Hydrochloric Acid → Gamma-Butyrolactone

Participants

Reaction Steps

Crude 4-chlorobutyric acid (CBA) was produced, in a known manner, by introducing gaseous hydrogen chloride into γ-butyrolactone (BL), at 100° C., until hydrogen chloride was no longer taken up. Subsequently, nitrogen was passed through the reaction mixture, in order to expel excess hydrogen chloride. The acid number was then 393. 1,818 g crude CBA was obtained from 1,373 g (15.8 mol) of BL.
