Method for producing propylene glycol from propene and hydrogen peroxide |
| abstract |
The invention relates to a method for producing propylene glycol from propene and hydrogen peroxide, comprising the following steps: a) reacting propene with hydrogen peroxide in the presence of a catalyst mixture comprising a phase transfer catalyst and a heteropolytungstate, wherein the reaction is carried out in a fluid mixture comprising an aqueous phase with a maximum pH of (6) and an organic phase; b) dividing the two-phase mixture from step a) into an aqueous phase and an organic phase containing propylene oxide; c) returning the propylene oxide contained in the separated organic phase into the reaction from step a); and d) separating propylene glycol from the aqueous phase separated in step b). |
