Usage

Chemical Properties

Di(2-ethylhexyl) isophthalate has a water solubility of less than 0.1 g/100mL at 16℃. It is a colorless liquid.

General Description

Clear light yellow viscous liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

BIS(2-ETHYLHEXYL)ISOPHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition BIS(2-ETHYLHEXYL)ISOPHTHALATE emits acrid smoke and irritating fumes.

Fire Hazard

BIS(2-ETHYLHEXYL)ISOPHTHALATE is probably combustible.

PLASTICIZER COMPOSITION, RESIN COMPOSITION AND METHOD FOR PREPARING THEREOF

The present invention relates to a plasticizer composition, a resin composition and a method for preparing thereof. The present invention can provide a plasticizer composition, which can improve properties required to the plasticizer composition contained in a vinyl chloride-based resin composition, such as plasticizing efficiency, volatile loss, and migration resistance, to a level equal to or better than the existing plasticizer composition, and a resin composition comprising thereof.

Nano-SO42-/TiO2catalyzed eco-friendly esterification of dicarboxylic acids

Nano-SO42-/TiO2 was prepared by wet impregnation method. The structure and properties of the prepared nano-SO42-/TiO2catalyst was characterized by XRD, SEM, TEM and BET analysis. The catalytic activities of the catalysts were tested by the esterification of sebacic acid with 2-ethyl hexanol and a series of other dicarboxylic acid. The influence factors on the reaction, such as the catalyst calcination temperature, reaction temperature/time and the molar ratio of acid to alcohol were extensively explored. Nano-SO42-/TiO2prepared exhibited much higher catalytic activity in esterification reactions. By applying the optimized reaction condition, i.e. 160 C, 2 h, 5 wt % nano-SO42-/TiO2with a 1:3 molar ratio of sebacic acid to 2-ethyl hexanol, higher than 99 % isolated of the desired ester could be obtained.
