Potassium sulfate Chemical Properties,Uses,Production

Description

Potassium sulfate (K2SO4) is a kind of chemical compounds that is commonly used in agriculture. The dominant application of potassium sulfate is as a fertilizer, which is commonly applied to offer both potassium and sulfur, thus improving the quality and yield of crops growing in soils that lack an adequate supply of this essential elements. Besides, the crude potassium sulfate is sometimes employed in the production of glass. It also has applications in other industries, which is used as a flash reducer in artillery propellant charges and as an alternative blast media similar to soda in the process of soda blasting.

Chemical Properties

Potassium sulfate,K2804, also known as salt of Lemery and arcanite, is a colorless crystalline solid that melts at 1072°C(1960 OF). It is soluble in water,but insoluble in alcohol. Potassium sulfate is used in manufacturing glass, aluminum, fertilizers, and in medicine.

Uses

Technical grades are used in fertilizers for manufacture of potassium alum, potassium carbonate and glass; the reagent grade is used in the Kjeldahl determination of nitrogen.

Uses

potassium sulfate is a reagent in cosmetics. Potassium sulfate is an inorganic salt with a primary function as a viscosity-increasing agent.

Uses

Potassium Sulfate is a flavoring agent that occurs naturally, consisting of colorless or white crystals or crystalline powder having a bitter, saline taste. it is prepared by the neutralization of sulfuric acid with potassium hydroxide or potassium carbonate.

Definition

A white crystallinepowder, K2SO4, soluble inwater and insoluble in ethanol;rhombic or hexagonal; r.d. 2.66; m.p.1069°C. It occurs naturally assch?nite (Strassfurt deposits) and inlake brines, from which it is separatedby fractional crystallization. Ithas also been produced by the Hargreavesprocess, which involves theoxidation of potassium chloride withsulphuric acid. In the laboratory itmay be obtained by the reaction ofeither potassium hydroxide or potassiumcarbonate with sulphuric acid.Potassium sulphate is used in cements,in glass manufacture, as afood additive, and as a fertilizer(source of K+) for chloride-sensitiveplants, such as tobacco and citrus.

Safety Profile

Moderately toxic to humans by ingestion. Moderately toxic experimentally by subcutaneous route. Swallowing large doses causes severe gastrointestinal tract effects. When heated to decomposition it emits toxic fumes of K2O and SOx. See also SULFATES.

Purification Methods

Potassium sulfate [7778-80-5] M 174.3, m 1069o, d 4 2.67 It crystallised from distilled water (4mL/g at 20o; 8mL/g at 100o) between 100o and 0o.
