The development of cyanuric chloride in my country in the future

Experts believe that the development of cyanuric chloride in my country should focus on the following five aspects:

1. Speed up the research and development of new technologies

At present, cyanuric chloride industrial production technologies mainly include sodium cyanide method and hydrocyanic acid method. Cyanuric chloride in my country is mainly produced by the sodium cyanide method, which has a relatively high cost; while abroad, it is mainly produced by the hydrocyanic acid method, which is more technologically advanced, economical, and easier to scale. Therefore, the primary task for the development of cyanuric chloride in my country is to upgrade technology. Scientific research institutions should join hands with manufacturers to overcome the technical difficulties of cyanuric chloride production by the hydrocyanic acid method as soon as possible. Even if all the problems cannot be solved at the moment, they can also take the road of combining introduction and self-development to make the hydrocyanic acid method synthesize trimer. The cyanogen chloride route realizes industrial production as soon as possible in our country.

2. Accelerate the pace of industrial adjustment

Cyanuric chloride is an important intermediate and is in great demand in the domestic market. However, due to blind construction in the past few years, the domestic supply of cyanuric chloride has exceeded demand. Therefore, the scale of production should be strictly controlled, and the construction of devices with small production capacity (under 1,000 tons/year), large emissions of'three wastes', and backward technology should be prohibited, and new capacity should be controlled. It is necessary to adjust the industrial structure as soon as possible, and eliminate small-scale installations through reorganization and competition.

3. Intensify the development of downstream products and seek new uses

Cyanuric chloride has many industrial uses. Compared with foreign countries, my country's current application range is still relatively narrow, and its application in many fields is still blank. In the future, we will focus on increasing the research and development of cyanuric chloride downstream products, and expand its application range and application volume. In the dye industry, it is necessary to speed up the research and development of new varieties of reactive dyes using cyanuric chloride as raw materials; in the pesticide industry, currently there are only 6-7 types of s-triazine herbicides synthesized using cyanuric chloride as raw materials in China. There are as many as 20 kinds, and the development of other s-triazine herbicides should be accelerated. In addition, the application of cyanuric chloride in plastics, rubber, medicine and other fields should also be actively explored. Production enterprises with conditions may consider launching the downstream products of cyanuric chloride, or jointly develop them with manufacturers of downstream products of cyanuric chloride.

Fourth, improve the existing production model

Since sodium cyanide (or hydrocyanic acid) and chlorine are not easy to store and transport as the raw materials required for the production of cyanuric chloride, the expansion of production scale in the future should rely on the advantages of raw materials, such as in chlor-alkali enterprises close to large-scale acrylonitrile plants. , The use of its own chlorine resources and acrylonitrile by-product hydrocyanic acid to build a cyanuric chloride plant can effectively use resource advantages, reduce investment risks, reduce production costs, and improve competitiveness.

5. Actively expand exports

In the next few years, the oversupply situation of my country's cyanuric chloride market will become more prominent. Therefore, in addition to continuously exploring new uses, domestic companies should focus on the international market and actively expand exports to ease the pressure on the domestic market.
