| titleOfInvention | The pollution-free preparation process of direct fast red BNL dyestuff |
| abstract | The present invention relates to a kind of pollution-free preparation process of direct fast red BNL dyestuff, step comprises: formation solution is dissolved in cyanuric chloride, BHK acid respectively, after both being carried out three condensations, be hydrolyzed, by Ortho Anisidine-4-sulfonic acid diazotization adding aniline, by diazo liquid within 1 hour, adding in the hydrolyzed solution that (7) step of being down to 10 DEG C obtain, pH=8.5 is adjusted, coupled reaction 2 hours, t=50-18 DEG C with soda ash, left back spraying dry, obtains dyestuff finished product.The present invention adds reactive emulsifier EleminolJS-2 or JS-C when Fast Red B base dissolves, and improves speed of reaction, adds the dissolution rate of cyanuric chloride, save ice, be reduced to present 1000kg by the 2000kg of raw material, reduce the consumption of ice, reduce energy consumption. |
