摘要:
ANTHRAQUINONE REACTIVE DYESTUFFS USEFUL IN DYEING HYDROXYL AND NITROGEN-CONTAINING TEXTILES HAVING A NUCLEUS CONSISTING OF A 1-AMINO-2-SULFO-4-(SUBSTITUTED OR UNSUBSTITUTED) 4''-AMINO OR ALKYLENEAMINO, TRIAZINYL (SULFONANALINO) ANTHRAQUINONE. THE DYESTUFFS SHOW IMPROVED FASTNESS PROPERTIES.
摘要:
Process for the manufacture of 1-hydroxy-5-nitro-anthraquinone or 1-hydroxy-8-nitro-anthraquinone, characterised in that 1,5dinitro-anthraquinone or 1,8-dinitro-anthraquinone is reacted with alkaline compounds in polar aprotic solvents.
摘要:
A process of the preparation of fluoro substituted pyrimidines useful as lubricants, dyestuffs, pharamaceutical agents and pesticides which includes the isolated monofluoro-trichloro- and difluoro-dichloropyrimidines by reacting polyhalopyrimidines with hydrofluoric acid under increased temperature and pressure.
摘要:
Process for dyeing wool in a dyebath in the acid to neutral range wherein the dyestuff is a reactive dyestuff having the formula
IN WHICH D is the residue of an organic dyestuff, R is hydrogen or a lower alkyl, R1 is hydrogen or a substituent, R2 is hydrogen, halogen, substituted or unsubstituted alkyl, alkenyl, aralkyl, aryl, carboxcyclic acid ester, carboxcyclic acid amide, alkylsulphone, or arylsulphone; and F is fluoro. The dyed wool possesses excellent fastness to wet processing.
摘要:
The process for dyeing synthetic super polyamides with metal phthalocyanine sulfonic acids wherein the improvement comprises applying a phthalocyanine containing 2-3 sulfonic acid groups in the 4- or 5-position of their benzene nuclei to provide dyeings of improved light-fastness.
