Calcium acetate monohydrate → Calcium Acetate

Participants

Reaction Steps

First, 60 g of hydrated alumina (trade name: Disperal HP14 available from Sasol Ltd.) was added to 800 g of pure water, and 5.28 g of calcium acetate monohydrate (element content of Ca/element content of Al=0.03) was added to the resultant mixture. The resultant dispersoid was dried by a spray-drying method to obtain hydrated alumina 4 which calcium acetate adhered to. The drying temperature (gas phase temperature) was 170° C. The acid site strength of the hydrated alumina 4 was measured by temperature-programmed desorption (TPD) that determines surface activity using ammonia gas. As a result, the presence of acid sites was not confirmed, and it was found that calcium acetate adhered to hydrated alumina.
