The preparation and application of substituted Phthalocyanine
Abstract: This study is for the company’s existing copper phthalocyanine (A) and n-hydroxy-methyl phenyl azo naphthalene-carboxamide (B) development of applied research projects. A and B are produced by two commercial products, A is a blue pigment,B is a red pigment.They are not only organic solvent resistance, acid and alkali, excellent corrosion resistance and light resistance, weather resistance, temperature resistance is also very good, already widely used in paints, plastics, inks and other industries; Indole carbon-Ching has large molar extinction coefficient, good, light and fluorescence properties and high thermal stability, will replace the indole into the molecular structure of A and B, can get the application prospect of new paint. After Vilsmeier reaction to a raw materials, preparation of acid copper phthalocyanine(C); With trimethyl-substituted indoline as raw material, and iodide salts get indoline salts (D), D condensation reactions with the B and C are respectively 1-ethyl- -3,3-dimethyl-2-(β-n-phenyl-2-hydroxy-4-of for mamide styryl-azo naphthalene)-3H-indole iodide(E) and 1-ethyl-3,3-dimethyl -2-(β-phthalocyanine copper vinyl) -3H-indole iodide (F). Focused its investigation on compound preparation of C and B, C with active methylene compounds indoline D feasibility. Experimental results show that: Phthalocyanine through Vilsmeier reaction of Carbonyl get compound C, Through a condensation reaction of aromatic aldehyde with active methylene compounds are chemical compounds E, Compound F preparation is difficult to achieve under the existing conditions.
