zirconium(+4) cation sulfate tetrahydrate - Uses and synthesis methods
Introduction
zirconium sulfate decomposes ZrO2 above 800 ℃. Zirconium sulfate is soluble in water and sulfuric acid, slightly soluble in ethanol, insoluble in hydrocarbons, and releases a lot of heat when dissolved in water, and the aqueous solution is strongly acidic.
application
zirconium sulfate can be used as a white leather tanning agent to make the leather surface delicate and elastic. it is also used as a raw material for preparing zirconium compounds and can be used as a lubricant, catalyst carrier, etc.
Preparation method
Zirconium sulfate can be obtained by the reaction of zirconium dioxide and sulfuric acid:
ZrO2 2 H2SO4 x H2O → Zr(SO4)2·xH2O
The hydrate obtained is a complex with 7 or 8 coordination of zirconium atom. Water and sulfate are both ligands.
Solubility in water (g/100ml)
Dissolved grams per 100 ml of water:
52.5g/20℃
production method
The eutectic method uses zircon, soda ash, and sulfuric acid as raw materials to prepare zirconium sulfate: the zircon concentrate is crushed and mixed with sodium carbonate in proportion, put into a roasting furnace, and react at 1100~1200 ℃ to generate zirconium Sodium sodium and sodium silicate, the roasted clinker is washed with warm water at 60 ℃, excess alkali is washed, filtered, and the filter cake is dissolved with sulfuric acid at 80~100, then it is prepared by evaporation, concentration or addition of concentrated sulfuric acid, crystallization, filtration and separation, and drying and dehydration at 180 ℃. Its
production method: the metered zirconium tanning agent ZS is added to the acid hydrolysis kettle and decomposed by acid. Centrifugal sharing removes impurities. Put the filtrate into the evaporation pot to concentrate until viscous, and spray dry to obtain the finished product.
