One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C8H5ClN2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2
A fragrant nitrile or heteroaromatic nitrile compound preparation method (by machine translation)
The invention discloses a fragrant nitrile or heteroaromatic nitrile compound preparation method, the method comprises the following steps: under protection of inert gas, in a solvent, in the nickel catalyst and ligand, metal zinc, and under the action of the additive, the cyano reagent with a halo aromatic hydrocarbon or the halogenating is mixed aromatic hydrocarbon reaction can be. The present invention provides a preparation method, the use of a readily available and inexpensive nickel catalyst and ligand, can be mild, efficiently realize the halogenating is mixed halo aromatic hydrocarbon or aromatic hydrocarbon can particularly will be cheap and easily obtained but the reaction low activity of the chlorinated aromatic hydrocarbon or aromatic hydrocarbon […] with toxicity is relatively small of the cyano reagent reaction, to prepare the fragrant nitrile or heteroaromatic nitrile compounds. Preparation method of this invention not only has simple operation, moderate, high efficiency and the like, but also has good functional group compatibility and universality and other characteristics of the substrate.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C8H5ClN2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1448-87-9, in my other articles.
