摘要:
Process for dyeing textile material with pigment dyes, which comprises1. pretreating the textile material with a polymer which consists wholly or partly of monomeric units of the formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen, (C.sub.1 -C.sub.22)alkyl which may be interrupted by --CO--NH-- or --NH--CO--, or C.sub.1 -C.sub.4 -hydroxyalkyl,R.sup.3 and R.sup.4 are each hydrogen or methyl, and Y.sup.- is a monovalent anion or one equivalent of a polyvalent anion,2. then dyeing with a pigment dye in the presence of a leveling or dispersing agent by the exhaust method and if necessary3. treating the dyeing in a liquor with a pigment binder and subsequently fixing it.This process makes it possible to dye textile material, in particular ready-made jeans garments, with pigment dyes by an exhaust method.

Triazolyl stilbene compounds of the formula ##STR1## wherein A is a benzene or naphthalene ring optionally substituted by non-chromophoric substituents and B is a substituted 1,2,4-oxdiazole (3) or 1,3,5-oxdiazole (2) group, as well as a procedure for their manufacture and their use as optical brighteners.
摘要:
Brighteners for detergents consisting of a mixture of 4,4'-bis-(2-morpholino-4-anilino-1,3,5-triazinylamino)-stilbene-2,2'-disulfonic acid-di-Na salt and from 5 to 50% by weight, calculated on said brightener, of another brightener of the formula ##STR1## in the above formula, M is an alkali metal cation, preferably sodium, X is a group of the formula --COR.sub.2 or --SO.sub.2 R.sub.3, R.sub.2 being C.sub.1 -C.sub.8 -alkyl and R.sub.3 being C.sub.1 -C.sub.5 -alkyl, C.sub.4 -C.sub.8 -cycloalkyl, phenyl or toluyl, Y is hydrogen or C.sub.1 -C.sub.5 -alkyl, A is C.sub.3 -C.sub.6 -alkylene, R.sub.1 is hydrogen, C.sub.1 -C.sub.5 -alkyl, C.sub.4 -C.sub.8 -cycloalkyl, or a group of the formula ##STR2## and Z is an anilino group, a chloroanilino group or a morpholino group. Said brightener mixtures are color-stable and do not show any green discoloration even after a prolonged storage in a moist atmosphere.
摘要:
Perfluoro-alkoxy propionic acid fluorides may be obtained by reacting hexafluoro-propene epoxide with a perfluoro-carboxylic fluoride in an aprotic polar solvent in the presence of a N,N,N', N'-tetrasubstituted diaminodifluoromethane as catalyst.The compounds obtained may be used as starting products for valuable perfluoro ethers which are highly inert towards heat or aggressive chemicals, such as fluorine.
摘要:
By reaction of a perfluoro vinyl ether with a perfluoro carbonic acid fluoride perfluorinated ketones of the formula R.sup.1 --O--CF(CF.sub.3)--CO--R.sup.2 with at least 13 carbon atoms may be obtained. These ketones may be used as inert solvents of high boiling point. The reaction is catalyzed by cesium fluoride and carried out in an aprotic polar solvent.
摘要:
By reacting tertiary amines carrying hydroxyethyl or 2-hydroxypropyl groups with hexafluoropropene in an aprotic solvent in the presence of a basic catalyst such as triethylamine the hexafluoropropyl ether of the starting compound containing the group ##STR1## with X = CH.sub.3 or H is obtained.
