AB: The reaction between molten potassium and carbon monoxide (without solvent) has been studied. The reaction products obtained have been shown to be a mixture of potassium acetylenediolate, an organometallic compound, and the potassium salt of hexahydroxybenzene, the relative amounts of which vary with temperature. At reaction temperatures near the melting point of potassium (62,3°), potassium acetylenediolate and the organometallic compound are the major products, whereas at temperatures higher than 180° the potassium salt of hexahydroxybenzene predominates.
