Description

A kind of preparation technology of ε-epsilon-crystal form copper phthalocyanine
Technical field
The present invention relates to a kind of technology of preparing of pigment dyestuff new crystal, especially ε-epsilon-crystal form copper phthalocyanine (or C.I. pigment Blue 15: preparation technology 6).
Background technology
Copper phthalocyanine is known crystal formation more than five kinds, is referred to as α-crystal formation, beta-crystal, γ-crystal formation, δ-crystal formation and ε-epsilon-crystal form copper phthalocyanine, claims the copper phthalocyanine of R-crystal formation to come down to be equal to ε-crystal formation in the patent.Various different crystal forms copper phthalocyanines, show different physical property and color characteristics, such as: α-epsilon-crystal form copper phthalocyanine provides the ruddiness blue cast in low-melting ink vehicle, comprise astable α-crystal formation (C.I. pigment Blue 15) and stable alpha-crystal formation (C.I. pigment Blue 15: 1); The beta-crystal copper phthalocyanine provides the greenish blue tone, comprises anti-crystalline beta-crystal (C.I. pigment Blue 15: 3) with beta-crystal (the C.I. pigment Blue 15: 4) of the brilliant deflocculate of resistive connection; γ-epsilon-crystal form copper phthalocyanine, δ-epsilon-crystal form copper phthalocyanine provide the tone between α-epsilon-crystal form copper phthalocyanine, beta-crystal copper phthalocyanine.(the C.I. pigment Blue 15: 6) be the strongest crystal formation of ruddiness, it has excellent solvent resistance and heat-resistant stability than the more purified ruddiness blue cast of α-epsilon-crystal form copper phthalocyanine, γ-epsilon-crystal form copper phthalocyanine or δ-epsilon-crystal form copper phthalocyanine to ε-epsilon-crystal form copper phthalocyanine.
(the C.I. pigment Blue 15: 6) Technology mainly contains two types from existing patent report: a kind of technology is to be basic raw material with the phthalic nitrile to preparation ε-epsilon-crystal form copper phthalocyanine, and cost is higher; Another kind of technology then is that Tetra hydro Phthalic anhydride-urea is raw material, has that the technology cost is low, the yield advantages of higher.
Japan Toyo Ink company delivers patent (Japan Kokai 73-76925), by phthalic nitrile, cuprous chloride, urea and ammonium molybdate, in the oil of mirbane solvent, provide low chloro copper phthalocyanine, low chloro copper phthalocyanine 11g and 39g copper phthalocyanine be dissolved in 500 part 98% the sulfuric acid, precipitation, filtration, washing, drying in the water are with 100 parts in sodium-chlor, 25 parts of polyoxyethylene glycol, mediated 10 hours at 100-140 ℃, provide ε-epsilon-crystal form copper phthalocyanine. be to adopt to mediate in the polyethylene glycol medium to handle.
(Japan Kokai 73-59136) also reported employing copper phthalocyanine and its derivative in the Toyo Ink patent, (CuPc)-and CO-CH 2-NHC 2H 5, under strong shear action and sodium-chlor, ethylene glycol, grind at 80-160 ℃ and to mediate 10 hours, washing, drying provide ε-epsilon-crystal form copper phthalocyanine.
Big (the clear 57-141453 of Japanese ink house journal, 1982), in alkyl benzene solvent, interact, in the process of synthesizing copper phthalocyanine with the thing that organises, urea, the mantoquita that forms the phthalocyanine ring, add phthalocyanine derivates and a small amount of ε-epsilon-crystal form copper phthalocyanine, synthetic ε-epsilon-crystal form copper phthalocyanine.For example:
In potheater, add 120 parts of phthalimides, 104 parts of urea, 20.3 parts of cuprous chlorides, 0.8 part of ammonium molybdate, 300 parts of 2-ethylhexyl benzene, stir ε-epsilon-crystal form copper phthalocyanine and 12 parts of copper phthalocyanine derivative things with following structure of adding 12 parts down:
Figure GSA00000067507500021
Big Japanese ink company delivers the patent (clear 57-149358,1982) of the similar content of another piece, is reported in synthetic ε-epsilon-crystal form copper phthalocyanine in the alkyl benzene solvent.
