Preparation of calcium trichloroacetate
Alternative Names: TCA-calcium; Calciumtrichloroacetate; TCA-calcium;
Calcium trichloroacetate is prepared by the careful neutralization of the trichloroacetic acid with calcium carbonate. The excess calcium carbonate is filtered and the obtained solution is allowed to evaporate in a large dish. By this method, the air-dried salt crystallizes with three moles of water. In order to obtain the anhydrous salt 50 g of the air-dried calcium trichloroacetate trihydrate are placed in a drying “pistol”, the dryer is charged with phosphorus pentoxide and subjected to a vacuum of a few microns. The drying process last about 80 hours, with several replacements of drying agent. The product is anhydrous when it failed to hydrate the phosphorus pentoxide visibly at 70° C after several hours.
