Possible applications of ammonium hydrogensulfite (NH4) HSO3 (10192-30-0)
Ammonium hydrogensulfite has a particularly large efficacy spectrum and can be implemented accurately in production
processes of different branches of industry. TIB® Thio ABS can be manufactured individually and according to specifications for the respective production steps - concentrations and purity levels can be determined in a tailor-made manner. Ammonium hydrogen sulfite is used regularly in wine production. The aim here is to promote parallel yeast formation. This is made possible by a broadened field of action in sulfurization, in which ammonium hydrogen sulfite as the SO2 formulation represents the core. Compared to gaseous SO2, there are clear advantages in terms of safety and dosing.
Ammonium hydrogen sulfite has been legally approved for use to promote yeast formation and yeast nutrition. In particular, the proportion of yeast is increased, which can be utilized by nitrogen. Depending on the area of application, legally defined quantities of maximum dosage can be obtained. Furthermore, the authorization does not cover the use in the production of eco-wines. TIB® Thio ABS can, however, be used on grapes, mash, must, partly fermented grapes and young wine.
The use of TIB® Thio ABS is not without a reason primarily forced in wine production because it is in ready-to-use quality. This facilitates application, makes the stabilizing agent very safe and effective due to the use option by means of metering pumps. TIB® Thio ABS is an absolutely practical alternative to conventional SO2 addition using gas or potassium disulfite.
Further applications of ammonium hydrogensulfite (NH4) HSO3 (10192-30-0) in industrial production
Ammonium hydrogen sulfite from TIB Chemicals makes a valuable contribution to the increase of occupational safety in the company. This is mainly due to the lack of the need of dilution because the product is available as a ready-for-use solution. It can be easily implemented in existing production scenarios, since it allows an absolutely accurate dosage and is therefore cost-neutral compared to a gaseous admixture. In addition, there is no longer any odor in the course of the application.
TIB® Thio ABS is characterized by a long durability, so that the product can be stored even during periods of reduced production. For example, it can be used as an ideally dosed reductant in the chemical and pharmaceutical industry. Further uses of ammonium hydrogen sulfite are e.g.
- - Use as oxygen scavengers in the field of oil extraction or in seawater desalination plants
- - Use as a bleaching agent in the production of paper and cellulose
- - Use as a formaldehyde trap in the wood processing industry
- - Exactly dosageable reducing agent for keratin
- - Disruptants in the production of fibers
- - Fast fixation solvents in photochemistry
Concluding remarks on the use of ammonium hydrogensulfite (NH4) HSO3 (10192-30-0)
Ammonium hydrogensulfite combines advantages of an SO2 administration with the advantages of a precise dosage and high profitability. Not without reason, it is one of the essential aids in the production of caramel for food and beverages. However, it is also used as a preservative in the production of cosmetics. TIB® Thio ABS is the medium of choice in the segment of sulfurization with liquid formulations.

General Description
Ammonium bisulfite is colorless crystals which are soluble in water. It is noncombustible. It is corrosive to aluminum. It is a strong irritant to skin and mucous membranes. It is toxic by skin absorption.
Reactivity Alerts
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: None (USCG, 1999)
Health Hazard
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:
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 environmental contamination. (ERG, 2020)
Reactivity Profile
Inorganic reducing agents, such as AMMONIUM BISULFITE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. Their reactions with oxidizing agents may be violent. Sulfites and hydrosulfites (dithionites) can react explosively with strong oxidizing agents. Sulfites generate gaseous sulfur dioxide in contact with oxidizing acids and nonoxidizing acids.

Isolation and Evacuation
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)
Non-Fire Response
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2020)
