A new nontoxic plastic plasticizer
The plasticizer commonly used in industry is o-phthalic acid two ester. Because it can induce carcinogenesis, it has been strictly controlled in foreign countries. China has also formulated relevant regulations, and will gradually eliminate its use in food packaging materials, medical devices and toys.
Three butyl citrate (TBC) is a new nontoxic plastic plasticizer. It has attracted wide attention due to its characteristics of good solubility, high plasticizing efficiency, innocuity, no volatilization and strong weatherability. It has become the first choice to replace o-phthalate two formic acid green products. With the enhancement of environmental awareness and the improvement of environmental regulations, the development and production of a new nontoxic plastic plasticizer, n-butyl citrate, has excellent prospects for development.
New non-toxic plasticizer citric acid butyl ester three is usually made of citric acid and butanol in the presence of catalyst and the traditional catalyst is concentrated sulfuric acid, although its low price, high catalytic activity, but there are serious equipment corrosion and postprocessing of complex process, reaction difference, serious environmental pollution and other defects, so study on seeking alternative catalysts of concentrated sulfuric acid is very active, have found many good catalytic effect of catalyst:
Sodium bisulfate was used as a catalyst for the synthesis of three butyl citrate. Sodium bisulfate is strong ionic compounds, the study found that it is soluble in water, aqueous solution is strongly acidic, but insoluble in organic acid and alcohol reaction system, can be used as catalyst for the esterification reaction, it is found that the catalyst has the advantages of high catalytic activity, good stability, high yield, easy separation, synthesis methods simple, no corrosion, no pollution etc..
Solid superacid catalyzed synthesis. Strong acid is an acid with stronger acid strength than 100% sulfuric acid. The research shows that the catalyst used as esterification reaction has good selectivity, fast reaction speed, high yield, easy separation, easy operation, stable catalyst, repeated use, no corrosion and no pollution. It is a promising catalyst.
Catalytic synthesis of p-toluene sulfonic acid. Toluene sulfonic acid is a strong acid, use it instead of concentrated sulfuric acid as esterification catalyst and corrosion of equipment pollution than sulfuric acid much smaller, high activity, good selectivity, low cost, less dosage, the color of the product is good, is a catalyst for industrial production.
Heteropoly acid catalyzes the synthesis of three butyl citrate. Heteropoly acid is multiple proton acid, the more acidic, more conducive to the formation of salt, provide more favorable conditions for other nucleophiles attack, so as to accelerate the esterification rate. It has no volatilization, good thermal stability, low pollution and can reduce the corrosion of equipment, is an ideal catalyst for esterification reaction.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.

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.
Three citric acid ester (TBC) can be attributed to the products with good cold resistance, water resistance and mildew resistance. After being plasticized, the resin exhibits good transparency and low temperature curling performance, and has low volatile and low extraction properties in different media, good thermal stability and no color change when exposed to heat. The lubricating oil prepared by this product has good lubricity.
Three butyl citrate (TBC) is a good environment-friendly plasticizer and lubricant. At normal temperature, it is nontoxic, fruit flavour, colorless and transparent oil like liquid. The boiling point is 170 C (133.3Pa), and the flash point (cup) is 185 C. Soluble in most organic solvents. It has the advantages of low volatility, good compatibility with resin and high plasticizing efficiency. It is allowed to be used in food packaging and medical products, as well as soft toys, pharmaceuticals, medical products, flavors and fragrances, cosmetics manufacturing and other industries in Europe and America.
Industrial grade three butyl citrate is suitable for plasticizers of polyvinyl chloride, copolymer of chlorinene and cellulose resin. Good compatibility, high plasticizing efficiency, cold resistance, light resistance and water resistance, small volatility, micro toxicity, and anti mildew resistance. It can also be used as plastic plasticizer for food packaging and medical and health products and children's toys. Colorless and transparent oil like liquid, tasteless. The boiling point is 170 C (133.3Pa), and the flash point is high (open cup) 185 C. Soluble in most organic solvents.
Three butyl citrate is less volatile, and has good compatibility with resin and high plasticizing effect. Can make products with good cold resistance, water resistance and mildew resistance. Nontoxic, LD50=2900mg/kg. Toxicity: This product is nontoxic. The rats were not toxic at the dose of 10-30ml/kg at the dose of acute LD50>30ml/kg. Packing: drum, 200KGS/ drum storage: store in a cool, dry and ventilated place, according to the general chemical transportation.
Citric acid and n-butanol act on the presence of catalyst and water holding agent to form three butyl citrate. The products are obtained through dealcoholization, neutralization, water washing, stripping, decolorizing and pressure filtration. The commonly used catalysts are inorganic or organic acids, and the water carrying agent is n-butanol itself.
Three citric acid butyl usually tributyl citrate, chemical name 3- -3- three hydroxy carboxyl glutaric acid butyl ester compounds, is a colorless transparent liquid, high boiling point, slightly soluble in water, soluble in most organic solvents. In industry, it is made from citric acid and n-butanol, which can be directly applied to plasticizers, and can also be further processed into excellent performance plasticizer acetyl citric acid, three butyl ester. This product is low toxic, can be seen as a non-toxic plasticizer, commonly known as the environment-friendly plasticizer, can replace the application scope of the restricted phthalic acid ester plasticizer.
