PRODUCTION OF CALCIUM MAGNESIUM ACETATE (CMA) FOR FIELD TRIALS

In Phase II, 200 tons (181.4 tonnes) of calcium magnesium acetate (CMA) were produced by the Bowling Green, KY, plant of RAD Chemicals Division of RAD Services, Inc., under subcontract to SRI International. Most of this material was shipped to selected State Departments of Transportation, for deicing field trials. The rest of the material will be used in other FHWA-sponsored research studies that will evaluate the technical merits and corrosivity of the CMA. The Phase II production used purchased acetic acid and dolomitic lime as raw materials. This was a backup option, selected because the preferred fermentation process studied in Phase I was not yet ready for scale-up. SRI International prepared a complete process description, monitored the production runs, sampled and analyzed the product, and prepared an Interim Manufacturing Guide. (FHWA)
