PURPOSE:To provide an anticorrosive capable of stably preventing the corrosion of the steel parts of a soft water boiler by using a mixture of an ascorbate and/or an erythorbate with monosaccharides as an effective component. CONSTITUTION:A water soluble ascorbate and/or a water soluble erythorbate is mixed with monosaccharides such as glucose, mannose and galactose to prepare an anticorrosive for a soft water boiler. The water soluble salt is of an alkali metal base or an org. base. A proper amount of the anticorrosive is added to river water or the like. The anticorrosive forms a corrosion preventing film considered to be a kind of magnetite film on the metal surface of a boiler at the service temp. and pressure of the boiler by the synergistic effect of the components. The film is dense and can protect the metal surface in a corrosive environment at high temp. and pressure.
