摘要:
Compounds of the formula ##STR1## wherein R represents cycloalkyl or the ##STR2## group wherein R.sub.1 and R.sub.2 denote alkyl and Y denotes hydrogen, chlorine, bromine, amino, alkylamino, cycloalkylamino, aralkylamino, arylamino, acylamino or arylmercapto, with the proviso that the nitro group is in the 5- or 8-position of the anthraquinone nucleus if Y denotes hydrogenAs well as their production and their use for the dyeing of synthetic fibres.
摘要:
The invention relates to the preparation of partially known anthraquinone compounds of the formula ##STR1## wherein Z.sub.1 represents an optionally substituted hydrocarbon radical,Z.sub.2 represents hydrogen or alkyl, one X represents a chlorine atom and the other X denotes a hydrogen atom, by subjecting technical chloroanthraquinone mixtures to a fractional vacuum distillation and reacting the 1,6(1,7)-dichloranthraquinone fraction thereby obtained with amines of the formula HNZ.sub.1 Z.sub.2.Moreover the invention relates to novel compounds of the above formula wherein Z.sub.2 is H and Z.sub.1 is alkyl, alkenyl, aralkyl or cycloalkyl. They are good dyestuffs for synthetic fibres or dyestuff intermediates.
摘要:
The invention relates to a process for the preparation of water-insoluble chlorine-containing diaminodihydroxyanthraquinone dyestuffs. The process consists in that 2,8-dichloro-1,5-dinitroanthraquinone and/or 2,5-dichloro-1,8-dinitroanthraquinone is warmed with sulphur in concentrated sulphuric acid having a maximum SO.sub.3 content of 20% - possibly in the presence of boric acid - the resulting compounds are, if appropriate, post-halogenated and/or alkylated, preferably in the same reaction batch.The main advantage of this process is that it starts from 1,6- and/or 1,7-dichloroanthraquinone, for which there was hitherto no industrial use, but which unavoidably also arise during the synthesis 1,5- and 1,8-dichloroanthraquinones.
摘要:
Compounds of formula ##SPC1##Wherein R.sub.1 and R.sub.2 independently of one another denote optionally substituted alkyl radicals with 1-3 C atoms and R.sub.3 represents hydrogen or an optionally substituted alkyl radical with 1-5 C atoms, as well as compounds of the formula ##SPC2##Wherein R.sub.4 represents an alkyl group which is optionally substituted by hydroxyl or alkoxy groups, and R.sub.5 and R.sub.6 represent hydrogen or an amino group which is monosubstituted or disubstituted by a straight-chain alkyl group or a cycloalkyl group, with the proviso that R.sub.5 and R.sub.6 do not simultaneously represent hydrogen, and processes for their production.
摘要:
Dyestuffs which contain sulphonic acid groups and correspond to the formula ##SPC1##In which R.sub.1 and R.sub.2 denote lower alkyl radicals with 1 - 3 carbon atoms, which may be substituted; A means an optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical; n stands for 0, 1 or 2; and R.sub.4 denotes a sulphonic acid group when n = 0 and denotes hydrogen or a sulphonic acid when n = 1 or 2.The dyestuffs are eminently suitable for the dyeing and printing of natural and synthetic polyamide fiber materials.
摘要:
Reactive dyestuffs are disclosed having the formula ##STR1## in which D is the radical of an organic nonanthraquinoid dyestuff; R is hydrogen or a lower alkyl; R.sub.1 is amino or substrated amino with substituents attached by a single bond, optionally etherified hydroxy, optionally etherified mercapto or an optionally substituted hydrocarbon radical; Q is an alkylene, aralkylene, arylene, --CO-- or --SO-- which is directly linked to a carbon atom of the ring of the dyestuff D; n is the number 0 or 1 and F is a fluoro substituent. The group --N(R) is directly linked to a carbon atom of the triazine ring and on the other side, the group --N(R) is linked to a carbon atom of the ring of the dyestuff D either directly (if n = 0) or (if n = 1) via one of the bridge members mentioned above. These dyestuffs are primarily suitable for dyeing of textile materials containing hydroxyl or nitrogen such as natural and regenerated cellulose, wood silk, polyamide and polyurethane. The fastness properties, particularly wet fastness, are excellent.

Dyestuffs are disclosed having the formula ##STR1## in which W is a reactive radical;D is the radical of an organic dyestuff;X.sub.1 is hydrogen or alkyl;X.sub.2 and X.sub.3 are hydrogen, alkyl, cycloalkyl, aralkyl or aryl; or X.sub.2 and X.sub.3 together are alkylene;Alkylene is C.sub.1 -C.sub.6 -alkylene or cycloalkylene; and n is 0 or 1.The dyestuffs are used in the dyeing of textile materials containing hydroxyl groups and nitrogen, especially natural and regenerated cellulose, wool, silk, synthetic polyamide fibers and synthetic polyurethane. The dyeings obtained are, in general, distinguished by good to very good fastness properties, especially by excellent wet fastness.
