applicant (patent):
Xingyu Chemical Plant, Luquan city, Hebei province
inventor:
National and provincial code:
CN130110
Abstract:
A preparation method of basic Violet 11:1, is the condensation reaction of M-hydroxy diethylaniline, phthalic anhydride and 98% sulfuric acid, the medium condition of alkali solution is that the pH value is between 11 and 12, the crystallization temperature of alkali solution is 40-60 ℃, and the crystal is washed with water to obtain the color base; The obtained color base is added to the ethanol solvent, magnesium oxide as a catalyst, with dimethyl sulfate as esterifying agent, under normal pressure reaction, after the completion of the reaction, heating ethanol evaporation until it is completed, adding hydrochloric acid and zinc chloride crystallization, drying. Its synthesis process is relatively simple, mild operating conditions, low cost.

CI NO 42555 - A new non-phenolic process for production of alkaline Violet
from VIP Journal Professional Edition
Author:
Abstract:
The production process route of basic Violet 5BN has two kinds of wet method and dry method, but it cannot be separated from phenol, so that the product contains a small amount of phenol, at the same time, a large amount of wastewater containing phenol, which is difficult to treat, is produced in the production. In particular, to the preparation of gentian violet (violet) pharmaceutical factory to bring the purification process is complex, low yield, large amount of secondary wastewater and other issues.
Key words:
