| titleOfInvention | PROCESS FOR THE PRODUCTION OF 1,4-BUTANODIOL |
| abstract | A process for the production of dialkyl succinate from a bio-succinic acid raw material comprising the steps of: (a) feeding solid bio-succinic acid to a first reactor where it is contacted with alkanol, said first reactor it is operated at a suitable temperature and pressure to allow autocatalytic esterification to occur; (b) passing a current removed from the first reactor comprising unreacted succinic acid, monoalkyl ester, dialkyl ester, alkanol, water and the impurities at a point at or near the top of an area of the column of reaction that operates at temperatures and pressures that allow the esterification of succinic acid and subsequent esterification of the monoalkyl ester; and passing said current in countercurrent reaction to the additional upstream alkanol; (c) removing a current from or near the bottom of the zone of the reaction column comprising components selected from residual succinic acid, monoalkyl ester, dialkyl ester, impurities and alkanol; and passing said current to a current separation zone where said dialkyl ester is separated from the alkanol, and from the succinic acid, monoalkyl ester and impurities; (d) recycle the succinic acid and monoalkyl ester to the zone of the reaction column; (e) remove at least some of the impurities as a purge; and (f) removing a stream comprising alkanol, water and organic components from -or near the top of the reaction column area; passing said stream to a distillation zone of the upper stream where the alkanol is separated from the water and the organic components; and recycle the organic components to the zone of the reaction column. |
