Boiling point of Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) is 228 °c. 

The relative density of Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) was 0.9031. 
Melting Point of Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) is -8.3 °c. 

Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) is micro-soluble in cold water, soluble in hot water and ether,
Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) is soluble in ethanol.

PREPARATION METHOD OF HEXANOIC ACID, 2-ETHYL-(2-ETHYLHEXANOIC ACID) (2-EHA):
2-ethylhexanol oxidation method from 2-ethylhexanol in aqueous sodium hydroxide solution by potassium permanganate oxidation to produce sodium isooctate, and then neutralization by sulfuric acid.

2-ethylhexenal oxidation method 2-ethylhexanal was prepared by selective hydrogenation of 2-ethylhexanal, which is an intermediate product of 2-Ethylhexanol produced by propylene carbonyl synthesis, then by liquid phase oxidation to produce 2 ethyl hexanol.

2 ethyl hexanol catalytic dehydrogenation esterification method 2 ethyl hexanol in alkaline conditions, with cadmium oxide, zinc oxide, manganese dioxide as catalyst, 2-ethyl hexanoate (isooctanoate) is formed by dehydrogenation at 180~210 ℃, and isooctanoate is saponified to form corresponding salt and alcohol. 
After the salt is acidified with sulfuric acid, isooctanoic acid is obtained by rectification.

REACTIVITY PROFILE OF HEXANOIC ACID, 2-ETHYL-(2-ETHYLHEXANOIC ACID) (2-EHA):
Hexanoic acid, 2-ethyl-(2-Ethylhexanoic acid) (2-EHA) is a carboxylic acid. 
Carboxylic acids donate hydrogen ions if a base is present to accept them. 
They react in this way with all bases, both organic (for example, the amines) and inorganic. 

Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. 
Neutralization between an acid and a base produces water plus a salt. 
Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. 

Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. 
The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. 

Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. 
Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. 
Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers.

Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. 
The reaction is slower for dry, solid carboxylic acids. 
Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. 

The reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides generates flammable and/or toxic gases and heat. 
Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. 

Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. 
Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. 

These reactions generate heat. 
A wide variety of products is possible. 
Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.
