OXYGEN ELIMINATOR AND BOILER WATER TREATMENT CHEMICAL PRODUCT.

摘要

The invention describes an oxygen eliminator characterized in that effective component thereof consists of a heterocyclic compound with a N-N union in a ring thereof. An oxygen eliminator characterized in that effective component thereof consists of a heterocyclic compound with a N-substituted amino group. An oxygen eliminator characterized in that effective component thereof consists of a heterocyclic compound represented by following formula: (wherein a, b are integers between 0 and 5 to satisfy relationship "2<- a + b <- 5"). An oxygen eliminator characterized in that effective component thereof consists of azodicarbonamide. An oxygen eliminator characterized in that it includes a heterocyclic compound with N-substituted amino group or salt thereof, and a hydroxybenzene derivative. Those can also contain neutral amine, alkali agent and/or water-soluble polymer.
