Abstract
A process for producing an omega-functionalized aliphatic carboxylic acid starting from cyclohexanone and omega-functionalized .alpha.-olefins. The process comprises an addition step, an oxidation step, an isomerization step, one or more hydrogenation steps and hydrolysis. The process allows to use raw materials that are available at low cost and to achieve high selectivity and high yield with industrially simple steps. The process includes the production of new intermediate products.
