METHOD OF PREPARING ALKOXYPHTHALOCYANINE |
摘要 |
There is here disclosed a method for preparing an alkoxyphthalocyanine represented by the formula (1): (see formula I) wherein each of Rs is independently a secondary alkyl group having 3 to 20 carbon atoms, Met is a divalent metal atom or an oxy metal, and the substitution positions of -ORs are the 1- or 4-position, the 5- or 8-position, the 9- or 12 position, and the 13- or 16-position, which comprises the steps of heating a mixture of 3-alkoxyphthalonitrile and an organic base in an alcohol to 90-120.degree.C, adding a metal derivative at the same temperature, and then carrying out reaction, or alternatively the step of reacting a mixture of a 1,3-diimino-4-alkoxyisoindoline and a metal derivative in the presence or absence of an organic base in an aliphatic alcohol having 6 or more carbon atoms. In addition, the ratio of isomers of the alkoxyphthalocyanine can be controlled by regulating the addition time of the organic base.
