2-Ethylhexyl nitrate Usage And Synthesis

Chemical Properties

solid

Uses

2-Ethylhexyl nitrate (2-EHN) is a major fuel additive, has been used to increase the cetane number of diesel.

General Description

Biodegradation of 2-ethylhexyl nitrate (2-EHN) by Mycobacterium austroafricanum IFP 2173 has been studied. Biodegradation of 2-EHN was studied in biphasic liquid cultures using an inert non-aqueous phase liquid such as 2,2,4,4,6,8,8-heptamethylnonane as solvent.

Flammability and Explosibility

Not classified

Synthesis

A production method of 2-Ethylhexyl nitrate, the steps are: (1) 1500L reactor add 100 kg of 98% nitric acid, water cooling, vigorous stirring under the addition of 424 kg of 87% sulfuric acid, made of sulfuric acid and nitric acid acid mixture; (2) 156 kg of isooctyl nitrate to 195 kg of iso-octanol and mix it well; (3) (2) isooctyl nitrate and iso-octanol mixture prepared by adding to the (1) mixed acid. (3) The mixture of isooctyl nitrate and isooctanol prepared in (2) was added to the mixed acid prepared in (1), the process of adding speed control to keep the reaction temperature between 10-30 ??, add the stirring reaction for 45 minutes, static liquid separation, organic phase alkali washing, water washing, to obtain the product of isooctyl nitrate purity of 99.1%, the yield of 98.2%.
