Product details

Ammonium Sulphate

 

Properties:

Formula: (NH4)2SO4

CAS RN:7783-20-2Formula

weight: 132.13

EINECS No.:231-984-1

Element Composition:If pure substance, nitrogen content is 21.21%, sulfer content is 24.26%.

Density:1.769g/cm3

Decomposition temperature:235 degrees centigrade

H.S.code (customs code):31022100

Color:Pure chemicals of ammonium sulfate are colorless rhombic crystals.

Industrial products are white color, light grey or light yellow or yellowish-brown color crystal because of different impurities bearing.

Physicalproperty:easy to dissolve in water and can not dissolve in alcohol, acetone, ammonia;

Appearance: white granular

It is soluble in water and insoluble in alcohol or liquid ammonia. It is prepared commercially by passing ammonia, obtained from destructive distillation of coal, into sulfuric acid.

 

Product description

The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
