Title: A Process for the Preparation of Acetic Acid by Means of the Oxidation of Acetaldehyde.
IPC: C07C51/235
Filed: 1918-02-28
Abstract: 130,651. Compagnie des Produits Chimiques d'Alais et de la Camargue. March 6, 1917, [Convention date]. Acetic acid.-In the production of acetic acid by the oxidation of aldehyde vapour by air or oxygen in towers in the absence of a catalyst, accumulation of peracetic acid in the towers is prevented by providing a supplementary heating- chamber below the towers, into which the liquid acetic acid falls, carrying with it any peracetic acid present, which then decomposes. Using the apparatus shown, a current of aldehyde entering by a pipe A, and a current of oxygen or air entering by a pipe C mix in the vessel B and pass to a decomposing-vessel E kept at about 100‹ C. by a steam jacket F; the gaseous mixture then flows into an oxidation tower H packed with quartz, broken glass, &c. and provided with a water jacket K; the liquid acetic acid formed, together with any undecomposed peracetic acid, drops into the vessel E, in which the peracetic acid decomposes. The gaseous mixture from the tower H passes on to similar towers L, L<1>, L<2>, in which most of the remaining aldehyde is oxydized; the liquid products from these towers pass by the pipes O. P, Q. S, B, D, and a liquid seal M, to the vessel E; the seal M is also steam-jacketed to prevent any accumulation of peracetic acid therein. The gases finally pass to a reflux condenser R, any condensed aldehyde returning to the plant by pipe S, and the last traces of aldehyde are absorbed by acetic acid in a tower T, the solution flowing back to the plant by pipe V. A flank W through which the gases exhaust serves to indicate the rate of gas-flow. From the vessel E, the acetic acid flows through a series of vessels X, Y, through which the entering current of air or oxygen bubbles to remove aldehyde, and the pure acetic acid flows off by a pipe Z. Specifications 17424/11, 8076/12, 16849/13, 17016/13, and 7418/14 are referred to.
