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, 1640-39-7, name is 2,3,3-Trimethylindolenine, introducing its new discovery. Application In Synthesis of 2,3,3-Trimethylindolenine
Spironaphth[1,2-b]oxazines having either an allyl group or a 3-(diethoxymethylsilyl)propyl group on the N-atom of the indoline ring have been prepared, as potential substrates for photochromic materials. In addition to displaying the well-known photochromism between the closed and open forms, the present spirooxazines exhibit photochromism between two geometric isomers of the colored open form. This behavior provides the basis for a non-destructive read-out system having light-induced information memory.
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 1640-39-7 is helpful to your research. Application In Synthesis of 2,3,3-Trimethylindolenine
