Abstract

PURPOSE: To effectively prevent the corrosion of metals such as iron contacting with calcium chloride brine by adding one or more kinds of compounds selected from sugar, its analogous compounds and starches to the brine together with an azole compound.
CONSTITUTION: The calcium chloride brine are added one or more kinds of compounds selected from sugar such as glucose, its analogous compounds such as methylose, starch and its hydrolyzates such as low molecular dextrin together with an azole compound such as benzotriazole by small amount. The concn. of the chemicals added is preferably 50W5,000ppm as a whole, and the wt. ratio of the azole compound to the former compounds 1:10W10:1. Thus, only by combining the above- mentioned compounds each having high solubility to the brine and adding them to the brine by a very small amount, superior corrosion preventing property to copper as weell as iron is shown.
