摘要： A chemical formulation and method are provided for the treatment of water to prevent, control or inhibit corrosion and/or deposits, particularly for the treatment of water in water distribution piping and equipment and associated heat exchangers and more particularly for the treatment of water in heat transfer equipment wherein water or steam is employed as the heat transfer medium. The method treats the water with at least one mono- or polyhydric alcohol. Optionally, the treatment formulation is a blend of mono- or polyhydric alcohols and further optionally includes one or more of a mixed molecular weight poly(acrylic acid) and/or at least one salt thereof; at least one chromium-free lignosulfonate, and at least one carboxylic acid and/or at least one salt thereof, the carboxylic acid being different from the poly(acrylic acid).
