| titleOfInvention | Process for the production of coupling phthalocyanine derivatives |
| abstract | 1 - (41 - Aminophenyl) - 3 - methyl - pyrazolyl - (5)-ethylcarbonate is made by reduction of the corresponding 41-nitrophenyl derivative prepared by reacting 1-(41-nitrophenyl)-3-methyl-pyrazolone-(5) with ethyl chloroformate. The benzene and p-toluene sulphuric acid esters of 1-(31-aminophenyl) - 3 - methyl - 5 - pyrazolone are made by reducing the corresponding 31-nitrophenyl derivatives made by reacting 1-(31-nitrophenyl)-3-methyl-pyrazolone-(5) with benzene or p-toluene sulphonic acid chlorides respectively. The benzene sulphonic acid ester of 1-(41 amino-phenyl)-3-methyl-5-pyrazolone is made by reducing the corresponding 41-nitrophenyl derivative made by reacting benzene sulphonyl chloride with 1-(41-nitrophenyl)-3-methyl-pyrazone. The benzene sulphonic acid esters of 1-(41-ethyl-, -propyl- or -benzyl-aminophenyl)-3-methyl-5-pyrazolone are made by reducing a mixture of 1 - (41 - aminophenyl) - 3 - methyl - pyrazolone - 5 - benzene sulphonic acid ester and acetaldehyde, propionaldehydes or benzaldehyde respectively with hydrogen and Raney nickel. The benzene sulphonic acid ester of 1-(31-ethylaminophenyl)-3-methyl-5-pyrazolone is similarly prepared from the 31-aminophenyl derivative and acetaldehyde. The benzene sulphonic acid esters of 1-[41- or 31-(311-aminobenzoyl)-aminophenyl] - 3 - methyl -5-pyrazolone are made by reduction of the corresponding 311-nitrobenzoyl derivatives which are made by reacting 3-nitrobenzoyl chloride with the benzene sulphonic acid esters of 1-(31 - or 41 - aminophenyl) - 3 - methyl - 5 - pyrazolone. 3 - Aminobenzoyl-acetic acid anilide - O - benzene sulphonic acid ester is made by reduction of the corresponding 3-nitrobenzoyl derivative which is made by reacting benzene sulphonyl chloride with 3-nitro-benzoyl-acetic acid anilide. 4-Aminophenol-benzene sulphonic acid ester is made by the hydrolysis of 4-acetylaminophenol-benzene sulphonic acid ester prepared by reacting 4-acetylaminophenol with benzene sulphonyl chloride.ALSO:The invention comprises compounds of the formula: Pc-(R-R1)n where Pc is a phthalocyanine radical, R is -SO2- or -CO-, R1 is an amino-containing radical of the benzene, naphthalene, pyrazolone or acylacetic acid arylamide series linked to R via the amino group and containing an esterified hydroxyl group and, in an adjacent position, a carbon atom capable of coupling with a diazonium compound after saponification of the esterified hydroxyl group and n is 1-4. The compounds are made by reacting a phthalocyanine sulphonic or carboxylic acid halide containing 1-4 acid halide groups with an appropriate primary or secondary amine of the benzene, naphthalene, pyrazolone or acylacetic acid arylamide series containing an esterified hydroxyl group. The esters and their saponification products dye and print cotton, spin-dye synthetic fibres and dye plastics. The saponification products are also coupled to form azo dyestuffs in substance or on the fibre. |
