| use | organic reaction catalyst. Additives. A drier for paint. Paint pigment. Vapor plating cobalt. It is used to synthesize a new monoporphyrin (monoporphyrinates) family. It is of great significance to study the photochemical and applied magnetic properties and synthetic applications of this family. Organic reaction catalyst; used to prepare new monoporphyrin series compounds, which are used in photochemistry, magnetism, and synthesis fields |
| production method | 4.5g basic cobalt carbonate (ii) and 40mL(0.4mol) acetylacetone are placed in a 200mL beaker and heated to 90~100 ℃. 60mL 10% hydrogen peroxide solution was added dropwise under vigorous stirring. Pay attention to prevent the reaction from being too intense. About 45min, after dropping H2O2 solution. At the end of the reaction, the solution is dark green, and green solids are precipitated. Cool with ice salt bath, filter and separate solids, and dry at 110 ℃. Then dissolve the solid with 50mL boiling benzene, add 300mL heptane or petroleum ether while it is hot, cool and filter, and naturally dry to obtain 10~12g of product with a yield of 67% ~ 80%. |
