Application of 108-47-4, In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 108-47-4, Name is 2,4-Dimethylpyridine, molecular formula is C7H9N.

Group-contribution based estimation of pure component properties
A new method for the estimation of properties of pure organic compounds is presented. Estimation is performed at three levels. The primary level uses contributions from simple groups that allow describing a wide variety of organic compounds, while the higher levels involve polyfunctional and structural groups that provide more information about molecular fragments whose description through first-order groups is not possible. The presented method allows estimations of the following properties: normal boiling point, critical temperature, critical pressure, critical volume, standard enthalpy of formation, standard enthalpy of vaporization, standard Gibbs energy, normal melting point and standard enthalpy of fusion. The group-contribution tables have been developed from regression using a data set of more than 2000 compounds ranging from C = 3-60, including large and complex polycyclic compounds. Compared to the currently used group-contribution methods, the new method makes significant improvements both in accuracy and applicability.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, they are the focus of active research. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 108-47-4
