Production of propargyl alcohol used e.g. as pesticide intermediate, involves converting aqueous formaldehyde solution containing acetylene and organic solvent in presence of fluidized catalyst containing copper acetylide

摘要

In the production of propargyl alcohol (I) by conversion of an aqueous formaldehyde solution containing acetylene in presence of a catalyst containing copper acetylide at 1-15 (preferably 3-7) bars and 70-120[deg]C without formation of a coherent gas phase, the aqueous formaldehyde solution contains an organic solvent for acetylene and the catalyst is arranged in a fluidized bed.
