The present invention relates to a method for production of p-cymene from cyclic monoterpenes in the presence of an Fe(III)-salt as a catalyst. In particular it relates to a method for production of p-cymene from cyclic monoterpenes containing high levels of sulphur, such as crude sulphate turpentine. The method can be performed as two different, subsequent processes for the isomerization and oxidation reactions, or in a single process wherein these reactions take place at the same time.
