Abstract

Procedure for obtaining lactates, by transposition of cycloalkanone oxides, at a temperature between 210 and 450ºC, with catalysts on supports containing boric acid, in a fluidized bed, characterized in that together with or separated from the cycloalkane oxime, it is introduced, in the fluidized bed an aliphatic or cycloaliphatic hydrocarbon, an aromatic hydrocarbon optionally substituted by halogen atoms and/or a nitro group, or the lactam.
