English name : 7-Oxabicyclo [4.1.0] surfactant-3 ,4-Xuebing acid, bis (2-ethylhexyl) ester
di (2-Ethylhexyl) -4, 5-epoxycyclohexane-1 ,2-dicarboxylate
4 ,5-Epoxycyclohexane-1 ,2-Xuebing acid, di - (2-ethylhexyl) ester
7 - oxabicyclo (4.1.0) surfactant-3, 4 - Xuebing acid, bis (2-ethylhexyl) ester

nature Description : The colorless to pale yellow oily liquid. Solidification point <-30 ° C and relative density of 1.007 (20/20 ° C), the refractive index of 1.4656 (25 ° C), a flash point of 217 ° C, and viscosity (25 ° C) 118mPa �s. With alcohol; Benzene immiscible organic solvent, do not dissolve in water.

production methods : by maleic anhydride and butadiene 100-110 ° C in the under-Vinyl-response system in tetrahydro phthalic anhydride. The latter with 2 - ethyl hexanol in decompression (1.333 - 2.666kPa) and 120-130 ° C, by sulfuric acid catalyst for esterification. Washed by the reaction products; Distillation of Tetrahydrophthalate 2 ethylhexyl again in sulfuric acid catalyst with hydrogen peroxide in formic acid, benzene solution for epoxidation reaction (55-60 ° C) generated from crude. Crude separation; Washable; And in; Delinking benzene; Bleaching; Filter Press, that is finished. The consumption of raw materials fixed : maleic anhydride 250kg / t; Butadiene 116kg / t; 2 - ethyl hexanol 654kg / t; 30% hydrogen peroxide 570kg / t; Formic acid is 100 kg / t.

purposes : the goods for PVC plasticizers and stabilizers. Plasticized DOP with similar efficiency, better performance than mixed DOP, disposes plasticizer. Low volatile, relocation small, good resistance out. Products can be given to the excellent thermal stability; Resistant Bacteria and durability. Particularly applicable to transparent film such products, but also widely used in artificial leather; Sheet; Sheet; Wire and cable materials; Coatings and various moldings. Plus the goods are products of non-oil solution flu-like phenomenon or exudative. Epoxy Tetrahydrophthalate epoxy ester plasticizer is the best varieties. Epoxy plasticizer molecules contain epoxy structures, including epoxy oil; Epoxidation of fatty acid ester and epoxy tetrahydrocannabinol of phthalate esters, is a type of rapid development of plasticizers, which is more outstanding is a new variety of cyclooxygenase-1 ,2-polybutadiene (C60H90O5); Will as PVC plasticizers, from products have excellent water resistance and the nature of resistance.
