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, 2213-43-6, name is 1-Aminopiperidine, introducing its new discovery. Computed Properties of C5H12N2
The saturated heterocyclic compounds C4H8Y, C 5H10Y, and C5H10Y2 (Y = Se or Te) have been prepared by the reaction of 1,4-dibromobutane or 1,5-dibromopentane with potassium chalcogenides. The novelty of the route consists of the use of the hydrazine hydrate-KOH system for the reductive generation of potassium selenide, telluride, diselenide or ditelluride from elemental chalcogens.
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 2213-43-6 is helpful to your research. Computed Properties of C5H12N2
