标题 :Precursors for synthesis of triphendioxazine dyestuffs
发明人：SCHWAIGER GUENTHER; SPRINGER HARTMUT; HELMLING WALTER
权利人:HOECHST AG
摘要:Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) ##STR1## in which: n is the number 0 or 1; n Y is the vinyl group or an ethyl group containing, in β-position, a substituent which can be eliminated by means of an alkali; n Q 1 and Q 2 both represent a benzotriazole radical which can also be additionally substituted in the benzene nucleus by alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, carboxy or sulfo; n B is --O--, --S--, --NH-- or --N(R')-- wherein R' is optionally substituted alkyl having 1 to 6 carbon atoms; n W 1 and W 2 both represent a divalent, optionally substituted aliphatic, cycloaliphatic, aliphatic-cycloaliphatic, araliphatic or aromatic-carbocyclic radical, it being possible for the aliphatic radicals to be interrupted by hetero groups --O--, --S--, --SO 2 --, --CO--, 1,4-piperidino, --NH-- and/or --N(R o )-- in which R o is optionally substituted alkyl having 1 to 6 carbon atoms or alkanoyl having 2 to 5 carbon atoms, and/or for aliphatic and aryl radicals to be attached to one another through such a hetero group; n R is hydrogen, alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, halogen, carboxyl or sulfo; n E is hydrogen, sulfo, carboxyl, a group --SO 2 --Y as defined above or an optionally substituted sulfonamide group; and n X 1 and X 2 are both hydrogen or halogen, cycloalkyl, alkoxy, aryloxy, aryl or another substituent; n and at least one carboxy, sulfo or sulfato group is present in the molecule (1), n and pre-products of those triphendioxazine compounds, of the general formula ##STR2## in which K is an amino or nitro group, Y' is β-hydroxyethyl or defined as for Y, W has one of the meanings of W 1 , and E' is hydrogen, sulfo, carboxy or a group of the formula --SO 2 --Y' defined above, or an optionally substituted sulfonamide group, and R, B and R* have the above meanings.

摘要:Two new organic compounds are disclosed, perfluorocyclohexane-1,4-dione and perfluorocyclohexene-1,4-dione, which are obtained concurrently or alternatively by reacting fluoranil with substantially pure anhydrous cobalt trifluoride. These compounds are clear, colorless liquids which are useful as monomers in the synthesis of thermally stable elastomeric polymers. Also disclosed is the dihydrate of said perfluorocyclohexane-1,4-dione, namely, octafluoro-1,1,4,4-cyclohexanetetraol. Another aspect of this invention is a series of polyethers formed by reacting said perfluorocyclohexane-1,4-dione with cesium fluoride and a cyclic or noncyclic aliphatic perhaloalkene having from 2 to 12 carbon atoms and a fluorine atom on at least each of the carbon atoms connected by the double bond, said polymer having as a repeating unit WHEREIN R is a divalent radical selected from the group consisting of -C=C- and -C = C- ANGLE ¦¦ CnX2n X2y+1CyCzX2z+1 WHEREIN X is a halogen selected from the group consisting of fluorine, chlorine, bromine, iodine, or any stable combination thereof within the same molecule; N IS AN INTEGER OF FROM 1 TO 4; Y IS AN INTEGER OF FROM 0 TO 10; AND Z IS AN INTEGER OF FROM 0 TO (10-Y).
