A kind of synthetic method of our organic compound chemical piperidine CAS28578-16-7 on sale

The direct synthesis of this chemical uses a modified Wacker method, which originally referred to the oxidation of ethylene to acetaldehyde with oxygen in the air in water containing a palladium tetrachloride catalyst. Under the action of WACKER catalysts, terminal olefins, internal olefins and cyclic olefins with high carbon numbers can also be converted. However, due to the steric effect of the olefin structure and the isomerization of the palladium-catalyzed reaction, the yield of the reaction product is much lower than that of the ethylene oxidation product. To improve the catalytic effect of WACKER catalysts, we can start with the selection of suitable cosolvents, oxidants, and palladium complexes. Some people also use safrole as raw material, methanol as solvent, benzoquinone as oxidant, and palladium chloride as a catalyst to directly synthesize the organic chemical piperidine ketone CAS28578-16-7.

Synthesis of Valerophenone CAS: 1009-14-9 we sell

To obtain this organic chemical, a series of operations and reactions are required. In a 500 mL dry three-necked flask with a sealed stirring device, a thermometer, a dropping funnel, a condenser, and an absorption device, 36.25 g of o-chlorobenzoyl chloride and 112 g of dichloroethane were first added, cooled to 10 °C, and then Add 31.25 grams of anhydrous aluminum trichloride and maintain this temperature. The overflow was lowered to -20 °C and the ring, a mixture of 17.5 g of pentene and 31.5 g of dichloroethane was added dropwise. The reaction temperature was kept at 20~-25°C, and the dropwise addition was completed within 3.5~4 hours, at which time the reaction solution changed from orange to red.

Then 31.5 grams of dichloroethane was added and stirred for 30 minutes. Then, 40 g of cyclohexane was added at -15° C., and the remaining half of 31.25 g of aluminum trichloride was slowly added to the second half, and the addition was completed within 1 h. After the addition, the temperature was allowed to rise and the vacuum was opened to absorb the hydrogen chloride. The temperature was controlled at 10 to 15 °C for the first 2 to 3 hours, and the temperature was raised to 35 °C after 1 to 2 hours until the hydrogen chloride was consumed and the reaction was completed.

The reaction organic chemical solution was cooled to room temperature, crushed ice was added, and the mixture was slowly and intermittently stirred to separate the organic layer. The aqueous layer was extracted twice with 50 mL of dichloromethane, the aqueous layer was discarded, and the organic layers were combined. The organic layer was washed 4 times with 120 mL of water, the aqueous layer was separated and discarded, and dried over anhydrous ferric sulfate overnight. The next day, diaminoethane was recovered at atmospheric pressure.
