2017-12-17 17:32:13
Citrate plasticizer, as a new green plastic plasticizer, is nontoxic and tasteless, and can replace the traditional plasticizer of phthalic acid ester. Citric ester plasticizers are widely used in food and medical instrument packaging, cosmetics, daily necessities, toys, military products and other fields. Meanwhile, citric ester plasticizers are also important chemical intermediates.
Acetyl citric ester has better performance and wider application. It is not only a non-toxic, tasteless green plastic plasticizer, but also an improved agent for polyvinylidene chloride stabilizer and film to metal bonding. Its adhesive has strong adhesion when it is immersed in water for a long time.
The United States, the European Union and other developed countries have issued regulations, allowing citric ester products as one of the plastic additives that are closely related to children's toys, hygiene products, medical devices, artificial leather and other health related products. Our country began to study and develop citrate in the middle of the 90s of last century.
Our country mass production of citric acid esters, such as citric acid butyl ester three (TBC), three citric acid ester (TOC), acetyl citric acid three ~ d (ATBC), citric acid (ATOC), three ~ Essien is believed to be the most secure plasticizer, can be used for a variety of PVC products. But it is easy to precipitate in the use of DOP. At present, our country has developed the environment-friendly plasticizer TBC, which has been applied in the pharmaceutical products. In the future, it can be gradually popularized in other production industries.
1, 2 one or two two isopropyl cyclohexane carboxylic acid is little mobility, is a colorless transparent liquid with slight odor, soluble in many solvents, and many PVC commonly used plasticizer monomer compatibility good, almost insoluble in water, can be used for the tube and the transfusion bag and many other soft medical products that can provide the ideal solution to meet the safety requirements for toys factory, and reach the new EU regulations.
In chemistry, there are four butanol isomers: n-butanol, isobutanol, butanol, tert butanol, corresponding three citric acid butyl has four isomers of tributyl citrate, citric acid, isobutyl three citric acid three and citric acid tert butyl butyl ester. The industry, as the plasticizer is the best performance of tributyl citrate, citric acid isobutyl ester three, citric acid three sec butyl rare.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
TBC molecular formula C18H32O7, molecular weight of 360? 44 g/mol, colorless or light yellow liquid, with acetone, acetic acid, CCl4, mineral oil, castor oil, alcohol and mixed solvent; insoluble in water, non-toxic and tasteless, volatile small, light heat resistant, good compatibility with resin, vinyl acetate, cellulose acetyl cellulose butyrate, ethyl cellulose, benzyl cellulose, as the plasticizing efficiency good plasticizer; also has anti bacteria and bacterial growth, no irritation, flame retardant and biodegradability; LDG50 oral >7 mL/ rats (kg weight), cat >3? 5 mL/ (kg weight), with feed 10%TBC rats after 8 weeks after no organ abnormality. TBC is insoluble in the animal body and is discharged from the body. It has no influence on people and is safe. The quality of domestic products and high-quality TBC sub level products, indicators are: appearance colorless transparent liquid, nearly colorless transparent liquid; color (iodine colorimetry) = 50; acidity (as citric acid mg KOH/g) less than or equal to 0? 015; water is less than or equal to 0? 3; 7%; the content is more than 99? D2041? 037~1? 047.
Citric acid three octyl ester is nontoxic plasticizer and can be used in non-toxic PVC granulation, children's soft toys, medical products, food packaging products, paint ink industry and so on.
Three citric acid ester is a kind of widely used non-toxic plasticizer, the cold resistance, light resistance and excellent water resistance, can be used for polyethylene, PVC and all kinds of cellulose resin, plasticizer, has the advantages of good compatibility, high plasticizing efficiency, non-toxic, low volatility, excellent light resistance, resistance to rotation water resistance; can also be used for food packaging and health care products and children's toys and other fields, adjacent benzene two formic acid ester can replace carcinogenic plasticizer; in addition, can also be used as a protein solution of defoaming agent.
Citric acid three octyl ester is usually obtained by esterification of citric acid and industrial octanol (2- ethyl hexanol) under the action of catalyst and water holding agent, and then refined to obtain industrial products. In the classical process, sulfuric acid is used as a catalyst under vacuum conditions, and the new process is mostly non sulphuric acid catalyst under normal pressure. Non acid catalyst used is also useful organic tin titanate. The water carrying agent is often used in industrial octanol itself. The reaction temperature is generally about 220 degrees centigrade.
Three butyl ester of acetyl citrate is a nontoxic plasticizer. It can be used as plasticizer for PVC, cellulose resin and synthetic rubber. It is used for non-toxic PVC granulation, food packaging container, children's toy products, medical products, film, sheet, cellulose coating and other products. It can also be used as a stabilizer for polyvinylidene two chloroethylene.
