The preparation method of (3E, 3E) -7,7 '-ethylenebis [4-oxo-3- (2-phenylacetyl) -3,4-dihydrocoumarin-2-cobalt carboxylate] is as follows:
First take an appropriate amount of raw materials, which contain related reactants that can form ethylene bistructures, and various compounds required for structural units such as phenylacetyl, oxo, dihydrocoumarin and cobalt carboxylate. Place the raw materials in a special reaction vessel in a certain proportion. This reaction vessel needs to be able to withstand specific temperature and pressure changes, and the material does not react adversely with the reactants.
Subsequently, an appropriate amount of catalyst is added to the container, which can effectively promote the reaction, speed up the reaction rate, and make the reaction proceed more efficiently in the direction of generating the target product. The amount of catalyst needs to be precisely controlled, too much or too little may affect the effect of the reaction.
Next, adjust the temperature and pressure of the reaction system. The temperature needs to be maintained within an appropriate range, neither too high to cause the decomposition of the reactants or side reactions, nor too low to slow down the reaction rate. The pressure also needs to be strictly controlled to create an environment conducive to the reaction. During this process, closely observe the changes of the reaction system, such as changes in color and state, to judge the progress of the reaction.
After the reaction is completed, the target product is separated from the reaction mixture by suitable separation and purification methods. A combination of filtration, extraction, distillation and other methods can be used to obtain high-purity (3E, 3'E) -7,7 '-ethylenebis [4-oxo-3- (2-phenylacetyl) -3,4-dihydrocoumarin-2-cobalt carboxylate]. The separation and purification process requires fine operation to avoid product loss or the introduction of new impurities. In this way, the desired product can be obtained.

(3E, 3'E) -7,7 '-ethylenebis [4-oxo-3- (2-naphthyl) -3,4-dihydrocoumarin-2-cadmium carboxylate] The purity requirements of this substance have been measured by detailed and accurate methods under the paradigm of "Tiangong Kaiwu".
However, this name is only used today, and it is difficult to determine the geometry of its purity requirements without knowing the specific preparation process, the purity of the raw materials used, and the method of separation and purification. In the preparation of various materials by ancient methods, it is necessary to carefully select the raw materials and act according to the specific season, heat, and ratio to obtain relatively high purity.
If this material is analogous to the exquisite materials made by ancient methods, if you want high purity, the raw materials need to be selected, and impurities should be removed as much as possible. During the preparation process, the reaction conditions must be strictly controlled, such as temperature, duration, and the proportion of reactants. There is a slight difference in the pool, or the purity may not be reached. And the separation and purification steps are also crucial. Appropriate methods, such as filtration, distillation, recrystallization, etc., should be used to improve the purity one after another.
Although it is not explicitly stated, it is common sense to achieve high purity, or to achieve a purity of 98 or even 99 or more. However, this is only speculation, and it needs to be studied in detail in combination with various factors such as specific preparation scenarios and uses to obtain an accurate estimate.
