Abstract
Halogenated alkoxyphthalocyanine having a controlled grade of halogenation can be prepared by reacting a single compound or a mixture of phthalocyanine represented by the formula (1): ##STR1## wherein R.sup.1 is a substituted or unsubstituted alkyl group and may be the same or different, and Met is two hydrogen atoms, a divalent metal atom or a trivalent or tetravalent metal derivative, with 1 to 6 mole ratio of a halogenating agent at 0.degree. to 260.degree. C. in a solvent of from 1 to 1000 times by weight.
Claims12
A preparation process of a halogenated alkoxyphthalocyanine comprising reacting an alkoxyphthalocyanine represented by the formula (1):
- ##STR16## wherein R.sup.1 is a substituted or unsubstituted alkyl group and may be the same or different, and Met is two hydrogen atoms, a divalent metal atom, or a trivalent or tetravalent metal derivative, with a halogenating agent represented by the formula (2):
- X--Y (2)
- wherein X is a halogen atom and Y is a residue of the halogenating agent selected from the group consisting of a halogen atom, SO.sub.2 Cl, SOCl, FeCl.sub.2, PCl.sub.4, POCl.sub.2, CuBr and quaternary ammonium, to obtain the halogenated alkoxyphthalocyanine represented by the formula (3):
- ##STR17## wherein R.sup.1, Met and X are the same as R.sup.1 and Met of formula (1) and X of formula (2), respectively, and n is the number of substitution of X and is an integer of from 1 to 4, said X's being attached to benzene rings attached to the phthalocyanine nucleus.
