In addition, in the coating industry, it can be used as a coating additive to improve the film formation, adhesion, and weather resistance of coatings. Make the coating better protect the surface of the coated object, just like the development and application of various protective coatings in ancient times, so as to achieve the purpose of long-term protection of objects.

The production process of "2-bromobenzoic acid, 1-amino-9,10-dihydro-9,10-dioxo-4- (2,4,6-trimethylphenyl) amino-mono-potassium salt", according to the ancient classical style of "Tiangong Kaiwu", is described as follows:
The husband wants to make this "2-bromobenzoic acid, 1-amino-9,10-dihydro-9,10-dioxo-4- (2,4,6-trimethylphenyl) amino-mono-potassium salt", according to a certain order, using a specific method.
First, choose a pure starting material. In the preparation of "2-bromobenzoic acid", when bromine and benzoic acid are used as the basis, choose the appropriate reaction conditions. The amount of bromine, the temperature and pressure of the reaction need to be carefully controlled. Bromine, an active halogen element, reacts with benzoic acid in a mild environment. You can first place benzoic acid in a reactor, slowly add bromine, and at the same time, add a catalyst to promote the reaction speed, so that bromine can accurately replace the hydrogen atom at a specific position of benzoic acid to obtain pure "2-bromobenzoic acid".
times, it is the synthesis of "1-amino-9,10-dihydro-9,10-dioxo-4- (2,4,6-trimethylphenyl) amino-". Using related organic compounds as raw materials, it is formed through several steps of reaction. First, a compound containing an amino group reacts with another substance with a specific structure in an alkaline environment. The degree of alkalinity is related to the direction of the reaction. If the base is strong, it is easy to cause side reactions, and if the base is weak, the reaction is slow. When finding an appropriate degree, the two can be condensed smoothly, and then through oxidation and other steps, the structure of "9,10-dioxo" is formed. And when introducing "4- (2,4,6-trimethylphenyl) amino-", a suitable reaction path should be selected so that the phenyl group is accurately connected to the target position. After
, the above-obtained product is mixed with the potassium salt solution. The type and concentration of potassium salts also need to be carefully determined. The two are mixed, and after stirring and reacting for a certain period of time, potassium ions replace specific hydrogen atoms to form this "single potassium salt". Finally, after separation and purification, such as filtration, crystallization, washing and other steps, pure "2-bromobenzoic acid, 1-amino-9,10-dihydro-9,10-dioxo-4- (2,4,6-trimethylphenyl) amino-, monopotassium salt" are obtained. The whole process, the amount of material, the reaction environment, and the order of steps cannot be slightly different before this delicate product can be obtained.

"2-Cyano-1-amino-9,10-dihydro-9,10-dioxo-4- (2,4,6-trimethylphenylamino) benzoic acid, mono-potassium salt" The impact of this substance on the environment is quite complex.
Looking at its chemical structure, cyanide-containing compounds, if released in the natural environment, may be significantly toxic to water and soil organisms. Cyanide can inhibit the activity of many enzymes in organisms, especially cytochrome oxidase, hinder biological respiration, and cause biological cells to be unable to use oxygen effectively, thus posing a threat to the survival and reproduction of aquatic organisms such as fish, plankton, and soil microbial communities.
It contains amino and dioxo structures, and can participate in various chemical reactions in the environment. Amino groups have certain hydrophilicity and reactivity, or affect the distribution of compounds between soil and water, and or react with other substances in the environment. The dioxo structure makes the molecule have a certain polarity, which affects its migration and diffusion characteristics in the environmental medium.
Furthermore, the existence of trimethylphenyl groups, due to the stability and hydrophobicity of the benzene ring, or makes the compound difficult to be degraded by microorganisms, and persists in the environment. The substitution of methyl groups on the benzene ring changes the distribution of the electron cloud of the benzene ring, which affects the chemical reactivity and bioavailability of the compound.
As for the single potassium salt form, although potassium ions are common ions and generally have low toxicity in the environment, they may change the ionic strength and acidity and alkalinity of compounds in soil and water, and indirectly affect the chemical balance and biological community structure of the surrounding environment. For example, after changing the pH of the soil, it affects the nutrient availability in the soil and the absorption of nutrients by plant roots.
