Chemical intermediates, referred to as intermediates for short, are intermediate products that use coal tar or petroleum products as raw materials to manufacture dyes, pesticides, medicines, resins, additives, plasticizers, etc. According to the national conditions and the needs of national economic development, my country divides fine chemicals into pesticides, dyes, coatings, pigments, reagents and high-purity substances, chemicals for information, food and feed additives, adhesives, catalysts and various auxiliaries 11 categories, such as chemicals and daily chemicals, and functional polymers in high-molecular polymers. Our innovations focus on downstream C1-C4 and provide intermediate species of heteroatoms such as N, P, Si, F, etc.
It is used in the production of polyurethane, unsaturated polyester, plasticizer, hardener of gelling agent, thermal stability improver of lubricating oil, etc. It is also used in the production of pesticide pyrethrin, organic peroxide, cyclic musk, polyethylene plastic cross-linking agent and polyether rubber.
Used in the manufacture of polyester resins. Used as a solvent for cellulose acetate, nitrocellulose, shellac varnish, castor oil, a component of fiber lubricants, and a plasticizer, fumigant, synthetic detergent, etc. In addition, dipropylene glycol can be used alone or in combination with diethylene glycol to extract aromatic hydrocarbons from hydrocarbons.
Due to its hydrophilicity, low evaporation, excellent dissolution and coupling, it can be used for stamp primer, ballpoint pen and fountain pen ink removal, as well as rust, paint, and varnish removal. Also used in hard surface cleaners and penetrating oils. Its high boiling point and flash point make it an excellent choice for stove cleaners; it is also the main raw material of UV light curing monomer TPGDA, and also used as a binder for polyurethane elastomers and coatings.
Mainly used as epoxy resin diluent, plastic and fiber modifier, halogenated hydrocarbon stabilizer, food preservative, bactericide, refrigeration system desiccant and aromatic hydrocarbon extractant, etc. Derivatives of glycidyl alcohol are raw materials for industries such as resins, plastics, medicines, pesticides and auxiliaries, and are intermediates for the synthesis of glycerol, glycidyl ethers (amines, etc.), and can be used in surface coatings, chemical synthesis, medicine, pharmaceutical and chemical industry , bactericides and gelling agents for solid fuels.
2-Vinyloxyethanol is a vinyl ether compound. It can achieve the purpose of polymer structure modification and block copolymer synthesis in polymerization. Because of its good adhesion, miscibility and solubility, its homopolymer and copolymer can be used to make adhesives, Lubricants, hair sprays, elastomers, foams, pesticides and surface protection materials. In addition, vinyl ethers containing hydroxyl groups have good performance advantages in the polycarboxylate superplasticizer industry, and are less sensitive to sand and gravel aggregates containing mud and stone powder, and their application effect in commercial concrete is better than traditional methyl alcohol. Polycarboxylate water-reducing agent prepared from allyl allyl alcohol and 3-methyl-3-buten-1-ol.
