Maintenance of Methyl Ethyl Carbonate, Electronic Cleaning Fluid

Tetramethylammonium hydroxide (TMAH) produced from dimethyl carbonate (DMC) is an organic base and has a wide range of applications in industry. In China, tetramethylammonium hydroxide is mainly used as the main catalyst in the synthesis of silicone products, such as silicone oil, silicone rubber and silicone resin. Although the amount of tetramethylammonium hydroxide is small, it has a great influence on the yield and quality of products. In foreign countries, tetramethylammonium hydroxide is mainly used in polyester polymers, textiles, plastic products, food, leather, wood processing, electroplating, microorganisms and so on.

At present, this product has entered the cutting-edge scientific and technological fields, such as printed circuit boards and the manufacturing of microscopes, can be used as cleaning agent for integrated circuit boards and anisotropic corrosive agent for Si-SiO 2 interface in semiconductor microfabrication technology. With the development of science and technology, the requirement of this kind of chemical reagent is increasing day by day, which requires higher quality and quantity of tetramethylammonium hydroxide.

5. Oil Additives Project

Dimethyl carbonate is also widely used as additive for gasoline and diesel oil after deep processing. Oil additives refer to certain chemicals that can significantly improve the original properties of oil products or give some new qualities to oil products. According to the application, it can be divided into lubricant additives, fuel additives, composite additives and so on. According to the function, it can be divided into detergent, dispersant, anti-oxidant and anti-corrosive agent, viscosity index improver, pour point depressant, anti-explosive agent, metal passivator, flow improver, anti-icing agent and so on.

Dimethyl carbonate can be used as gasoline additive instead of methyl tert-butyl ether (MTBE). The addition of DMC is 10%, which can be converted into 3.3% DMC. At present, the world gasoline consumption exceeds 200 million tons per year. Now our company has done a lot of work on gasoline additives. As long as the national standard is issued, the demand for dimethyl carbonate is nearly 6 million tons.

6. Solvent project

Dimethyl carbonate, as a new low toxic solvent, has been used and industrialized in the domestic market in the paint and adhesives industries. Dimethyl carbonate is widely used in nitro paint, furniture paint, automotive paint, thermoplastic acrylic paint, acrylic polyurethane paint, alkyd polyurethane paint, chlorinated rubber road marking paint and other paints. It can be used in medium and can replace the solvents such as toluene, ethyl acetate, butyl acetate, acetone or butanone currently used. The prepared paint fully meets the technical standards of existing paints. Dimethyl carbonate can also be used as a substitute for ethyl acetate, butyl acetate, acetone or butanone in adhesives industry, and has a promising application prospect. The application advantages of dimethyl carbonate in paint, coatings and adhesives industry are non-toxic, good solubility, high deesterification ability, high surface tension, low viscosity, low dielectric constant, high evaporation temperature, fast evaporation rate and so on. Many domestic paint and adhesives manufacturers have industrialized the substitution of dimethyl carbonate for solvent, such as: Hong Kong Bauhinia lacquer, Guangdong Jiaboli Chemical, Nanhai Bali Chemical, Dongming Resin and other enterprises have been used for a long time, with obvious effect and remarkable economic benefits. Dimethyl carbonate is also being used to replace traditional solvents in many famous paint and adhesives factories in the world. Dimethyl carbonate, as an environmentally friendly green solvent, will have more and more extensive market applications in the context of increasing global attention to environmental protection. At present, the domestic consumption in this industry is 50,000 tons, with an annual growth rate of about 15%.

The company is willing to cooperate sincerely with friends from all walks of life in various forms to seek common development, common prosperity and share fruits.
