The cumulative difference between BDE values of all bonds broken and formed in a chemical reaction thus provides an estimate of the overall reaction enthalpy1. BDE values are thermodynamic quantities but they are also used widely to predict reaction kinetics. For example, BDE values are used to ...

Alkanes are an important part of petroleum, the stability of alkanes under extreme conditions is of great significance to explore the origin of petroleum and the carbon cycle in the deep Earth. Here, we performed Raman and infrared (IR) spectroscopy studies of n-hexane and cyclohexane under high...
The reaction products are subsequently recovered from the fluid medium. Method may be used for polymerisation, e.g. of ethylene, or 12-aminodecane acid in nylon mfr.; or for oxidn. in the liq. phase of low mol. wt. alkanes to alcohols, ketones etc. 展开 ...
