with alkylene oxides, dialkyl carbonates, alkylene carbonates and/or C 1 -C 4 -carboxylic acids. Suitable hydrophobicizing reagents are selected from the group consisting of long-chain linear or branched linear carboxylic acids, linear or branched alkyl halides, alkyl epoxides, alkylketene dimers, cyclic dicarboxylic anhydrides, alkyl isocyanates and chloroformic esters of fatty alcohols.

    Abstract: The invention relates to a method for isolating amines from aqueous solution s by means of continuous distillation of aqueous solutions of the amines according to a dual-pressure method for the rectification of aqueous solutio ns of amines forming an azeotrope with water, the composition of said azeotrope being pressure-dependent. The distillation is carried out in two columns und er different pressures. According to the inventive method, a) the pressure in t he second column is set at least 0.5 bar higher than the pressure in the first column, b) the aqueous amine solution is supplied to the first column in a side stream, and water and parts which boil at a higher temperature than the amines or are non-volatile are exfiltrated out of the bottom of the column, c) a mixture of amine and water is removed at the head of the first column and is guided into the second column in a side stream, d) an azeotrope of water and amine is removed at the head of the second column and is redirected into the first column, and e) the purified amines are extracted at the bottom of the second column.
