At present, the varieties of dyes produced in China have reached more than 700 kinds, covering major dye categories
The advantages of industrial chain integration are obvious
The industrial structure is more reasonable
Production technology is constantly improving
Cleaner production problems have been solved
The tubular reactor is also applied in the production of dye intermediates and the continuous coupling of reactive dyes, which realizes continuous production and segmented temperature control, and has the characteristics of fast reaction speed, high conversion rate and high production efficiency, which greatly promotes the overall improvement
