Iron(ii) chloride tetrahydrate description
Iron 2 chloride tetrahydrate is green crystal with hygroscopicity and a relative density of 1.93. Very soluble in water and ethanol, soluble in acetone, slightly soluble in benzene, insoluble in ether. Easily oxidized in humid air. Production method: Heat iron in a dry hydrogen chloride stream at a temperature controlled below 500°C, or reduce anhydrous ferric chloride with dry hydrogen at 300-350°C.
The application of ferrous chloride tetrahydrate:
1. Used for sewage and wastewater treatment. Ferrous chloride tetrahydrate has a unique decolorization ability and is suitable for the sewage treatment of dye intermediates, printing and dyeing, and papermaking industries. It can simplify the water treatment process, shorten the water treatment cycle, and reduce the cost of water treatment; it has apparent treatment effects on various types of sewage, electroplating, leather, and papermaking wastewater, and the removal rate of different heavy metal ions in wastewater and sewage is close to 100%. With low cost, it is an ideal agent for sewage treatment.
2. As a reducing agent and mordant, it is widely used in textile and dyeing, pigment and dyeing, manufacturing, and other industries.
3. Ultra-high pressure lubricating oil components
4. Medicine, metallurgy, and photography.
5. Production of ferric chloride. Ferrous chloride tetrahydrate solid ,hydrochloric acid, and chlorine gas are the primary raw materials used to produce ferric chloride.
6. Production of solid polyferric chloride.
7. Production of erasable ink.
8. Used as an analytical reagent.
9. Unleaded gasoline additives, etc
