Food Grade Ammonium Sulfate Yeast Fermentation Ammonium Sulphate CAS 7783-20-2

 

Description:
Ammonium sulfate is a crystalline powder or granular substance that is colorless or white in appearance. It is highly soluble in water and has a slight ammonia odor. The compound is composed of two ammonium ions (NH4+) and one sulfate ion (SO4^2-).

Specification:
The specifications of Ammonium Sulphate can vary depending on the source and grade. Here are some general specifications:

• Chemical formula: (NH4)2SO4
• Molecular weight: Approximately 132.14 g/mol
• Appearance: Crystalline powder or granules
• Purity: Typically, not less than 99% or higher (depending on the grade)
• Nitrogen content: Typically, around 21% by weight
• Sulfur content: Typically, around 24% by weight
• pH: Usually in the acidic range, around 4.5-6.5

Application:
Ammonium sulfate has various applications in different industries, including:

1. Fertilizer: It is widely used as a nitrogen fertilizer in agriculture due to its high nitrogen content. The availability of both ammonium and sulfate ions makes it suitable for providing essential nutrients to plants. It is particularly beneficial for crops that require a high amount of nitrogen, such as corn, wheat, and rice.

2. Industrial uses: Ammonium sulfate is utilized in several industrial processes, such as the production of fire extinguishing powders, flame retardants, and pharmaceuticals. It is also used as a coagulating agent in the manufacturing of latex products, dyes, and pigments.

3. Food additive: In the food industry, ammonium sulfate is approved as a food additive (E517) and is used as a dough conditioner, yeast nutrient, and stabilizer. It helps improve dough elasticity, texture, and overall baking performance.

4. Laboratory and research: Ammonium sulfate is commonly employed in laboratories for various purposes, including protein purification, DNA precipitation, and as a reagent in chemical reactions.

Features:

1. Nitrogen and sulfur source: Ammonium sulfate provides a readily available source of both nitrogen and sulfur, which are essential macronutrients for plant growth. It supports the development of healthy foliage, promotes protein synthesis, and improves crop yield.

2. pH adjustment: The acidic nature of ammonium sulfate can be beneficial in adjusting soil pH levels, especially for alkaline soils. This can help create a more favorable environment for plant nutrient uptake.

3. Water solubility: Ammonium sulfate has high solubility in water, allowing for easy application through irrigation systems or as a foliar spray. It can be quickly dissolved and absorbed by plant roots.

4. Stability and long shelf life: Ammonium sulfate is relatively stable and has a long shelf life when stored properly. It does not undergo significant degradation or loss of nutrients over time.

5. Cost-effective: Ammonium sulfate is generally cost-effective compared to other nitrogen fertilizers. Its lower cost, combined with its efficacy in supplying nitrogen and sulfur, makes it an attractive option for farmers.

 

Description

 

Ammonium sulfate was the first nitrogenous fertilizer made by the Haber-Bosch process, produced by the reaction of ammonia with sulfuric acid. In contrast with the nitrate salt, it is chemically stable, not highly hygroscopic. It also supplies supplemental sulfur to soils that may be deficient in this element, but this is of minor value when it is used on soils receiving applications of ordinary superphosphate.
The disadvantages of the material are its relatively low nitrogen content, which increases storage and transportation costs, and its marked tendency to cause soil acidification, which is greater than that of any other nitrogen fertilizer material.
