| Use | metal-free phthalocyanine gives a green-blue tone, and its industrial value is not large, but it was applied as a green-blue variety in the early years, and then it was replaced by β-type CuPc. Of the five crystal forms, only the α-form has a certain value, like the α-CuPc, which is converted into stronger green light in an organic solvent, and at the same time, easy dispersion and anti-flocculation are not ideal. The pigment is mainly used in acrylic resin metal decorative paint, can also be used for plastic coloring, but the thermal stability is not as good as α-or β-CuPc. |

C.I.Pigment Blue 16 - Uses and synthesis methods
introduction
phthalocyanine, also known as phthalocyanine and phthalocyanine, a kind of dark compound, similar in structure to porphyrin ring (or porphyrin complex, porphyrin), is a dye composed of four pyrrole nuclei and has a porphyrin ring structure. According to molecular orbital theory, the conjugated system with this structure is very stable. Phthalocyanine has been developed as a blue to green pigment with the highest fastness. Later, dyes with excellent performance were derived by various methods. It is divided into metal phthalocyanine and metal-free phthalocyanine. There are two types of metal phthalocyanines: one type contains copper, iron, zinc, cobalt, platinum, etc. The atomic radius is close to the radius of the central gap of the phthalocyanine molecule. These metals are combined with two nitrogen atoms in the four nitrogen atoms by atomic bonds, and are combined with the other two nitrogen atoms by valence bonds. This type is called stable type; the other type is sodium, potassium, barium, cadmium, magnesium, lead, etc., the atomic radius of the metal atom is too long to form a valence bond with phthalocyanine, and can only be combined with two nitrogen atoms in an atomic chain to form a salt. The former is treated with concentrated sulfuric acid, and the metal is not removed; it is slightly soluble in organic solvents; it can be sublimated under high temperature vacuum. The latter, in case of acid or water, the metal is easily removed; it is insoluble in organic solvents; it does not sublimate under high temperature vacuum. The four benzene rings in the phthalocyanine molecule are more prone to substitution reactions and easy to sulfonate. Dyes derived from phthalocyanine include direct dyes, sulfide dyes, vat dyes, phthalocyanine near dyes (phthalocyanine), special water-soluble dyes and reactive dyes. Metal phthalocyanine is prepared by co-heating phthalic anhydride or phthalonitrile with metal or metal salt.
application
Phthalocyanine is an important organic pigment. Its chromatography is mainly blue and green. Bright color and strong coloring power. It has excellent weather resistance, heat resistance, solvent resistance, acid resistance and alkali resistance. It is widely used in paint, ink, plastic coloring, paint printing, synthetic fiber puree coloring, etc.
