Abstract
Several novel means are presented of chemically combining calcium/magnesium acetate with calcium chloride to form a series of calcium magnesium acetate-chloride triple-salts. The low-cost processes are carried out using minimal proportions of water, and no co-products or by-products are formed. Products are optionally pelletized for use as roadway deicing agents. By adjusting the relative amount of chloride input, products can be tailored to adequately perform a given deicing or freezing-point depression task with a minimum of environmental pollution by chloride. All product variations are non-deliquescent. In the preferred embodiment, lime is reacted with concentrated acetic acid to form calcium/magnesium acetate. To the acetate is added an aqueous calcium chloride solution. The concentration of water in the reaction batch is critical to the attainment of complete chemical combination to form a flowable solid product.
