(Thio)Carboxylic Acid Salts - Alfa Aesar

Pyrolysis of calcium salts is a route to the preparation of ketones. The ammonium salt of carboxylic acid is used in the preparation of carboxamides. Industrially, sodium or potassium salts of long chain fatty acids are used in the manufacture of the anionic surfactant soap.

Thiocarboxylic acid salts or thiocarboxylate salts are organic compounds that have -C(=O)S- anionic group in them.

Calcium oxide - Wikipedia

Preparation Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln.This is accomplished by heating the material to above 825 C (1,517 F), a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO 2), leaving quicklime.
