Polyvinyl chloride / vinyl chloride copolymer plasticizer
Two octyl phthalate is one of the most widely used plasticizers of PVC / vinyl chloride copolymer. Polyvinyl chloride / vinyl chloride copolymer plasticizer, two octyl two acid octyl ester, has high plasticizing efficiency, low volatility, UV resistance, water resistance, small mobility, and good cold resistance, softness and electrical properties. It is an ideal plasticizer.
Polyvinyl chloride / vinyl chloride copolymer plasticizer, two octyl benzoic acid two octyl ester, is widely used in PVC, vinyl chloride copolymer, cellulose resin processing, manufacturing thin film, artificial leather, electric wire and cable wrapping, sheet, plate, molding, plasticizing paste and so on.
For nitrocellulose lacquer, it can improve the elasticity and tensile strength of the film. The adjacent benzene two formic acid two ester can be used as synthetic rubber such as nitrile rubber Ruanhua agent, can improve the resilience of products, reduce the compression permanent deformation, and no effect on the curing compound.
The toxicity of two octyl ester of phthalic acid two formate was low, and the LD50>30g/kg weight of rats and rabbits passed through the mouth. The food and Drug Administration of the United States permits the two octyl of phthalate two formate to be used in glassy paper, coatings, adhesives and rubber products for food packaging.
Transport: shipped in a tank car, two octyl phthalate should be stored in ventilation, drying, and away from the fire source.
Phthalic acid two formic acid two octyl abbreviation: DOP. A colorless or yellowish oily transparent liquid. The chromaticity (APHA) < 30. Acidity (with phthalic acid two formic acid) < 0.01%. ester content 99%~100%. The relative density is 0.980~0.986g/cm3 (25 C), the viscosity is 80mPa.s (20 degrees C), and 58mPa.s (25). The freezing point is -53 C, and the boiling point is 386 C (0.1MPa). The flash point (cup opening method) is 216~218 C, and the refractive index is 1.4830~1.4859 (20 C). The solubility of water in water is less than 0.01% (25 C), and the solubility of water in two octyl phthalate is 0.2% (25 degrees C).
Soluble in most organic solvents and hydrocarbons, slightly soluble in ethylene glycol, glycerol and some amines, and most industrial resin such as polyvinyl chloride, ethylene vinyl acetate copolymer, polystyrene, polymethyl methacrylate, fiber weft, nitrate ethyl cellulose, cellulose acetate resin and rubber has good compatibility, and cellulose acetate, polyvinyl butyral polyvinyl acetate, soluble part.
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.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
Phthalic acid two formic acid two cheeses, also known as phthalic two formic acid two (2 - ethyl) cheese (DOP), molecular formula: CeHd (COOC:Hl?) Z. Molecular weight: 390.56, the appearance is colorless or yellowish oily liquid, the boiling point of 386 DEG C: (760mmHg), freezing point: 55 C, 192 C, flash point: refractive index: 1.483 L 486, ignition: 241 C, teach: 804mPa? S (20 DEG C), flow: 41 C solubility: 25 DEG C, in dissolved 100g 0.01g, miscible with ethanol, ether and other organic solvents.
DOP can react with water in the catalysis of acid or base to produce o-phthalic acid two or its sodium salt and octanol. At high temperature, DOP can be decomposed into o-benzoic acid, two anhydride and olefins. DOP has other chemical properties of general cheese. DOP has a potential toxicological effect on people.
The main raw materials used for the production of two - isocysin, phthalic acid, two formic acid, are phthalic and 2 - ethyl hexanol. The phthalic anhydride can be oxidized by the oxidation of vegetables and dimethylbenzene. In 1926, the phthalic anhydride was obtained by the gas solid phase catalytic oxidation of the case. The catalyst used is more than L VzOs K2SOd Si02, the contact time is 4 - 53, the reaction temperature is 360, 370 370, the theoretical yield of phthalic anhydride is 81.3% 1 84.8%, and the quality yield is 94% 1 98%.
The resource of coke is limited and the price of oil case is more expensive, so the process of o-phthalic anhydride to oxidize o-xylene to phthalic anhydride is developed. The phthalic anhydride produced by this process has accounted for 80% of the world's total. The fixed bed oxidizer, VzOs - TiOz as the main catalyst, was used as the main catalyst for the catalytic oxidation of gas phase. The yield of the catalyst was up to 82.8%, the yield of the catalyst was up to 109%.
The alcohols used for phthalic acid two formic acid cheese are long carbon chain aliphatic alcohols, which are prepared mainly by carbon based synthesis, alkyl aluminum and ester high pressure hydrogenation.
Carbon based synthesis can make the rich petrochemical products such as propylene and isobutylene change into many intermediate and advanced monoalcohols. For example, using propylene as raw material, n-butyl aldehyde and isobutyl aldehyde can be prepared by carbon based synthesis, and n-butyl alcohol and isobutanol can be further synthesized.
2 - ethylhexyl alcohol is obtained by condensation reaction, dehydration and hydrogenation of n-butyl aldehyde, which is also known as the "octanol" in industry.
The reaction of the esterification of phthalic anhydride and octanol to DOP. The first step is the irreversible reaction. It will react quickly at room temperature to form a single cheese. The method is different from the production process. Sulfuric acid can oxidize the alcohol to aldehyde, dehydrate the alcohol into olefin or ether, and causes the color to be deepened.
