To obtain 3% 2C4% 2C3% 27% 2C4% 27 - tetraphenyl - 1% 2C1% 27 - ethanediylbispyrol - 2% 2C5 - dione, there are many methods, and one of them is described below.
First take an appropriate amount of benzaldehyde and place it in a clean reactor. Dissolve in an appropriate organic solvent, such as dichloromethane or toluene, to disperse benzaldehyde uniformly. Add a certain amount of diethyl malonate, and the ratio of the two needs to be precisely prepared to achieve the best reaction effect. The two are the main ingredients of the reaction, and the ratio is related to the purity and yield of the product.
Then add an appropriate amount of catalyst, such as piperidine or pyridine and other organic bases. The amount of catalyst should not be too much or too little. If it is too much, the reaction will be too fast and difficult to control; if it is too little, the reaction will be slow and time-consuming. The catalyst can effectively reduce the activation energy of the reaction and promote the progress of the reaction.
When reacting, the temperature and reaction time should be strictly controlled. Heat in a water bath or an oil bath to maintain the temperature within a specific range, generally about 60 to 80 degrees Celsius. The reaction time also needs to be precisely controlled, about 6 to 8 hours. During this period, stirring should be continued to fully contact the reactants to accelerate the reaction process.
After the reaction is completed, the reaction mixture is cooled to room temperature. Then, with an appropriate acid solution, such as dilute hydrochloric acid, acidification treatment is carried out to precipitate the product from the solution. The precipitated product can be obtained by suction filtration or centrifugation.
The crude product still contains impurities and needs to be further purified. By recrystallization, select a suitable solvent, such as ethanol or ethyl acetate, etc., to recrystallize the crude product. After multiple recrystallization, high purity 3% 2C4% 2C3% 27% 2C4% 27 - tetraphenyl - 1% 2C1% 27 - ethanediylbispyrol - 2% 2C5 - dione product can be obtained.
This is only one of the methods. In actual preparation, or due to differences in raw materials and equipment, the method has been adjusted and optimized to achieve the ideal preparation effect.
