Abstract

Organic condensation reactions involving the elimination of water are effected in the presence of at least one anhydrous, finely powdered calcium salt selected from silicates, aluminates and aluminoferrites, which combine with the water eliminated to give water-insoluble salts during the reaction. Specified salt mixtures are a mixture of calcium aluminate and calcium sulphate which, on hydration gives Candlot's salt (Al2O3, 9CaO, 3Ca SO4, 30H2O) and various hydraulic cements. Reactions effected in examples are esterification, amine formation from an alcohol and ammonia and amide and nitrile formation from a carboxylic acid and ammonia.
