A process for separating reaction mixtures and recycling quaternary salts and bases |
abstract |
A process for the removal and recovery of quaternary salt (A) and base (D) from a reaction mixture is disclosed. The reaction mixture resulting from oxidative direct carbonylation contains in addition to (A) and (D), at least one hydroxyaromatic compound (B) and at least one reaction product (C) and optionally a solvent, and the process entails (a) adding acid to the reaction mixture to cause conversion of (D) into a hydroxyaromatic compound (B2) (b) separating the reaction mixture into b1.) that contains (C) and optionally (B) and/or (B2) and b2.) that contains (A) and optionally (B) and/or (B2), and (c) reacting b1.) with a base (E) to re-form (D). |
