Importance of heptane
WitrynaBromination is a chemical reaction involving the reaction of a compound, and bromine results in bromine being added to the compound. A saturated compound undergoes bromination via a free radical mechanism. In contrast, unsaturated and aromatic compounds undergo bromination via addition and electrophilic substitution mechanism.

Witryna12 kwi 2024 · A binary two-phase system has two degrees of freedom. At a given T and p, each phase must have a fixed composition. We can calculate the liquid composition by rearranging Eq. 13.2.4: xA = p − p ∗ B p ∗ A − p ∗ B The gas composition is then given by yA = pA p = xAp ∗ A p = ( p − p ∗ B p ∗ A − p ∗ B)p ∗ A p.
