Abstract:

Sodium chloride is currently used to remove ice from roads. While cheap, sodium chloride is corrosive and contaminates ground water and streams. The Department of Transportation under the aegis of the Federal Highway Administration (FHWA) began a search for a sodium chloride substitute. Calcium magnesium acetate (CMA) has been identified as an excellent candidate de-icing material. The objectives of this project were to examine the best way to prepare dry CMA from CMA solutions and to determine the ice melting ability of CMA. We would then recommend an optimum process for producing solid CMA. Energy & Minerals Research Company (EMR) examined approximately 19 different drying methods for CMA solutions. In addition, we attempted to recrystallize CMA using organic liquids. Several drying methods were finally selected for initial evaluation. Small quantities of CMA were produced, and the product properties were evaluated. Two methods were then selected for further evaluation. Larger quantities were produced and further evaluated. This report contains the data generated during the course of this study and our conclusions based on the data.
