Mucochloric acid Usage And Synthesis
Chemical Properties
WHITE TO LIGHT BEIGE CRYSTALLINE POWDER
Uses
Mucochloric Acid is an intermediate product of the herbicide Burex that can cause poisioning and skin damage upon exposure. Mucochloric Acid is also a chlorine disinfection byproduct in drinking water with mutagenic activity.
Safety Profile
Poison by ingestion. Moderate skin and severe eye irritant. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl-.
Purification Methods
Crystallise the acid twice from water (charcoal). [Beilstein 3 IV 1720.]
