Abstract

1523308 Polyether carbamates; methylolated carbamates; textile treating solutions BASF AG 17 Dec 1975 [18 Dec 1974] 51567/75 Heading C3R [Also in Division C2] Carbamates of the formula wherein R<1> is an aliphatic, cycloaliphatic or araliphatic radical which may be interrupted by one or more -CO-O-, -CO-NH- and/or -O- radicals, or R<1> is a NH2CO- or phenyl group or when (m is an integer) a hydrogen atom, R<2> is an aliphatic radical of at least 2 carbon atoms which is optionally interrupted by one or more -CO-O-, -CO-NH and/or -O- radicals, or it is an (-CHR<3>-)n radical, R<3> being a cycloaliphatic, araliphatic or aromatic radical and n being from 2 to 6, and m is 0 or an integer, are obtained by reacting the correspond. ing hydroxy compounds of the formula with urea in the presence of ion-exchangers containing nickel. An example illustrates the preparation of the carbamate The nickel-containing ion-exchanger may be obtained by treating a cation exchanger, after it had been standing in water, with 10% hydrochloric acid, washing the treated resin with water until neutral and treating the washed resin with nickel sulphate. The carbamates may be methylolated and used to treat cotton fabric, with MgCl2 as catalyst.
