Ammonium bisulfate Chemical Properties, Uses, Production
Chemical Properties
white crystalline powder or chunks. This compound is one of several salts that can form from the reaction of ammonia and sulfur bearing gases, most particularly sulfur trioxide. This product is frequently found in the overhead of crude distillation units and can be quite corrosive to steel equipment. Chemical corrosion inhibitors are often used to control corrosion from ammonium bisulfate.
Uses
In hair-waving preparations; as catalyst for organic reactions.
Uses
Ammonium hydrogen sulfate is used as pharmaceutical intermediates and chemical reagents.
Preparation
Ammonium bisulfate is prepared by reacting sulfuric acid with ammonia.
General Description
Ammonium hydrogen sulfate is a colorless to white, powdered solid. Ammonium hydrogen sulfate is toxic by ingestion. When heated to high temperatures, Ammonium hydrogen sulfate may release toxic sulfur oxide and nitrogen oxide fumes. Ammonium hydrogen sulfate is soluble in water. Ammonium hydrogen sulfate is a chemical catalyst, used in hair preparations.
Air & Water Reactions
Ammonium hydrogen sulfate dissolves in water with the evolution of some heat and hydrolyzes to form some amounts of sulfuric acid. Deliquescent.
Reactivity Profile
Acidic salts, such as Ammonium hydrogen sulfate, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Safety Profile
Moderately toxic by ingestion. A corrosive. See also SULFATES. Dangerous; when heated to decomposition it emits highly toxic fumes of sulfuric acid and SO,, NH3, and NOx,.
Purification Methods
It crystallises from water at room temperature (1mL/g) on adding EtOH and cooling. (NH4) HSO4 is formed as deliquescent rhombic crystals on cooling a solution of (NH4)2SO4 in hot conc H2SO4 but EtOH decomposes it to (NH4)3H(SO4)2 [Dunnicliff J Chem Soc 123 476 1923]. When powdered (NH4)2SO4 is heated below 100o, it loses NH3, and at 300o it is completely converted to fused (NH4) HSO4, m 140o, but >300o it decomposes to SO2 and N2 [Smith J Chem Soc 30 253 1911].
