Description

Ammonium sulfate, commonly known as ammonium sulfate, is an inorganic salt compound with the chemical formula (NH4)2SO4 and a molecular weight of 132.14. It is colorless rhombic crystal at room temperature. Industrial products are generally white or slightly yellow small crystals, but a few by-products are slightly green, dark brown and other colors. The relative density is 1.77, the melting point is 280°C, and it is easily soluble in water. The aqueous solution is acidic, and the solubility in water decreases with the increase of ammonia content. Ammonium sulfate is hygroscopic and solidifies into blocks after absorbing moisture. The chemical properties reflect the characteristics of ammonium salts and sulfates. It reacts with alkali to release ammonia gas, and can be decomposed into ammonia, nitrogen and sulfur dioxide by heating. It reacts with barium chloride to form barium sulfate precipitate, and reacts with alkaline potassium mercuric iodide solution to form brown precipitate.

Main use

In industry: ammonium sulfate is mainly produced by direct reaction of ammonia with sulfuric acid, or by passing ammonia and carbon dioxide into a suspension of gypsum powder. Ammonium sulfate contains about 21% nitrogen and is a quick-acting fertilizer suitable for general crops. Ammonium sulfate can be used in the salting-out process in the pharmaceutical field, yeast culture in fresh yeast production, welding agent, fabric fire retardant, catalyst for food sauce color, dyeing aid for acid dyes, and leather deliming agent, etc.

In agriculture: It is an excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters, and can be used as base fertilizer, topdressing and seed fertilizer. It can react with salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and make refractory materials with boric acid. Adding it to electroplating solution can increase conductivity. It is also a catalyst for food sauce color, a nitrogen source for culturing yeast in fresh yeast production, and an auxiliary dye for acid dyes.

In biology: It is mostly used in protein purification processes because ammonium sulfate is an inert substance and is not easy to react with other biologically active substances. It can protect protein activity to the greatest extent during the purification process. In addition, ammonium sulfate is extremely soluble and can form a high-salt environment, preparing for protein precipitation and subsequent high-salt purification.

Competitive advantage:

1. All granules contain NPK to make the grass color more uniform, no need to mix other fertilizers when using 2. with long-term
effect and high utilization rate, it can greatly reduce the number of fertilization times.
3. Easy to use, do not need a lot of water after fertilization to achieve the desired effect
4. Uniform fertilizer granules, suitable for all kinds of household and agricultural fertilizer application machines
5. The fertilizer prices have strong market competitiveness, can be suitable for domestic use and export abroad.
6. Phosphorus-low formula, less loss and less environmental impact on water sources

Hazard:
Invasion routes: inhalation, ingestion, absorption through the skin.
Health hazards: irritating to eyes, mucous membranes and skin.
Environmental hazards: long-term use will cause soil acidification and hardening.
Explosion hazard: This product is non-flammable and irritating.

Firefighting measures:
Hazardous characteristics: Decomposition by heat produces toxic smoke.
Harmful combustion products: Nitrogen oxides, sulfides.
Firefighting methods: Firefighters must wear full-body fireproof and anti-gas suits and extinguish fires in the upwind direction. When extinguishing a fire, move the container from the fire scene to an open area as much as possible.
