A method for producing a novel phthalocyanine compound which excels in yield and purity, allows no introduction of a chlorine atom into the phthalocyanine skeleton, and possesses relatively bulky substituents is provided.
This method is characterized by causing an orthophthalonitrile compound having a substituent exhibiting smaller σp values than σm values in the Hammett's rule to react with a metal oxide in the presence of a compound forming in the aqueous solution thereof at 25°C an acid or conjugate acid having a dissociation index pKa (the logarithmic value of the reciprocal of the dissociation constant of the acid or conjugate acid) of not more than 7.0.
本发明提供了一种生产新型酞菁化合物的方法,该方法产量高、纯度高,不允许在酞菁骨架中引入氯原子,并具有相对笨重的取代基。
该方法的特点是,在 25°C 时,在其水溶液中形成的酸或共轭酸的化合物存在下,使具有取代基的 σp 值小于哈密特规则中的σm 值的邻苯二甲腈化合物与金属氧化物反应,该酸或共轭酸的离解指数 pKa(酸或共轭酸的离解常数倒数的对数值)不大于 7.0。
