| titleOfInvention | Method for synthesizing methyl phosphorus dichloride based on carbon microsphere loaded iron-nickel-cerium catalyst |
| abstract | A method for synthesizing methyl phosphorus dichloride based on a carbon microsphere loaded iron-nickel-cerium catalyst comprises the steps of preparation of impregnation liquid, preparation of the carbon microsphere loaded iron-nickel-cerium catalyst and synthesis of methyl phosphorus dichloride; the synthesis method adopts a carbon microsphere loaded iron-nickel-cerium catalyst, wherein the loading amount of the iron-nickel-cerium ternary element accounts for 0.2-1% of the total mass of the carbon microsphere carrier, and the molar ratio of iron-nickel-cerium atoms loaded into the carbon microsphere is 49-62: 29-48: 3-9. The method has the advantages that the reaction temperature is low, 300-400 ℃, the conversion rate of phosphorus trichloride is 20.4-30.1%, the yield of methyl phosphorus dichloride is 94.6-97.5%, the catalyst is solid, is nontoxic and easy to separate from a reaction system, the service life is 2800-3400 hours, and 3.6-6.5 kg of methyl phosphorus dichloride can be produced by each gram of carbon microsphere loaded iron-nickel-cerium catalyst. |
