Solvent

Dibutyl phthalate (DBP) is a kind of phthalate esters (PAEs). As a plasticizer, DBP is widely used in plastic processing industry. Monobutyl phthalate (MBP) is a degradation product and synthetic intermediate of DBP.

Dibenzofuran is an excellent high boiling point organic solvent, which can dissolve a variety of high molecular compounds. It can also be used as raw materials for medicine, disinfectants, preservatives, fuels, synthetic resins and high-temperature lubricants. For example, some derivatives of dibenzofuran have anti-inflammatory, analgesic, muscle relaxation and vasodilation activities. In addition, dibenzofuran can also form eutectic mixture with biphenyl as heat transfer solvent.

Diethyl adipate is a fatty acid ester.

Used as chemical reagent, solvent, emulsifier, rubber accelerator, corrosion inhibitor, etc. It is used as gas chromatography stationary liquid, and GB 2760-96 stipulates that it is allowed to be used as processing aid for food industry. It is used to remove acid gas from natural gas and petroleum gas and manufacture non-ionic detergent, emulsifier, etc. Monoethanolamine is mainly used as plasticizer, vulcanizing agent, accelerator and foaming agent of synthetic resin and rubber, as well as intermediate of pesticide, medicine and dye. It is also the raw material of synthetic detergent and emulsifier for cosmetics. Textile industry as printing and dyeing whitening agent, antistatic agent, mothproof agent and detergent. It can also be used as carbon dioxide absorbent, ink additive and petroleum additive. Monoethanolamine is widely used as a purification solution for extracting acidic components from various gases (such as natural gas). Piperazine hexahydrate can be prepared by cyclization and neutralization of monoethanolamine hydrochloride. Monoethanolamine hydrochloride can be prepared by chlorination of sulfoxide chloride and substitution of sodium thiosulfate β- Aminoethyl thiosulfate. This is a dye intermediate for the production of polycondensation turquoise blue 13g. Thiothiazoline, an intermediate used in rubber and pharmaceutical industry, can be prepared by the reaction of monoethanolamine with carbon disulfide. Monoethanolamine is an important corrosion inhibitor, which plays a role in boiler water treatment, coolant of automobile engine, drilling and cutting oil and other lubricating oils. However, monoethanolamine should not be combined with nitrite corrosion inhibitors to prevent the formation of nitrosamine carcinogens. It is mainly used as absorbent for acid gases (such as hydrogen sulfide, carbon dioxide, etc.) in petroleum gas, natural gas and other gases. It can also be used as plasticizer, preservative, accelerator, crosslinking agent, cosmetic emulsifier, foaming agent, fabric mothproof agent, ink additive, printing and dyeing whitening agent, rubber vulcanizing agent, antistatic agent, etc. It is also the raw material for the synthesis of pharmaceuticals, pesticides, dye intermediates and surfactants. Used as liquid chromatography solvent, eluent and additive. It is used as tail sealing agent in the preparation of liquid chromatography stationary phase. It is mainly used as detergent and solvent detergent. It is also used in the preparation of textile printing and dyeing whitening agent and emulsifier. It is also used as carbon dioxide absorber, ink additives, petroleum additives, pesticides and pharmaceutical intermediates. It can also be used as a solvent for absorbing acid gas in natural gas and as emulsifier matrix and penetrant in cosmetics. Monoethanolamine can be used as a gas purifier to absorb hydrogen sulfide, carbon dioxide and other acid gases in natural gas, refinery gas and syngas. Monoethanolamine is an intermediate for the preparation of emulsifier and is used as antistatic agent, mothproof agent and detergent in textile processing.

Tetraethylene glycol dimethyl ether can be used as an excellent solvent for alkaline gold hydrides. Used in various chemical reaction processes such as alkylation, condensation, and reduction. Due to its Lewis alkalinity, this compound can selectively absorb acidic gases for purification of gases such as synthetic gas, natural gas, and acetylene.
