EPA Chemical Substance Information 2-Butenedioic acid (2Z) -, dioctyl ester (2915-53-9)
Chemical properties: Colorless transparent liquid. The freezing point of -50 ° C, the boiling point of 195-207 ° C (0.67 kPa), the relative density of 0.944 (25 ° C), the refractive index of 1.4535 (25 ° C). Soluble in most organic solvents, insoluble in water.
Uses Used as sodium succinate two acid sodium sulfonate (fast penetrating agent T) intermediates. The product can also be used as an internal plasticizer, with vinyl chloride, vinyl acetate, styrene and acrylic copolymer, the copolymer has excellent impact resistance, cracking resistance, electrical properties and optical properties, Can be used for film, coatings, adhesives, rubber, pigments of fixing agent, oil additives, paper processing agent and so on. The copolymer with vinyl acetate is a rubbery elastomer which can be used as a coating material. A film made of a copolymer with vinyl chloride has a good low-temperature softening agent. But the product in the proportion of copolymer should not be too large, generally not more than 10%. When the content is too large, the heat resistance and the mechanical properties of the copolymer resin decrease.
Use The copolymer can be used as plasticizer, can also be used as adhesives, petroleum additives
