In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C17H14O, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. In an article£¬Which mentioned a new discovery about 538-58-9
Catalysis by ionic liquid: A simple, green and efficient procedure for the Michael addition of thiols and thiophosphate to conjugated alkenes in ionic liquid, [pmIm]Br
A room temperature ionic liquid, 1-pentyl-3-methylimidazolium bromide, [pmIm]Br efficiently catalyzes Michael addition of thiols and diethyl dithiophosphate to a variety of conjugated alkenes such as alpha,beta- unsaturated carbonyl compounds, carboxylic esters, nitriles and chalcones without requiring any other organic solvent and catalyst. The ionic liquid can be recycled for subsequent reactions without any appreciable loss of efficiency.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 538-58-9, help many people in the next few years.Formula: C17H14O
