In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 538-58-9,1,5-Diphenylpenta-1,4-dien-3-one, as follows.538-58-9
538-58-9, Step 1. Under a nitrogen atmosphere, add 8 L of absolute ethanol and 0.112 kg of anhydrous sodium acetate to a glass reactor heated in a water bath.When the system temperature was heated to 68 C, 0.92 kg of dibenzylideneacetone obtained in Example 1 was added.After stirring for 30 minutes, add ice to the water bath heater to quickly cool the system down to 60 C.Then, 0.2 kg of palladium dichloride prepared in Example 1 was added and reacted at 60 C for 2 hours.Funnel filtration gave bis (dibenzylideneacetone) palladium (0);
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 538-58-9, We look forward to the emergence of more reaction modes in the future.
