| titleOfInvention | Method for microwave solid-phase synthesis of tetrabenzoporphyrin zinc (II) |
| abstract | The invention discloses a method for microwave solid-phase synthesis of tetrabenzoporphyrin zinc (II), which comprises the following preparation steps: (1) weighing malonic acid, potassium phthalimide and zinc acetate, mixing and grinding to obtain mixed powder; (2) irradiating the mixed powder by using microwave until the reaction is completed to obtain a reactant; (3) cooling the reactant away from light, and performing column chromatography separation to obtain the product. The invention has the beneficial effects that: (1) the reaction is carried out in a solid phase, the reaction environment is loose, the reaction condition limitation is small, and the applicability is strong; (2) the microwave three-dimensional heating reaction is adopted, so that the reaction time is effectively shortened, the reaction energy barrier is reduced, the heat sublimation phenomenon is avoided, and the yield is improved; (3) the reaction does not need a solvent, so that the use and the recovery of the solvent can be avoided, and the cost is reduced; (4) no solvent participates in the reaction, which is beneficial to purification. |
