Application of Cyanuric Chloride
Pesticide synthesis
In the market consumption structure of cyanuric chloride, s-triazine pesticides occupy an important position. In my country, about 70% of the demand for cyanuric chloride is used to synthesize triazine pesticides, and among the varieties of triazine pesticides, s-triazine herbicides are the main consumer. According to statistics, there are currently 9 varieties of triazine herbicides on the market, namely atrazine, terbutin, simazine, atrazine, promethazine, cyanoxazine, terbutin, xicaine, Triflufenacil and isoprene. Most of the s-triazine herbicides are mature products with relatively stable market sales.
In 2010, the global market sales of mestriazine herbicides reached US$603 million, of which atrazine reached US$370 million, followed by terbumin and promethazine, with sales of 70 million respectively. and $65 million. Although atrazine has been on the market for nearly 60 years and is affected by new herbicides, it will occupy a certain position in the future herbicide market due to its low toxicity and low cost of use. In addition, with the application and development of triazine herbicides in non-agricultural fields, some old varieties are also showing new vitality to a certain extent. Extends the life cycle of triazine herbicide products to a large extent. The main active monomer structure synthesized from cyanuric chloride is as follows:
Fluorescent whitening agent
In addition to herbicides, fluorescent whitening agents also play an important role in the cyanuric chloride industry chain, and with the improvement of people’s living standards, higher requirements for the demand and quality of fluorescent whitening agents are put forward. Fluorescent whitening agent mainly absorbs ultraviolet rays of wavelengths that are invisible to the naked eye in the sunlight, and then emits blue light or blue-violet light that is visible to the naked eye. , ink, photo paper, etc. are whiter, brighter and brighter.
At present, the fluorescent whitening agent products on the market mainly include stilbene, benzoxazole, coumarin, naphthalimide and pyrazoline, among which triazine is the most widely used. Stilbene type fluorescent whitening agent. In this type of product, the DSD acid and different substituent groups are linked together by cyanuric chloride. The varieties with commercial value that have been found so far include more than 50 kinds of bistriazine aminostilbene type fluorescent whitening agents such as VBU, VBA, CXT, BBU, etc., accounting for about 50% of the total fluorescent whitening agents, and about 90 of them. The varieties with more than % are water-soluble, not only low in price, but also in simple processing technology, and are widely recognized by the market.
In addition, there are coumarin products containing triazine group such as SFG, brightener 355, and improved triazine aminostilbene type brighteners BR, HL and other varieties, although the varieties are more than triazine group There are far fewer varieties of stilbene-type fluorescent whitening agents, but they have specific market applications due to their better performance.
Light Stabilizer
Light stabilizer is a kind of polymer material additive, which can improve the aging resistance of polymers by capturing free radicals to decompose peroxides and transfer excited state energy. It is usually obtained by connecting hindered amine with cyanuric chloride. At present, the best hindered amine light stabilizer is GW-944. Based on this structure, some light stabilizers with other structures are synthesized through the substitution of substituents. Studies have been carried out, such as the use of hindered amine light stabilizer monomers 4-hydroxy-tetramethylpiperidine or 4-amino-tetramethylpiperidine to modify the triazine ring to improve product performance, etc., which is also cyanuric chloride. An integral part of the market structure.
UV Absorber
Ultraviolet light absorber is a special kind of light stabilizer, mainly including benzophenones, benzotriazoles, triazines, etc. The ultraviolet absorber makes itself from the ground state to the excited state by absorbing ultraviolet light, and then gradually. It transitions back to the ground state and releases energy in the form of visible light or thermal radiation. This formula can reduce the free radical oxidation and reduction of the polymer material after being irradiated by ultraviolet light, so as to protect the appearance and appearance of the polymer material. Use for performance purposes.
Triazine UV absorbers are UV absorbers with the highest absorption efficiency developed in recent years. These products usually have phenolic hydroxyl groups, and the phenolic hydroxyl groups form intramolecular hydrogen bonds with the nitrogen atoms of the tricyclic ring. Through the formation of hydrogen bonds And break to achieve the purpose of absorbing ultraviolet light. Products are widely used in food and daily chemical packaging, textiles, fibers, plastics, coatings and other industries, especially in automotive coatings, the effect is far better than other types of UV absorbers. The synthesis of such compounds usually goes through at least one Grignard coupling and Friedel-Crafts alkylation to connect a phenolic hydroxyl-containing functional group on the triazine ring, and then different etherification modifications are used to obtain target products with different properties.
