Claims
- 1. A process for the production of a metal phthalocyanine, which comprises heating phthalic anhydride or phthalimide, urea, metal salt and a catalyst in mixed solvents of chlorinated benzene and a linear hydrocarbon and wherein at least one compound selected from the group consisting of 1,8-diazabicyclo(5.4.0)-undecene, N,N-diethylaniline, N-butylaniline, aniline, N,N,N',N'-tetramethyl urea N,N,N',N'-tetramethyl thiourea, N-methyl-2-pyrrolidone, 1,3-dimethyl-2-imidazolidinone and dimethyl sulfoxide is further added in an amount of 0.01 to 0.6 mol per mole of the metal salt.
- 2. The process according to claim 1, wherein the chlorinated benzene is trichlorobenzene.
- 3. The process according to claim 1, wherein the linear hydrocarbon is a linear hydrocarbon having 10 to 19 carbon atoms.
- 4. The process according to claim 1, wherein the linear hydrocarbon is a linear hydrocarbon having 12 to 16 carbon atoms.
- 5. The process according to claim 1, wherein the mixed solvents contain 1 to 60% by weight, based on the weight of chlorinated benzene, of the linear hydrocarbon.
- 6. The process according to claim 1, wherein the mixed solvents contain 10 to 30% by weight, based on the weight of chlorinated benzene, of the linear hydrocarbon.
- 7. The process according to claim 1, wherein the phthalic anhydride or phthalimide, the urea, the metal salt and the catalyst are heated at a temperature between 160.degree. C. and 220.degree. C.
- 8. The process according to claim 1, wherein the phthalic anhydride or phthalimide, the urea, the metal salt and the catalyst are heated at a temperature between 170.degree. C. and 190.degree. C.
