岐化作用= 任何化學反應 A + A → A' + A", 而 A, A' and A" 是不同的化合物. 最普遍的岐化作用就是 redox reaction, 氧化還原反應 (此解釋是根據 IUPAC). 另一簡單的解釋為反應中某化合物同時被氧化(oxidize) 及被還原 (reduce)

例如: 2 ArH+ → ArH + ArH2+.
3Cl2 + 6OH− → 5Cl− + ClO3− + 3H2O
2CO → C(s) + CO2

H2O2 + 2H+ + 2e- -> 2H20 (氧化)
H202 -> 02 + 2H+ 2e- (還原)
所以最終 2 H2O2 -> 2H2O & O2

dismutation: A chemical reaction in which a single compound serves both as an oxidizing agent and as a reducing agent.

Disproportionation or dismutation disproportionation is any chemical reaction of the type A + A → A' + A", where A, A' and A" are different chemical species. For example: 2 ArH+ → ArH + ArH2+ The reverse of disproportionation is called comproportionation. This definition comes from IUPAC ([1]) While the most common type is a redox reaction, other types are possible. For example: 2H2O → H3O+ + OH- is also a disproportionation.
