Title: Improvements relating to the production of maleic anhydride
IPC: C07C51/56
Filed: 1952-09-19
Abstract: A process for the production of maleic anhydride comprises passing an aqueous maleic acid solution containing not more than 85 per cent by weight of water into a series of tubes heated above the boiling temperature of the material therein at rates such that the liquid passing through the tubes is only partially evaporated, only partially cooling the liquid and vapour from each tube and separating the resulting liquid from the vapour, passing the liquid into the next tube in the series, condensing and removing the vapour from the first separation, and condensing the vapour from each subsequent separation and mixing the condensate with the liquid entering the tube preceding the one in which the vapour was formed and continuing the alternate partial evaporation and partial condensation until a commercially pure maleic anhydride is obtained.  The aqueous maleic acid solutions employed as starting materials may be those obtained by scrubbing gases from the catalytic vapour phase oxidation of aromatic hydrocarbons, e.g. naphthalene or benzene, or phenol. Preferably a system containing at least three heating tubes may be employed but two partial vaporizing steps each followed by partial condensation and separation may be employed.
