NOVELTY - Preparation of (3,3-dimethyl-1-butyne)hexacarbonyl dicobalt, involves adding a cobalt carbonyl reagent and 1500-2000 parts mass hydrocarbon solvent to a reactor under nitrogen protection atmosphere, controlling the temperature at 0-30 degrees C, slowly adding 0.1-0.8 part mass ionic-liquid-modified graphene oxide material and 20-30 parts mass t-butylacetylene, stirring and reacting under nitrogen protection for 1-10 hours, filtering, distilling the filter liquid and removing the volatile components to obtain a crude product, and purifying the crude product. USE - Preparation of (3,3-dimethyl-1-butyne)hexacarbonyl dicobalt. ADVANTAGE - The method enables preparation of (3,3-dimethyl-1-butyne)hexacarbonyl dicobalt carbonyl with strong operability, less reaction byproduct generation, and high yield.
