| abstract | 1290922 Preparing metal phthalocyanines DAINICHISEIKA COLOR & CHEMICALS MFG CO Ltd 13 Feb 1970 7136/70 Heading C4P Metal phthalocyanines are prepared by condensing an o-dinitrile of the general formula wherein A forms an aryl or a heterocyclic radical, X is H, halogen, nitro, amino, sulphonic or carboxylic acid group, alkyl or alkoxy and n is an integer from 1 to 4, and a metal or a metal compound capable of providing the central metal atom of a phthalocyanine pigment at below 100‹ C. in presence of an alkaline substance which is an hydroxide, oxide, peroxide or carbonate of an alkali metal or alkaline earth metal and a hydrophilic organic solvent containing an hydroxy group. A copper phthalocyanine, produced by the above method and having an X-ray crystallographic pattern with peaks at 6À8, 9À8, 15À6, 24À8, 25À2, 25À6, 26À8 of 2#(CuKα/Ni) is claimed per se. The hydrophilic organic solvents used include C 1 -C 4 alcohols, ethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol, methyl and ethyl Cellosolve diethylene-glycol ethyl ether, phenol and o-, m- and p-cresols. The o-dicyano compound is preferably of the benzene, naphthalene, anthracene or phenanthrene series and the metals used include Co, Cu, Ni, Zn, Sn, Fe, Pd, Cr, Pt, Mn, V and Mo and their compounds. In preferred embodiments (i) a hydrophobic organic solvent may replace part of the hydrophilic organic solvent, e.g. benzene, toluene, xylene, naphthalene, biphenyl, chlorobenzenes and naphthalenes, nitrobenzene, chloronitrobenzene, and nitrotoluene; and the condensation may take place in presence of (ii) an inorganic or organic ammonium salt, (iii) an acid, (iv) a surfactant, (v) a compound forming a complex with the metal atom. |
