| titleOfInvention | The method of Epoxidation of Dicyclopentadiene preparative separation bicyclopentadiene dioxide |
| abstract | The method of Epoxidation of Dicyclopentadiene preparative separation bicyclopentadiene dioxide, dicyclopentadiene is in the presence of reaction-controlled phase-transfer phosphorus heteropoly tungstic acid salt catalyst and auxiliary agent EDTA, dimethyl carbonate is solvent, directly generates bicyclopentadiene dioxide with hydrogen peroxide for oxidant reactionï¼›After reaction terminates the cooling of gained reactant liquor, solid catalyst in reactant liquor reclaims Posterior circle and uses, organic facies removed under reduced pressure solvent after activated carbon filters i.e. obtains bicyclopentadiene dioxide, present invention process simplifies, technological process is short, can be effectively reduced production cost, and energy consumption is low, environmentally friendly, product separating-purifying is simple and convenient. |
