METHOD OF FINE-CRYSTALLINE COPPER PHTHALOCYANINE PRODUCING Russian patent published in 1998 - IPC

Abstract RU 2104995 C1

FIELD: chemical technology. SUBSTANCE: synthesis of copper phthalocyanine is carried out at 20-40 C in N,N-dimethylformamide by interaction of 1,3-diiminoisoindoline with ultradispersed copper powder (surface above 30 m2/g) obtained by electric conductor explosion in nitrogen atmosphere. Ultradispersed copper powder and 1,3-diiminoisoindoline were mixed as dry substances. The end product can be used as dye, sensor agent, component of photosensitive layers. EFFECT: improved method of synthesis.
