Epoxy linseed oil plasticizer
Study on the synthesis method of epoxy linseed oil plasticizer. Vegetable oil is an important new type of plasticizer epoxidized linseed oil plasticizers on the plasticization of polyvinyl chloride not only, and can be quickly absorbed by the hydrogen chloride from degradation of heat and light, reduce the formation of hydroxy chloro allyl conjugated double bonds not stable, continuous decomposition of poly vinyl chloride plastics block therefore, it plays a role of stabilizer.
At the same time, epoxy linseed oil plasticizer can be combined with polyester plasticizer, which has obvious synergistic effect on reducing migration of polyester, and can synergistic effect with organic metal salt stabilizer, and reduce the amount of organic metal salt.
Synthesis of sesame oil. 250g flaxseed oil, 60g formic acid and 100mL petroleum ether were placed in the 1L reaction bottle equipped with electric stirring, thermometer and dropping funnel, and the reaction bottle was placed in constant temperature water bath. Stirring, heating to the temperature of 60 DEG C, slowly dripping solution containing phosphoric acid hydrogen peroxide (hydrogen peroxide 330g phosphoric acid 1mL), the temperature dropping when the remained at 65 to 68 DEG C after drops in temperature control of 68 ~ 70 DEG C, stirring 3 ~ 4H reaction is completed.
The reaction mixture was transferred to the separation funnel. The water was separated from the water layer. The oil layer was washed for 1~2 times with 5% sodium bicarbonate solution 100. The distilled water was washed to neutral, and the evaporated solvent was reduced to 260 to 275g. The epoxy value of 7.8% ~ 8.1% <9, iodine value, flash point of 315 DEG C, the density of 1.025 ~ 1.030g/ml, <0.7 acid, the product fully meets the epoxidized linseed oil plasticizer standard.
The effect of different organic acids on the reaction of epoxidation. The cyclic oxidation of acetic acid and formic acid as organic acids shows that formic acid is obviously superior to glacial acetic acid as an organic acid.
The epoxidation with acetic acid, which use a large amount of catalyst, reaction of 7 ~ 8h, epoxy value of up to 6.81%, the lowest value was more than 25. The epoxidation reaction with formic acid, in the presence of a very small amount of catalyst, reacted from 3 to 4h, and the epoxy value reached the highest value.
The effect of different catalysts on the reaction of epoxidation. Using 732 resin and a small amount of phosphoric acid as catalyst respectively, it is found that the effect of phosphoric acid as catalyst is much better than that of resin, and the price is cheap and the post-treatment is simple.
The effect of the amount of hydrogen peroxide and the reaction time on the epoxidation reaction. The oil 50g, 0.3ml phosphate, Hydrogen Peroxide 50 ~ 70ml, different reaction time determination of epoxy value changes, results show that under certain conditions, hydrogen peroxide is 60 ~ 70ml had no significant difference under 55mL has obvious difference; the reaction time of 3 ~ 5h for epoxy value is the highest, but with the prolonging of reaction time, the epoxy value is affected by decreased.
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.
The effect of the amount of catalyst on the reaction of epoxidation. Using 50g linseed oil, 60mLH2O2, 15mL acid, 30ml petroleum ether, 0.1 ~ 0.3mlH3PO4 as catalyst for experiment, determination of epoxy value, the results showed that H3PO4 dosage of 0.1 ~ 0.3ml epoxy value were high, almost no obvious difference, but considering the factors of iodine and other aspects, with 0.12 ~ 0.20ml is appropriate.
Synthesis and application of high fatty alcohol benzoate plasticizer. 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%.
With 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. PVC plastics are repolymerized from acetylene gas and hydrogen chloride to the synthesis of vinyl chloride.
In the early 1950s, it was produced by acetylene carbide process. In the late 50s, it turned to ethylene oxidation with enough raw materials and low cost. At present, more than 80% of the world's PVC resin is produced by this method. But after 2003, the cost of acetylene carbide method was 10% lower than that of ethylene oxidation because of the skyrocketing oil price, so the synthetic process of PVC turned to acetylene carbide process.
PVC plastic is made from vinyl chloride liquid monomer (VCM) by suspension polymerization, emulsion and bulk or solution process into the suspension polymerization process mature production technology, simple operation, low production cost, product variety, a wide range of applications, has been the main method of production of PVC resin, accounted for about 90% of the proportion in the world in the production of PVC (PVC in the world total production of homopolymer also accounted for the proportion of about 90%). The second is the emulsion method, which is used to produce PVC paste resin. The polymerization reaction is initiated by free radicals. The reaction temperature is generally 40 to 70OC. The reaction temperature and initiator concentration have great influence on the polymerization rate and the molecular weight distribution of PVC resin.
