Oxygen scavenger and boiler water treatment chemical

本发明提供若干种氧气净化剂以及含有该净化剂的锅炉水处理剂。各氧气净化剂中分别含有下述有效成分，其环上具有N-取代氨基基团的杂环化合物或其水溶性盐；含式(A)表示的杂环化合物；含式(B)表示的杂环化合物；含偶氮二酰胺；包括具有N-取代氨基基团的杂环化合物或其盐和羟基苯衍生物。它们可以进一步含有中性胺，碱性试剂和/或水溶性聚合物，以形成锅炉水处理化学制剂。 An oxygen scavenger characterized in that the effective component thereof consists of a heterocyclic compound with N-N bond in a ring thereof. An oxygen scavenger characterized in that the effective component thereof consists of a heterocyclic compound with N-substituted amino group. An oxygen scavenger characterized in that the effective component thereof consists of a heterocyclic compound represented by the following formula: (wherein a, b are integers between 0 and 5 to satisfy a relation "2 ≤ a + b ≤ 5"), An oxygen scavenger characterized in that the effective component thereof consists of azodicarbonamide. An oxygen scavenger characterized by including a heterocyclic compound with N-substituted amino group, or the salt thereof, and a hydroxybenzene derivative. Those may contain further neutral amine, alkalic agent and/or water soluble polymer.
