Ammonium chloride is an acidic inorganic compound. It appears as a white, fine crystalline powder that is odourless and highly soluble in water.
Ammonium chloride is manufactured as a by-product from several chemical processes, in particular from the Solvay process (used to produce sodium carbonate). It can also be manufactured directly from the reaction between ammonia and hydrogen chloride or hydrochloric acid.
In nature it found in volcanic regions near fume-releasing vents, where it is referred to as 'sal ammoniac'.
Its main uses are in fertilisers and metalwork. Benco is able to supply treated and untreated tech grades and food grade ammonium chloride.