Other aspects
In addition to the above applications, cyanuric chloride is widely used in many other industries, such as synthetic reactive dye yellow 145, 167, 176, reactive dye red. Using cyanuric chloride and phenyl phosphinate as raw materials to synthesize various flame retardants such as triazine triphenyl phosphinate propyl ester, ethyl ester, and heavy metal scavenger TMT-3Na for soil remediation.
Preparation of Cyanuric Chloride
Sodium cyanide method
Most of the world’s advanced countries adopt the hydrocyanic acid process route, that is, liquid hydrocyanic acid and chlorine gas are used for gas-liquid reaction in the reactor, and the generated chlorine cyanide gas, after washing and rectification, enters the gaseous state with the catalyst. The cyanuric chloride gas is generated in the polymerization reactor of the fixed bed, and then enters the condenser to obtain the product, and the tail gas is discharged after treatment. There are three methods for preparing cyanuric chloride by mixing cyanuric chloride, liquid phase method, pressurization method and normal pressure gas phase method.
The liquid phase method is the original industrial method. Since the polymerization is carried out in the liquid phase, the reaction process is easy to control, but the product contains impurities such as tetramer and hexamer, which need to be refined, with low yield and high cost. Therefore, it has been widely used abroad. was eliminated. Pressurization method, the reaction temperature is as high as 450qC, the pressure is 1.98″9.8MPa, the reaction conditions are harsh, and the equipment is corroded strongly, and the post-processing of the product is more complicated, thus limiting its development.
Normal pressure gas phase method, mix fully dried hydrogen cyanide and chlorine in proportion (excessive chlorine), preheat, enter the polymerizer, use activated carbon (or silica gel, zeolite as the carrier of cupric chloride or ferrous chloride) As a catalyst, the polymerization reaction is carried out under the gas-phase condition of the controlled reaction temperature of 380°C, and the polymerized product is dried, cooled by cold air and crystallized to obtain the product. The synthesis of cyanogen chloride and the polymerization of cyanogen chloride are completed in one reactor or in two reactors. The latter can still recover part of the cyanogen chloride and return it to the polymerization reactor for polymerization, so the one-step method saves the cyanogen chloride purification process, thereby simplifying the equipment and shortening the reaction period, and the yield is above 86%.
The product quality, yield, production cost and other indicators of the atmospheric pressure method are better than other methods, and it is easy to produce on a large scale. Therefore, the atmospheric gas phase method has developed rapidly abroad and has now become the main synthesis route abroad. However, this method also has some shortcomings, such as high production temperature and certain dangers, and the product quality needs to be improved.
Sodium cyanide method
Using sodium cyanide and chlorine as raw materials, cyanogen chloride is synthesized, and then cyanuric chloride is prepared by gas-phase catalytic polymerization. In the specific process, the sodium cyanide solution sent from the tank area is prepared into a 15% aqueous solution, mixed with chlorine in proportion to enter the cyanogen chloride reactor through a special nozzle, and the cyanogen chloride monomer is generated. A separator is cooled and dehydrated, and then cooled and dehydrated by the second cooler and the second separator, and then enters the dryer for further dehydration and drying; then enters the polymerization reactor to generate gaseous cyanuric chloride, which is crystallized under cold air at 0.5 ° C to generate Powdered solid cyanuric chloride product.
The waste liquid of the chlorination reaction contains a certain amount of cyanogen chloride, which is heated to 90~100~C in the desorption kettle, and the decomposed cyanogen chloride monomer is returned to the reaction kettle, and the desorption waste liquid is sent to sewage treatment; After the absorption tower is treated with alkali absorption, it is sent to the chimney for discharge through the exhaust fan. The production technology of this route is mature and the product quality is good, but the pollution of the three wastes is serious, it is only suitable for small batch production, and the route is long, the yield is low and the production cost is high.
