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 |
<p>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.</p> |
