Environment-friendly plasticizer
At present in the world for environmental friendly plasticizer development lags behind the production and living needs, with the progress of science and technology, some traditional materials may be eliminated, new environmental protection research and development advantages of harmless, cheap, good effect of additive plasticizer as substitute materials, is a key part of development of the plastics industry the. Enterprises should increase the strength of research and development, and develop new varieties of environment-friendly plasticizers.
Citric acid ester products as a new type of green plastic plasticizer, non-toxic and tasteless, can replace the traditional adjacent benzene two formic acid ester plasticizer, widely used in food and pharmaceutical packaging equipment, cosmetics, daily necessities, toys, military supplies and other fields, but also an 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 butyl ester three (ATBC), citric acid (ATOC), three - that is the most safe plasticizer, can be used for a variety of PVC products, but it when in use is easy to precipitate 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.
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.
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.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.
Safety data for export goods of two octyl terephthalate (plasticizer DOTP)
CAS No.:6422-86-2
State of the goods: export by general goods.
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.
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 butyl ester of acetyl citrate is a chemical substance of CAS 77-90-7. Colorless and odorless oily liquid, boiling point 343 degrees (0.101MPa), flash point (open cup) 204 degrees, freezing point -80 C, evaporation speed 0.000009g/cm2? H (105 C), hydrolysis speed 0.1% (100 C, 6 hours), dissolved in most organic solvents, insoluble in water. Compatible with PVC, polystyrene, vinyl chloride vinyl acetate copolymer, cellulose nitrate, stem cellulose, polyvinyl butyral resin B. It is partly compatible with cellulose acetate and cellulose acetate butyrate. The cold resistance and light resistance and tributyl citrate is similar, but better water resistance. Nontoxic, LD50=4000mg/kg.
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.
The acetyl citrate three octyl ester is a colorless and transparent oil like liquid. The boiling point is 225 C (133.3Pa), and the flash point (cup) is 224 C. The cold resistance is good, and the volatility is very small. As a plasticizer, under the same formula and conditions, the volatilization loss of this product is only 1/4 of two octyl ester of phthalic acid two formate.
Three octyl citric acid was synthesized from citric acid, n-octanol and acetic anhydride with p-toluene sulfonic acid as the catalyst.
Acetyl citrate three octyl ester can be used as plasticizer of PVC and vinyl chloride copolymer, and can also be used as stabilizer for polyvinylidene chloride (pvvvd). This product is non-toxic plasticizer. It can be used in non-toxic PVC granulation, children's soft toys, medical products, food packaging products, paint ink industry and so on.
