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, 143900-44-1, name is (S)-tert-Butyl 3-hydroxypiperidine-1-carboxylate, introducing its new discovery. Safety of (S)-tert-Butyl 3-hydroxypiperidine-1-carboxylate
The invention relates to a according to lu tini and its key intermediate for the preparation of the new method, the existing synthetic process avoids the more stringent reaction conditions, and the expensive starting material and reagent. The oxide by a one-pot reaction synthesis of key intermediate, simplified post-processing operation is relatively complex, and the cost is reduced. The obtained intermediate purity of 99% or more, the yield is higher, the operation is simple, and is suitable for industrial production. (by machine translation)
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 143900-44-1 is helpful to your research. name: (S)-tert-Butyl 3-hydroxypiperidine-1-carboxylate
