Title: Photographic material for the silver dyestuff bleaching method
IPC: C09B43/16
Filed: 1963-02-22
Abstract: The Specification refers to disago dyes of the general formula <FORM:1015025/C4-C5/1> <FORM:1015025/C4-C5/2> wherein R1, R11, R2 and R12 are benzene or naphthalene residues, R2 and R12 being bound to the azo and amino groups in para position, X is a 1; 3; 5-triazine residue bound in the 2- and 4-positions to the amino groups, and n is 1 or 2, the molecule as a whole containing at least 3 sulphonic acid groups.  The dyes are prepared by diazotizing an amine R1NH2, coupling the diazonium compound with an amine R2NH2, and acylating the product with m- or p-nitrobenzoyl chloride to give a monoazo dye of the formula R1-N = N-R2-NG-CO-C6H4-NO2. The nitro group is then reduced to the corresponding amine and then two mols. of the amine are condensed with 1 mol. of cyanuric chloride to give a symmetrical dye, or one mol. of the amine is first condensed with 1 mol. of cyanuric chloride and the product condensed with 1 mol. of a different amine or with the same or different amine R11-N = N-R12-NH2 which has not been subjected to the treatment with nitrobenzoyl chloride.  The chlorine atom in the 6-position of the triazine ring X may then be replaced by other groups by treatment with sodium hydroxide (to give an OH group), with g -methyoxy-propylamine to give a g -methoxy-propylamino group or with ethanolamine, b -amino-ethane sulphonic acid, diethylamine, monomethylamine, 3 - sulpho - aniline, 4 - aminobenzoic acid or ammonia.  The residues R1 and R11 may each have one or more sulphonic acid substituent and in addition an alkyl, alkoxy, chloro or, in one example, a benzoylamino, substituent.  The residues R2 and R12 may be benzene residues free of sulphonic acid groups but may contain alkyl, alkoxyl, acetamino or methylsulphonylamino substituents.

Specified aromatic hydrocarbons are naphthalene, diethylbenzene, ethylnaphthalenes, diphenyl-methane and -ethane and homologues thereof and anthracene oil.  During the reaction further olefin may be added, and also super-atmospheric pressure may be used. After the reaction the mixture is allowed to settle and the upper layer decanted and distilled.  The lighter fractions may be used as diluents in a further olefin polymerization. Treatment of the used aluminium chloride complex gives an oil having drying properties.  Specification 610,813, [Group IV (b)], is referred to.ALSO:Lubricating oils are obtained by reacting an aromatic hydrocarbon in the presence of aluminium chloride at a temperature not below 20 DEG  C. and not substantially higher than 80 DEG  C. and with the aid of cooling, with petroleum obtained by fractional distillation of the products obtained by polymerizing an olefin in the presence of aluminium chloride.
