Epoxy group plasticizer are of great use value and are widely used in the market. The epoxy group plasticizer is an ideal intermediate product for chemical modification, which is determined by its functional group, the epoxy group.
Epoxy plasticizers can be used to prepare lubricants and to prepare rubber and other products by polymerization. Epoxidation vegetable oils can be used for the preparation of biodegradable lubricants. They are the most ideal alternatives for petrochemical lubricants and synthetic lipids.
Xuedong Wu et al ring by four ball test determination of epoxidized rapeseed oil and rapeseed oil showed that friction spot diameter is 0.63 and 0.72mm respectively, the epoxidation of rapeseed oil with higher viscosity and friction coefficient at low temperature, preparation of biodegradable materials have the potential.
Brajendra K.Sharma et al. Studied the anhydride of different chain length, modified vegetable oil, and catalyzed epoxidation of soybean oil by acid catalysis, and then through a series of modification methods to improve the stability and oxidation stability at low temperature.
Compared with polymers synthesized by petroleum, biopolymers have great advantages. Their commercial value has attracted more and more attention and become a new research field of epoxy plasticizers. Some scholars have used epoxidized soybean oil with three ethylene glycol, two yuan ammonia to form a polymer, and the composition of this polymer is similar to that of synthetic rubber.
Jingyuan Xu et al. Used to crosslink the reoxygenation soybean oil to form polymer. After studying, we found that the new polymer showed strong solid viscoelasticity similar to that of synthetic rubber, and the rheological properties implied that this biological compound has great potential to replace synthetic rubber and plastics. Maria Augusta de Luc et al. Used four ethoxylsilane to catalyze epoxidized castor oil to form an organic inorganic mixture. The macroscopic and microscopic properties such as adhesion and hardness were analyzed by infrared spectroscopy, and the microstructure was scanned by electron microscope.
The results showed that the hardness and tension increased with the increase of epoxidized oil. The mixture showed good adhesion. The polymer was used to prepare ceramic coatings.
The present situation and Prospect of the production of epoxy plasticizers in China. China is a large agricultural country in the world, with rich oil resources and various varieties, which is very favorable for the development of epoxy plasticizer products in China. At present, the epoxy plant oil plasticizer in China starts late and develops slowly, mainly with epoxy soybean oil as the main source, and the source is single.
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.
Other varieties, such as epoxy linseed oil and epoxy cottonseed oil, have not been well developed, small and dispersed, and the output has not formed a scale, and the level of self-control is low. Therefore, China's plasticizer industry should vigorously develop new varieties of epoxidized vegetable oil, improve control level, form continuous production, realize economic scale output and reduce costs, so as to adapt to the continuous development of plastic products industry.
In addition, in terms of technology, China's epoxy plasticizer production process still by chemical method, but the presence of sulfuric acid catalyst will cause equipment corrosion, but also pollute the environment, the technology is relatively backward, should this technology innovation, promote clean production process, with other good effect and no pollution instead of sulfuric acid catalyst
. Enzymatic synthesis of epoxy plasticizers with lipase as catalyst and mild reaction conditions can avoid equipment corrosion, but the disadvantage is that the cost of enzyme is high and the reaction time is longer. The technology needs further optimization and cost reduction. In addition, the state can give moderate financial subsidies and preferential tax, so that the production of epoxy plasticizer is competitive. Meanwhile, the development plan of epoxy plasticizer is formulated, and the consumption market of epoxy plasticizers is vigorously cultivated.
Epoxy plasticizer has many advantages, such as environmental protection, plasticizing, biodegradation and so on. It has a broad development prospect. The development of the clean production process of plant oil based plasticizers is not only conducive to the full utilization of renewable oil resources, but also has great economic value.
Li Kunlan and others studied the epoxidation of soybean oil under neutral conditions using phosphotungstic Heteropoly salts as reaction controlled phase transfer catalyst, and investigated the influence of reaction conditions on epoxidation. The results show that epoxy soybean oil has more than 6% epoxy value and does not reduce the catalytic activity after 5 cycles. In recent years, many researchers have used metal compounds as catalysts to synthesize epoxy plant oil, which has the advantages of high conversion and less side effects.
Some scholars have found that methyl three oxygen rhenium (MTO) is a good epoxidation catalyst, it is MeRe (O) 2 (R2 O2) and MeRe (O) (R2 O2) 2 (H2O) peroxy intermediates. Annelise et al studied the synthesis of epoxidized soybean oil MTO - CH2Cl2 / H2O2 system, the reaction was optimized and used as the catalyst, and with acid of peracetic acid synthesis of epoxidized soybean oil were compared, the results showed that at room temperature, MTO catalyst system epoxidation effect is much better than the method of peracetic acid.
