2-Ethylhexyl nitrate

Lubricants, Fuels, and Petroleum. The adipate and azelate diesters of through alcohols, as weU as those of tridecyl alcohol, are used as synthetic lubricants, hydrauHc fluids, and brake fluids. Phosphate esters are utilized as industrial and aviation functional fluids and to a smaH extent as additives in other lubricants. A number of alcohols, particularly the Cg materials, are employed to produce zinc dialkyldithiophosphates as lubricant antiwear additives. A smaH amount is used to make viscosity index improvers for lubricating oils. 2-Ethylhexyl nitrate [24247-96-7] serves as a cetane improver for diesel fuels and hexanol is used as an additive to fuel oil or other fuels (57). Various enhanced oil recovery processes utilize formulations containing hexanol or heptanol to displace oil from underground reservoirs (58) the alcohols and derivatives are also used as defoamers in oil production.

The most common compound used to improve the cetane number of distillate fuel is 2-ethylhexyl nitrate, an isooctyl nitrate. Dibutyl peroxide, certain glycols and other nitroparaffins are also effective at improving the cetane number of diesel fuel, but their acceptance is not as widespread as isooctyl nitrate. 

Important physical properties of 2-ethylhexyl nitrate are provided in TABLE 6-4.

Ethylhexyl nitrate (EHN) is the most widely used cetane number improver. It is also sometimes called, octyl nitrate . EHN is thermally unstable and decomposes rapidly at the high temperatures in the combustion chamber. The products of decomposition help initiate fuel combustion and, thus, shorten the ignition delay period as compared with that of the fuel without the additive.

A variant solvent formulation was developed in China (INET), involving (2-ethylhexyl)-phosphonic acid 2-ethylhexyl ester (HEHEHP) as the extractant (saponified to 40% with concentrated ammonia), dissolved at 1.5 M in kerosene, to recover, in 43 stages, 99% of Am(III) and remove 90% of Ln(III) from a 0.2 M nitrate feed (pH 1) (237). 

Separation by solvent extraction Uranium can be extracted from aqueous solutions using extraction agents into the solvent phase, from which it can be stripped. The extraction agents used are phosphorus compounds such as di-(2-ethylhexyl)-phosphate, tri-n-butyl-phosphate and tri-n-octylphosphine oxide as well as primary, secondary and tertiary amines in salt form or as quaternary ammonium salts. The extraction agents are diluted with inert hydrocarbons, preferably kerosene, to concentrations of 4 to 10% by volume. The solubility of the amine salts, particularly the hydrogen sulfates, chlorides and nitrates is increased by adding long chain alcohols (e.g. isodecanol). 

The separation of yttrium from holmium and erbium by chromatography and elution at different acidities was investigated during a study of the distribution coefficients of the elements in chloride and nitrate systems of bis(2-ethylhexyl) phosphoric acid. The first silver(i) yttrium double molybdate, AgY(Mo04)2, has been reported. ... 

ACRYLIC ACID, 2-ETHYLHEXYL-ESTER (103-11-7) CnHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 0.8 to 6.4 flashpoint 180°F/82°C oc autoignition temp 496°F/258°C Fire Rating 2]. Unless inhibited, contact with heat, sunlight, contaminants, or peroxides may cause hazardous polymerization. Reacts violently ivith strong oxidizers, with risk of fire and explosions. Incompatible with strong acids, alkalis, aliphatic amines, alkanolamines, nitrates. The uninhibited monomer vapor may block vents and confined spaces by, forming a solid polymer material. On small fires, use AFFF, foam, dry chemical, or COj extinguishers.
