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. Computed Properties of C11H13N
The present invention relates to heptamethine hemicyanine chromophores of formula (I): where R1, R2, R3, R4, R?4, R5, R?5, R6, R?6, R7, X, Y1 and Y2 are as defined in claim 1, to the method for preparing same as well as to the use of such chromophores for the second-order nonlinear optical property thereof.
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. Computed Properties of C11H13N
