Abstract
1455593 Working up nitration mixtures BASF AG 4 April 1974 [6 April 1973] 14918/74 Heading C2C The invention comprises a process for working up a reaction mixture obtained by nitration of an aliphatic or cycloaliphatic ketone, in the presence or absence of the corresponding alcohol, with at least 95% w./w. nitric acid in the presence of an inert organic solvent for the organic compounds, wherein there is added to the reaction mixture a nitric acid of a concentration such that the reaction mixture contains 40 to 80% w./w. nitric acid prior to the separation of the organic phase. The nitric acid to be added to the reaction mixture following nitration generally has a strength of from 40 to 70% w./w. Working up is advantageously carried out at a temperature of less than 50‹ C. Magnesium nitrate may be added to the reaction mixture following nitration in order to diminish further the residual concentration of organic material in the aqueous nitric acid phase. Example 2 also describes the preparation of #-nitro capronamide by passing ammonia through 2-nitrocyclohexanone.
