In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 34595-26-1, name is 2-(Piperidin-1-yl)benzaldehyde, introducing its new discovery. Safety of 2-(Piperidin-1-yl)benzaldehyde
The synthesis of 2,3,4,4a,5,6-hexahydro-6H-spiro[benzo[c]quinolizine-5, 4?-pyrazol]-5?-ones has been achieved by the reaction of 2-piperidinobenzaldehydes with 2-aryl-5-methyl-2,4-dihydropyrazol-3-one via the “tert-amino effect” mechanism.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 34595-26-1 is helpful to your research. Safety of 2-(Piperidin-1-yl)benzaldehyde
