Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-ethylhexyl hydrogen adipate 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.

Fire Hazard

2-ethylhexyl hydrogen adipate is probably combustible.

Lubricant base oil and ester compounds

[Problem] To provide: an ester compound having low viscosity, excellent fluidity even at low temperatures, and a high viscosity index; and a lubricating oil base oil that blends said compound therein. [Solution] The present invention provides an ester compound indicated by formula (I). Formula (I) (in formula (I), R1 indicates a C1–35 hydrocarbon group and at least one hydrogen in the hydrocarbon group can be independently substituted for a group indicated by formula (II)). Formula (II) (in formula (II), R2 indicates a C1–30 linear alkyl or a C3–30 branched alkyl.)

Synergism of microwaves and immobilized enzyme catalysis in synthesis of adipic acid esters in nonaqueous media

Low-energy microwave irradiation leads to enhancement by a factor of up to 2.63 in comparison with conventional heating in immobilized lipase-catalyzed esterification of adipic acid with various alcohols and this effect is due to the greater frequency of collision, without any change in activation energy of the two modes of heating.
