| titleOfInvention | PROCESS TO PURIFY A JET THAT INCLUDES 1,4-BUTANODIOL. |
| abstract | A process for purifying a jet comprising 1,4-butanediol comprising the steps of: (a) providing a jet of raw product comprising 1,4-butanediol and one or more of y-butyrolactone, 2- (4- hydroxybutoxy) -tetrahydrofuran, 4-hydroxybutyl (4-hydroxybutyl irate), and 3- (4- hydroxybutyloxy) -tetrahydrofuran to a first distillation column; (b) removing a side drawer comprising 1,4-butanediol, and light components, said light components including at least some of those produced by means of the reaction in the first distillation column; (c) passing the jet to a hydrogenation zone; (d) subjecting the jet of step (c) to hydrogenation in the hydrogenation zone in the presence of a hydrogenation catalyst, and recovering a 1,4-butanediol product from the hydrogenation zone having a reduced content of 2 - (4-hydroxybutyloxy) -t etrahydrofuran, and optionally additionally including (4-hydroxybutyl) -4-hydroxybutyrate formed by the reaction of y-butyrolactone; (e) passing the jet of 1,4-butanediol product from step (d) to a second hydrogenation column operated in such a way that (4-hydroxybutyl) -4-hydroxybutyrate is removed as a lower jet and eliminating a jet of 1,4-butanediol in higher form; and (f) passing the upper jet removed in (e) to a third distillation column and recovering a stream of purified 1,4-butanediol. |
