| titleOfInvention | New dyes containing dihalopyrimidino groups |
| abstract | The invention comprises reactive dyes of formula D-(Z)m wherein dye is the chromophoric moiety of a dye containing or consisting of the radical of an azo, anthraquinone or phthalocyanine dye, Z is a dihalopyrimidine radical linked directly to a benzene radical of D which may contain a methyl or hydroxyl group and m is 1, 2 or 3 The dyes may be prepared by (a) condensing an amine of formula <FORM:1035779/C4-C5/1> wherein R is a hydrogen atom or a methyl or hydroxy group with a dye containing 1, 2 or 3 halogen atoms or -COCl or -SO2Cl groups or (b) condensing a compound of formula <FORM:1035779/C4-C5/2> wherein Y is a -COCl, -SO2Cl, -N=C=O or urethane group with a dye or dye intermediate containing 1, 2 or 3 acylatable amino groups and in the case of an intermediate effecting a further condensation reaction to form the dye. In examples the preparation of mono- and dis-azo, metallized azo, phthalocyanine and anthraquinone dyes is described.ALSO:The acid chloride of 4-(carboxyphenyl-2,6-dichloropyrimidine is prepared by dissolving the acid in o-dichlorobenzene and dimethylformamide and passing in phosgene. 4 - (31 - Nitrophenyl) - 2,6 - dichloropyrimidine is prepared by treating 4-phenyl-2,6-dichloropyrimidine in conc. sulphuric acid solution with fuming nitric acid: 2 - (31 - Nitrophenyl) - 4,6 - dichloropyrimidine and 2 - (41 - methyl - 31 - nitrophenyl) - 4,6 - dichloropyrimidine are similarly prepared. 4 - (31 - Aminophenyl) - 2,6 - dichloropyrimidine, 2 - (31 - aminophenyl) - 4,6 - dichloropyrimidine and 2 - (41 - methyl - 31 - aminophenyl) - 4, 6 - dichloropyrimidine are prepared by catalytic hydrogenation of the above nitro compounds. 1 - (21,61 - Dichloropyrimidyl - 41) - benzoylamino - 8 - naphthol - 3,6 - disulphonic acid is prepared by acylating H acid with the acid chloride described above; 2-(41,61-dichloropyrimidyl - 21) - benzoylamino - 5 - naphthol - 7 - sulphonic acid is similarly prepared. 2 - Phenyl - 4,6 - dichloropyrimidine is prepared by slowly adding tripropylamine to a mixture of phosphorus oxychloride and 2-phenyl-4,6-dihydroxypyrimidine followed by boiling; 2 - p - tolyl - 4,6 - dichloropyrimidine is similarly prepared. 4 - (31 - chlorosulphonyl) - phenyl - 2,6 - dihydroxypyrimidine is prepared by treating 4-phenyl-2,6-dichloropyrimidine with chlorosulphonic acid and further reaction of the product with phosgene yields 4-(31-chlorosulphonyl)-phenyl - 2,6 - dichloropyrimidine; 2 - (31 - chlorosulphonyl) - phenyl - 4 - hydroxy - 6 - chloropyrimidine and 2 - (31 - chlorosulphonyl)-phenyl-4, 6-dichloropyrimidine are similarly prepared. are similarly prepared |
