Patent

CA 2440164

A method and apparatus for the production of ketones via a one-step synthesis from aldehydes. In the method of the invention, an aldehyde, a carboxylic acid, and a source of oxygen, such as water, are allowed to react in the vapor phase in a catalytic tube reactor. Asymmetrical ketones, such as methyl cyclopropyl ketone, are particularly desirable reaction products.

L'invention concerne un procédé et un appareil permettant de produire des cétones à partir d'aldéhydes à l'aide d'une synthèse en une étape. Selon le procédé de cette invention, un aldéhyde, un acide carboxylique et une source d'oxygène telle que de l'eau sont mis en réaction en phase vapeur dans un réacteur à tube catalytique. Des cétones asymétriques, telles que la méthylcyclopropylcétone, sont des produits de réaction particulièrement recherchés.
