METHOD OF PRODUCING ALKANEPHOSPHONIC ACIDS 2,2,2-TRINITROETHYL ESTERS Russian patent published in 2016 - IPC C07C303/26

Abstract SU 1841126 A1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing alkanephosphonic acids 2,2,2-trinitroethyl esters, for example, ethanesulfonic acid, with application of 2,2,2-trinitroethanol derivatives as esterifying agent, characterised by that, in order to simplify method and providing its safety, esterification is subjected to appropriate acid, for example, ethanesulfonic acid, using aqueous trinitroethanol sulphate followed by separating end product using known techniques.

EFFECT: simplification of a method and providing its safety.
