Abstract
FIELD: catalysts in industrial organic synthesis. SUBSTANCE: method involves treatment of reaction solution with hydrogen at 60-70 C followed by separation of precipitated palladium and further separation of acetoxylation products and catalyst components and is distinguished by that, in order to reuse active components of catalyst for the same reaction, reaction solution, prior to be separated, is supplemented with 10-15 wt % of tetraethylene glycol. EFFECT: enabled reutilization of active components of catalyst.
