A method for producing copper phthalocyanine, which comprises heating and reacting phthalic acid or a phthalic acid derivative, urea or a urea derivative, and a copper compound, using molybdenum or a molybdenum compound as a catalyst, in the presence or absence of an inert organic solvent, wherein at least one compound selected from the group consisting of an aromatic dithiol compound of the following formula (I), a saturated aliphatic dithiol compound of the following formula (II), and their precursors, or at least one compound selected from the group consisting of a ruthenium compound and an osmium compound, is added to the reaction system:
CmH2m-xRx(SH)₂ (II)
wherein ring A in the formula (I) is a 6-membered single carbon ring or polycyclic condensed carbon ring aromatic compound, R for Rn in the formula (I) or for Rx in the formula (II) is a mercapto group (-SH), a substituted mercapto group (-SR' wherein R' is a substituent inert in the reaction system), or a substituent substantially inert in the reaction system, m is an integer of from 2 to 4, and n and x are optional integers of from 0 to the maximum number of substitutable positions of the respective compounds other than the positions for the mercapto groups (-SH) (when n and x are 0, the respective formulas represent unsubstituted dithiol compounds).
一种生产铜酞菁的方法,包括在有或无惰性有机溶剂的条件下,以钼或钼化合物为催化剂,使邻苯二甲酸或邻苯二甲酸衍生物、尿素或尿素衍生物和铜化合物加热反应、其中在反应体系中加入至少一种选自由下式(I)的芳香族二硫醇化合物、下式(II)的饱和脂肪族二硫醇化合物及其前体组成的组中的化合物,或至少一种选自由钌化合物和锇化合物组成的组中的化合物:
CmH2m-xRx(SH)₂ (II)
其中式(I)中的环 A 是 6 元单碳环或多环缩合碳环芳香化合物,式(I)中的 Rn 或式(II)中的 Rx 是巯基(-SH)、取代的巯基(-SR',其中 R' 是反应体系中的惰性取代基)、或在反应体系中基本惰性的取代基,m 为 2 至 4 的整数,n 和 x 为 0 至各自化合物中除巯基(-SH)位置以外的最大可取代位置数的任选整数(当 n 和 x 为 0 时,各式表示未取代的二硫醇化合物)。
