IPC: C07D307/60
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a simple method for cleaning a distilling equipment for producing maleic anhydride. SOLUTION: This method for cleaning a distilling equipment for producing maleic acid anhydride, in which maleic acid or maleic acid anhydride obtained by catalytic vapor phase oxidation reaction is captured in an aqueous solvent and the resultant maleic acid-containing aqueous solution is concentrated and/or dehydrated, is characterized in that the maleic acid-containing aqueous solution added by an oxidant is concentrated and/or dehydrated in the equipment and after that water or an aqueous solution is added in the equipment. According to this invention, the inside of the equipment is remarkably efficiently cleaned by a simple operation of solely adding water owing to a finding that the generation of resin-like or gel-like materials is suppressed by the addition of the oxidant and that adhered materials remaining in the equipment are brought to be water soluble.
