METHOD FOR OBTAINING 2-ETHYLHEXYLNITRATE Russian patent published in 2018 - IPC C07C201/02 C07C203/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the method for obtaining 2-ethylhexylnitrate (2-EHN) by the nitration of 2-ethylhexanol with a mixture of sulfuric and nitric acids, the separation of the acid product followed by washing. As a sulfuric-nitric acid mixture, a mixture of the composition is used, wt % HNO₃ - 21-33%, H₂SO₄ - 55-63%, H₂O - the rest to 100%, the nitration with a sulfuric-nitric acid mixture is carried out at a temperature of 15-25°C without the use of the stabilizing additives, washing is carried out once with 3-10% solution of NaOH at room temperature and the mass ratio of the product solution of 1:0.3 to 1:0.1, with subsequent destruction of the formed emulsion 2-EHN/water.

EFFECT: method allows to carry out the nitration without any stabilizing additives, to reduce the consumption of reagents and the amount of wash water, and to increase the productivity.
