process for the production of dialkyl succinate from maleic anhydride |
| abstract |
patent abstract for: "process for producing dialkyl succinate from maleic anhydride". a process for producing dialkyl succinate from a feedstock comprising maleic anhydride, said process comprising the steps of providing liquid phase feed to a reactor operated at a temperature of at least about 150°C; contacting said feed with hydrogen at a pressure of at least about 300 psig in the presence of an acid tolerant catalyst and an alkanol wherein at least part of the carbon-carbon double bonds of maleic anhydride are hydrogenated to form succinic acid and that the generated heat promotes esterification to on-site dialkyl succinate; and recovering a stream comprising dialkyl succinate from the reactor. |
