    摘要: A process is disclosed for the recovery of high purity squaric acid from squarate containing solids from the electrochemical cyclization of carbon monoxide, involving contacting the squaric acid containing product with a two-phase mixture of strong, nonoxidizing aqueous acid and an immiscible organic solvent, followed by separating the solid, substantially pure squaric acid from the resulting three-phase mixture.