In potheater, add phthalimide, part urea, cuprous chloride, ammonium molybdate, benzene derivative, stir the copper phthalocyanine derivative thing that adds ε-epsilon-crystal form copper phthalocyanine and following structure down:
Figure GSA00000067507500022
SUMITOMO CHEMICAL chemical company delivers patent (clear 64-1766,1989), at the organic solvent tetramethylene sulfone, with Tetra hydro Phthalic anhydride, urea, cuprous chloride, adds the copper phthalocyanine sulfonic acid of different sulfonation degree in reaction, directly synthetic ε-epsilon-crystal form copper phthalocyanine product.
In addition, also report prepared ε-epsilon-crystal form copper phthalocyanine of implementing the crystal conversion processing by some astable type copper phthalocyanine.For example: adopt δ-epsilon-crystal form copper phthalocyanine through grinding in German BASF (BASF) house journal (DE 2,210,072,1972), reflow treatment in butanone-2 prepares ε-epsilon-crystal form copper phthalocyanine product again.
BASF AG delivers patent (BP 1,411,880,1973), and report adopts instability mode crystal formations such as α-crystal formation, γ-crystal formation, δ-epsilon-crystal form copper phthalocyanine, prepares ε-epsilon-crystal form copper phthalocyanine product with the method for solvent treatment; The astable crystal formation that is adopted is with in the beta-crystal copper phthalocyanine vitriolization, the copper phthalocyanine vitriol hydrolysis that generates, obtain different astable epsilon-crystal form copper phthalocyanine products, when the dispersing apparatus with high shear force carries out ball milling, to there be a certain proportion of ε-epsilon-crystal form copper phthalocyanine to produce, wherein from the easiest formation of γ-epsilon-crystal form copper phthalocyanine ε-epsilon-crystal form copper phthalocyanine, so γ-epsilon-crystal form copper phthalocyanine is best suited at industrial preparation ε-epsilon-crystal form copper phthalocyanine; When ball milling, form α-crystal formation/ε-crystal formation mix products simultaneously usually, select specific solvent treatment again, finally all change ε-epsilon-crystal form copper phthalocyanine into.
Comprehensive above-mentioned existing Technology, no matter by direct synthetic method, or the method for crystal formation conversion, all there is some deficiency in final ε-epsilon-crystal form copper phthalocyanine product at application performance.Unsettled α-epsilon-crystal form copper phthalocyanine, in the crystal conversion course of processing as: adopt solvent treatment, ball-milling processing, when kneading is handled, be transformed into the copper phthalocyanine while of ε-crystal formation by α-epsilon-crystal form copper phthalocyanine, have a small amount of α-epsilon-crystal form copper phthalocyanine and be transformed into the beta-crystal copper phthalocyanine, thereby cause copper phthalocyanine product purity of color, tinctorial strength, solvent resistance, the heat-resistant stability of ε-crystal formation can all have certain deficiency.Copper phthalocyanine product technical indicator by detecting existing ε-crystal formation is as follows: contrast gradient is lower than 1440; Purity of color (saturation ratio) Δ C (detects with color measurement instrument) between 0.200-0.312; Glossiness is up to 38 (detecting with glossometer); Tinctorial strength and standard are than 100%; Solvent resistance (refluxing xylene) 98% heat-resistingly is not higher than 300 ℃.
In addition, development along with society, liquid-crystal display is developed to big liquid crystal panel aspect by original little liquid crystal panel, therefore requires purity of color, glossiness, the contrast gradient of used pigment further to improve, and the product of existing Technology can not satisfy the needs of development.
A kind of phthalocyanine blue 15:6 pigment prepared technology was once disclosed although number of patent application is 200610012573.1 application for a patent for invention.But, can not prepare stable phthalocyanine blue 15:6 pigment according to the record of this patent application specification.
