Read： 561 Time：17months ago Source：Transform the World with Simplicity

Ammonium sulfate is an important raw material for chemical production, which has a wide range of properties and uses. This article will introduce in detail the properties, production methods, quality indicators and applications of ammonium sulfate in different fields.

1. the nature of ammonium sulfate

ammonium sulfate is a colorless crystal or white particles, with strong hygroscopicity. It is easily soluble in water, caking after moisture absorption, and is not easy to break. Ammonium sulfate is rich in nitrogen and has high fertilizer efficiency. In addition, it also has the characteristics of neutral pH and not easy to absorb moisture and agglomerate. Method for Producing Ammonium Sulfate

2. Ammonium sulfate

can be produced by a neutralization reaction between synthetic ammonia and sulfuric acid. In the production process, it is necessary to control the reaction temperature, pH value, crystallization conditions and other factors to ensure product quality.

3. the quality index of ammonium sulfate

the quality index of ammonium sulfate mainly includes nitrogen content, moisture, free acid, water insoluble matter and so on. Among them, the nitrogen content is an important indicator to measure the quality of ammonium sulfate, which is generally required to be above 21%.

4. the use of ammonium sulfate

1. fertilizer: ammonium sulfate as a commonly used nitrogen fertilizer, suitable for a variety of soil and crops. It can improve the fertility of the soil, promote the growth of crops, and improve the yield and quality of crops.
2. Feed additives: Ammonium sulfate is rich in nitrogen and can be used as an additive for animal feed to promote animal growth and development.
3. industrial raw materials: ammonium sulfate can be used to produce other chemicals, such as sulfuric acid, nitric acid, urea and so on. In addition, it can also be used as raw materials for printing and dyeing, pharmaceuticals, plastics and other industries.

5. the storage and transportation
of ammonium sulfate
ammonium sulfate should be stored in a dry, cool, well-ventilated place, avoid direct sunlight and high temperature. During transportation, moisture and damage should be prevented to avoid affecting product quality.

In conclusion, ammonium sulfate, as an important raw material for chemical production, has a wide range of properties and uses. In the production process, product quality needs to be strictly controlled to ensure its application effect in different fields. At the same time, it is also necessary to pay attention to keeping the product dry and intact during storage and transportation to avoid affecting its properties and application effects.
