| titleOfInvention | PROCESS TO PURIFY A CURRENT UNDERSTANDING 1,4-BUTANODIOL |
| abstract | PROCESS TO PURIFY A CURRENT UNDERSTANDING 1,4-BUTANODIOL. A process for the purification of a stream comprising 1,4-butanediol, comprising the steps of: (a) supplying a crude product stream comprising 1,4-butanediol and one or more of? -Butyrolactone, 2- ( 4-hydroxybutoxy) -tetrahydrofuran, 4-hydroxy-butyl (4-hydroxybutyrate), and 3- (4-hydroxybutoxy) -tetrahydrofuran for a first distillation column; (b) removing a side drain comprising 1,4-butanediol, and light components, than said light components, including at least some of the products produced by reacting the first distillation column; (c) the passage of the current to a hydrogenation zone; (d) subjecting the stream from step (c) to hydrogenation in the hydrogenation zone in the presence of a hydrogenation catalyst, and recovering from the hydrogenation zone a stream of 1,4-butanediol product with a content reduced from 2- (4-hydroxybutoxy) -tetrahydrofuran, and optionally additionally including (4-hydroxybutyl) -4-hydroxybutyrate formed by? butyrolactone reaction; (e) passage of the 1,4-butanediol product stream from step (d) to a second distillation column, operated in such a way that (4-hyroxybutyl) -4-hydroxybutyrate is removed as a bottom stream and removing a 1,4-butanediol current as an overload; and (f) start to (...). |
