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, 177-11-7, name is 1,4-Dioxa-8-azaspiro[4.5]decane, introducing its new discovery. Product Details of 177-11-7
The present invention relates to compounds according to formula (I), a process for preparing them, the intermediate compounds of the process and the use of the compounds in the manufacture of a medicament for use in treating diseases such as ARDS, pulmonary emphysema, bronchitis, bronchiectasis, COPD, asthma and rhinitis. The compounds are beta2 adrenoreceptor agonists.
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 177-11-7 is helpful to your research. Product Details of 177-11-7
