High-performance black color paste and preparation method thereof
-
Paragraph 0049-0051, (2021/11/03)
The invention relates to the technical field of black pigments, in particular to a high-performance black color paste and a preparation method thereof. The preparation process does not need to be subjected to grinding treatment, can be highly dispersed in the low-melting-point amphiphilic solid, can effectively improve the workability and repeatability, and reduces the chromatic aberration 10% - 1000%. The preparation method disclosed by the invention causes the components to react and discolor in the kneading machine, finally obtains the black color paste, and is simple in preparation step, easy and convenient to operate, easy to prepare and good in application prospect.
A 3, 9 - perylene dicarboxylic acid preparation method
-
Paragraph 0024-0032, (2019/03/23)
The invention discloses a 3, 9 - perylene dicarboxylic acid of preparation method, specific step is ice-acetic acid in a solvent, in the dihydro e is obtained under the action of the sodium dichromate of 1, 8 - naphthalenedicarboxylic anhydride; 1, 8 - naphthalenedicarboxylic anhydride in saturated ammonia under the action of the acylation to obtain the 1, 8 - naphthalene asia amide; 1, 8 - naphthalene asia amide in potassium hydroxide and anhydrous sodium acetate manufacturing of the alkaline environment in the alkaline environment in C - C under high-temperature conditions obtained by coupling the 3, 4, 9, 10 - perylenetetracarboxylic acid diimide; 3, 4, 9, 10 - perylenetetracarboxylic acid diimide in under the action of the strong acid is converted into the 3, 4, 9, 10 - [...]; 3, 4, 9, 10 - [...] in microwave reactor in alkaline hydrolysis by the decarboxylation of 3, 9 - perylene dicarboxylic acid. The invention synthetic process more economic, environmental protection, high-efficient and simple.
