High fatty alcohol benzoate plasticizer
The synthesis and application of high fatty alcohol benzoate plasticizer are introduced in this paper.
Benzoic acid ester, a byproduct of polyester production line, was synthesized from benzoic acid and carbon eight to carbon ten mixed alcohols. Benzoic acid ester plasticizer was synthesized from benzoic acid and benzoic acid. The yield of benzoate was higher than 96%, and the purity of benzoate was higher than 99%. Fatty alcohol benzoic acid ester plasticizer and two diethylene glycol dibenzoate DEDB plasticizer or two formic acid and two octyl phthalate (DOP) plasticizer used in conjunction with the preparation of artificial leather products, soft, like artificial sheepskin performance.
Fatty alcohol benzoic ester plasticizer for preparing benzoic acid methyl ester 544g, 475g Decyl Alcohol Content greater than 99.5%, 3mol 3G N, activated carbon, gas blowing, temperature 150 to 160 DEG C, adding catalyst isopropyl titanate 0.5g, temperature 160 to 180 DEG C, distillate methanol, methanol reflux ratio control. Keep the top temperature determination of methanol content in methanol distillation is greater than 99.9% at 64 2h after the reaction chromatography, gradually reducing the pressure, steamed out excess benzoic acid methyl ester, activated carbon filter, from 200 to 210 DEG C, 2000 ~ 2600Pa fraction was benzoic acid decyl ester 760g (GC content greater than 99.9%), the yield of 96.7%, more than 168 flash point C.
Benzoic acid carbon eight carbon ten mixed ester plasticizer is prepared according to the above method. The appearance is white, the color cobalt cobalt platinum is less than 20, the flash point is greater than 160 degrees, the relative density (20/20 C) is 0.9148 to 0.9150, the refractive index is 1.4908 to 1.4910, and the boiling range is 200~210 2000Pa.
Evaluation of high fatty alcohol benzoic acid plasticizer. The use of polyester production line of by-product benzoic acid and methanol by first esterification to benzoic acid ester, which then exchange income and oleyl senior fatty alcohol benzoate can get high taste, good color, body consumption (by fatty alcohol meter conversion rate greater than 99%) of the PVC plasticizer.
Senior fatty alcohol benzoic acid ester plasticizer with DOP and DEDB can be used to endow the products with soft features, but the aging performance remains to be studied further in the process of using.
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).
The development trend of plasticizers. To improve the plasticizer durability, health, seeking cheap raw materials and the development of functional plasticizer is the trend in this area, to improve the durability of people in recent years more and more attention to a topic, hope that through enhanced durability of plasticizers can make the long-term use in various under the environment, and improve health is caused by the nature of plasticizer, because whether it contained in the production or use of plasticizer in DOP\DOA are toxic carcinogenic function, this is a wake-up call for us in the development of plasticizer in the process, always pay attention to hygiene inspection in this regard, has become particularly important, reduce the plasticizer cost this is the inevitable outcome of the market economy, only to find cheap raw materials, reduce costs, create greater profits, will promote the plasticizer industry itself Exhibition, in the market economy such a fierce competition in the environment to occupy a place.
The development of functional plasticizer reflected from the side with the development of science and technology and society, more and more people on the plasticizer requirements higher, the common function of plasticizer is the special function of plasticizer slowly replaced this is an inevitable demand of science and technology and social progress and results.
Through the grasp of the overall concept of plasticizer, plasticizer and the case of the leading development is introduced, the development trend of plasticizer were also discussed, which makes the readers in his mind as a whole to form a complete plasticizer framework for further study on related fields in this area laid a foundation.
High fatty alcohol, also known as high carbon alcohol, refers to a mixture of more than six carbon atoms. Generally, the alcohol in the range of C6 to C10 is called the plasticizer, and the alcohol above C12 is called detergent and emulsifier. In the early period, the production of oil and plant oil was made. In 60s, the output of oil as the main raw material was increased year by year. In the middle of 80s, the total output was above 5Mt, of which about 65% of the synthetic method was produced. Higher fatty alcohols are mainly made of various ester products, used as polymer plasticizers for rubber and plastics, and also used as detergents, especially ethoxy compounds obtained from addition of epoxides. The latter is not only an excellent detergent, but also a nonionic surfactant, as well as wetting agent, emulsifier, dispersant and so on. In addition, C6 ~ C8 alcohol is also used as an industrial solvent.
Higher fatty alcohol is a straight chain alcohol that contains a large number of carbon atoms. It is nontoxic to human body and is often used as a solvent for cosmetics. Resorcinol is also known as Rex, white needle like crystal, nontoxic, but has bactericidal and antiseptic effects. It is added to cosmetics and dermatological drugs paste and ointment. Hydrogen peroxide is also called hydrogen peroxide, which is easily decomposed into oxygen and water. This oxygen has bactericidal function. They are nontoxic, but it is better not to import them.
