| titleOfInvention | Process for purifying streams comprising 1,4-butanediol |
| abstract | A process for purifying a stream comprising 1,4-butanediol, comprising: (a) 1,4-butanediol and γ-butyrolactone, 2- (4-hydroxybutoxy) -tetrahydrofuran, 4-hydroxybutyl (4 Supplying a crude product stream comprising one or more of -hydroxybutyrate) and 3- (4-hydroxybutoxy) -tetrahydrofuran to the first distillation column; (b) 1,4-butanediol And a side draw comprising light components, wherein the light components comprise at least a portion of what is produced by the reaction in the first distillation column, and (c) sending the stream to the hydrogenation zone And (d) subjecting the stream from step (c) to hydrogenation in the presence of a hydrogenation catalyst in the hydrogenation zone, Including (4-hydroxybutyl) -4-hydroxybutyrate with reduced 2- (4-hydroxybutoxy) -tetrahydrofuran content and optionally additionally formed by reaction of γ-butyrolactone, 1, Recovering the 4-butanediol product stream, and (e) removing the 1,4-butanediol product stream from step (d) as the bottom stream of (4-hydroxybutyl) -4-hydroxybutyrate. To the second distillation column operated as described above, and removing the 1,4-butanediol stream as a top distillate, and (f) the top stream removed in (e) to the third distillation column Feeding and recovering the purified 1,4-butanediol stream. |
