摘要：NOVELTY - This invention has disclosed a manufacturing method to binuclear tricarbonyl chromium complex. It adopts single-nuclear tricarbonyl chromium complex as raw materials, one kind or many kinds of mixture of dioxane, tetrahydrofurans, butylether as medium, deoxidize with standard Schlenk technology, under the condition of mixing, when the temperature is 50-150 deg.C, sealed heating 20 -40 hours, precipitate reaction products with petroleum ether, get binuclear tricarbonyl chromium complex finally. Production ratio of binuclear tricarbonyl chromium complex is up to 30 percent.
