7-Oxabicyclo[4.1.0]heptane-3,4-dicarboxylic acid, bis(2-ethylhexyl) ester;EPS;Flexol 107-7;di(2-Ethylhexyl)-4,5-epoxytetrahydrophthalate;di(2-Ethylhexyl)-4,5-epoxycyclohexane-1,2-dicarboxylate
Molecular formula : C24H42O5
MW : 410.60
CAS No. :10138-36-0

nature : a 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.

Preparation : 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 product, the distillation system 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 separated, washed, and, from benzene, bleaching, pressure filtration, namely finished. The consumption of raw materials fixed : maleic anhydride 250kg / t, 116kg butadiene / 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, resistance to bacteria and durability. Particularly applicable to transparent film such products, but also widely used in artificial leather, sheets, sheets, wire and cable materials, paints 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, epoxy ester of fatty acids and epoxidation Tetrahydrophthalate ester, 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.
