Study on New Technology for Recovery of Maleic Anhydride Ⅰ.Thermal Dehydration Process |
| |
| Abstract: | A process for recovering maleic anhydride by thermal dehydra tion is pre-sented.The process consists of concentration by evaporation of aqueous maleicacid to 65%,conversion of the dehydrated maleic acid into gaseous maleicanhydride and water vapor,and condensation of the superheated gas bycooling it to a temperature above the dewpoint of water.Maleic anhydridewith a purity of over 98% is obtained. |
