分子式:
CAS号:
性质:又称断链。是链反应中链载体消亡而不再生,从而导致链传播终止的过程。对于以自由基为链载体的链式化学反应来说,可分为体相链终止和复相链终止。在体相链终止中,借助于在单相反应系统中链载体自由基的重结合反应而实现消亡的过程称为重结合链终止,例如2C2H5→C4H10;借助于自由基歧化反应实现消亡的过程称为歧化反应链终止,例如2C2H5→C2H4+C2H6战。此外,体相链终止还可借助链阻化剂(又称链抑制剂)来实现,此称为阻化剂链终止,又称为链阻化或链抑制。复相链终止是气相链反应在低压条件下常见的断链方式,是链载体自由基扩散至器壁并与器壁表面上的自由价结合而实现链载体消亡的过程。
