Cuprous Chloride & Ammonium Molybdate in CuPc Pigments
Most copper phthalocyanine (CuPc) pigment is made by heating phthalic anhydride, urea, a copper source, and a small amount of catalyst together in a solvent. Cuprous chloride usually supplies the copper. Ammonium molybdate drives the reaction that closes the phthalocyanine ring. Together, they turn a handful of inexpensive raw materials into the blue and green […]
