High quality Triethyl Phosphate

Triethyl Phosphate is an ethylating agent for nitrogen heterocyclic compounds. TEP is used as a solvent for synthesis of organicc chemicals especially acetic anhydride. It is used as a raw material to manufacture Tetraethyl Pyrophosphate(TEPP). TEP is used as a flame retarding plasticizer or additive for cellulose, polyester and polyurethane. It is used as an intermediate in manufacturing of phosphonate esters and vinyl phosphates.

Synthesis of triphenyl phosphite

This product is an important chemical raw materials, is lower than room temperature, colorless to pale yellow crystals, above room temperature is a colorless or light yellow transparent liquid, melting point 22 ~ 24 ℃, under atmospheric boiling point 360 ℃, relative density 1. 184 (20 ℃), the refractive index of 1.5900 (20 ℃), insoluble in water, soluble in ethanol, benzene and acetone and other organic solvents.

Triphenyl phosphite is mainly used in polymer antioxidants and stabilizers, and many phenolic antioxidants have good synergy, mainly for polyolefin, polyester, ABS resin, epoxy resin, synthetic rubber and other products, so that products can maintain transparency and suppresses color change; also used as a plasticizer fiber film having excellent transparency and water resistance; for engineering plastics, phenolic resins, and halogen flame retardant preparation and use, can play a role in flame oxidation, and both light stability; also made an important intermediate take trialkyl phosphite esters.

Triphenyl phosphite synthesis of phenol and phosphorus trichloride as raw material batch esterification process has been triphenyl phosphite, study material ratio, reaction temperature and time on product quality, to determine the optimum process parameters.

experimental method
Equipped with a stirrer, a thermometer, air cooling, drying tube of 1000mL first four-necked flask was replaced with nitrogen, then add phenol 480g, heating temperature, turn the material melted when stirred, a solution of phosphorous trichloride when the temperature reached 30 ℃ 240g, the control of dropping, the dropping time of about 2h; After the addition nitrogen gas flow rate of 0.6m3 / h, maintaining the 1.5 ~ 2h, then heated to 130 ~ 140 ℃, reaction under nitrogen for 5 ~ 6h, water ring vacuum pump to remove unreacted phenol and residual HCl gas; vacuum distillation, collecting 207 ~ 212 ℃ / 0.13 kPa of distillate products.

I plant mainly produces antioxidant stabilizer triphenyl phosphite, mainly export-oriented, 80 tons per month.

Thermal stabilizer trimethyl phosphate TMP-modified polyester technology to improve product performance polyester

 

Polyester film (BOPET) are used as packaging materials throughout, the market increasingly demands progress against it. Thermal stabilizer trimethyl phosphate TMP-modified polyester technology to improve product performance polyester, by copolymerization, modification, surface modification coating essentials, modified polyester raw material, can improve the BOPET film Performance in isolated, high temperature, UV, heat-sealable and so on. Polyester (PET) refers to the ester group-containing thermoplastic polyester short. As a member of a saturated thermoplastic polyester, polyethylene terephthalate plastic packaging materials used throughout most kind. It can be used for a variety of bottle molding containers, sheets and films.

Among them polyester film (BOPET) the largest application market is flexible composite materials, 50% of the total amount. People living water is usually beneficial improvements to the packaging material requirements are also getting higher and higher, for example, require a high isolation, high heat resistance, high transmittance, high light, low haze, anti-ultraviolet radiation, fire-retardant , heat-sealable, meet food hygiene requirements and so on. Obviously, ordinary polyester film can not meet these requirements, we shall be in accordance with the requirements of a difference, from the perspective of the difference must be modified PET.

Our production and export of trimethyl phosphate, exported to Japan, South Korea, India, the United States and other countries. 80 percent of exports.

Polyester thermal stabilizer trimethyl phosphate normally used (TMP) or triphenyl phosphate (TPP), their low phosphorus content, a large addition amount, an amount causes excessive drop melting point PET, transparency and impact ʱ?? France introduced a new thermal stabilizer triethyl phosphate (TEPA), is reported to make PET low haze, transparency and progress. Development of new, efficient, non-toxic, non-polluting heavy metal catalyst is a polyester production skills progress and an important part. Currently, the vast majority of the catalyst used in the polyester production apparatus antimony catalysts are, for example, antimony trioxide, antimony acetate, antimony ethylene glycol and the like. The fear is that antimony belong to heavy metals, is not conducive to environmental protection, and even may be hazardous to human health. Therefore, to develop free of heavy metals, no environmental pollution, polyester catalyst needs very healthy, especially as PET food packaging materials, the more a sense of urgency.
