| titleOfInvention | Process for the preparation of alkyl nitrobenzoates |
| abstract | A process for the preparation of alkyl (C 1 -C 3 ) nitrobenzoates by reacting the nitrobenzoic acid to be esterified with an excess of about 300 to about 600 mol % of an alkanol (C 1 -C 3 ) in a solvent which is inert towards the starting compounds and the reaction product in the presence of a polyfluoroalkanesulfonic acid of the general formula (1) n n Y(C.sub.n F.sub.2n)SO.sub.3 H (1) n n in which Y is a hydrogen or fluorine atom, with the proviso that, if Y is H, this hydrogen atom is in the β-position relative to the sulfo group, or the hydrate thereof as catalyst in an amount of about 0.1 to about 20 mol %, relative to the nitrobenzoic acid used, at temperatures from about 60° to about 120° C. |
