calcium oxide in English
The dissociation of calcium carbonate to calcium oxide and carbon dioxide at 25°C and atmospheric pressure provides an example; raising the temperature or lowering the pressure drives the reaction in the forward direction.

A method for the preparation of fatty acid calcium salts, which includes the steps of : (a) providing a fatty acid feedstock having a glyceride content between about 30 and about 60% by weight; (b) adding to the feedstock from about 2 to about 3 equivalents of calcium oxide relative to the feedstock, so that a reactive admixture is formed; and (c) adding to the reactive admixture from about 2 to about 5 equivalents of water relative to the calcium oxide so that the calcium oxide hydrates and neutralizes the fatty acids to form calcium salts.
