Abstract
The present invention provides a technology for producing tetrahydrated zirconium sulfate using salt or alkali compounds of zirconium and sulfuric acid as raw materials. The present invention particularly comprises: salt or alkali compounds of zirconium are mixed with water and sulfuric acid according to a certain proportion; through sufficiently stirring and grinding, the mixture of the previous raw materials react completely; then, the raw materials are dissolved, filtered and crystallized to produced tetrahydrated zirconium sulfate. The method that the salt or alkali compounds of the zirconium are directly mixed to react with the sulfuric acid is used by the technology of the present invention, which has the characteristics of simple equipment, short technological process, high yield and no three-waste discharge. Thus, the technology for producing tetrahydrated zirconium sulfate using salt or alkali compounds of zirconium and sulfuric acid as raw materials can be used for processing zirconium compounds recovered in the processes of producing high purity tetrahydrated zirconium sulfate and zirconium series chemical products.
Description
Technical field
The invention provides with the salt of zirconium or bases compound, sulfuric acid is raw material, produces the production technique of tetrahydrated zirconium sulfate, belongs to technical field of inorganic chemical industry.
Background technology
Traditional production process of tetrahydrated zirconium sulfate, be raw material normally, form complex process through operations such as oversintering, washing, sulfuric acid acidation, crystallizations with zircon sand etc., and the iron owing to containing usually in the zircon sand about 2% is difficult to produce the higher tetrahydrated zirconium sulfate of purity in order to last method.
Summary of the invention
The purpose of this invention is to provide a kind of economical and effective and must produce the method for tetrahydrated zirconium sulfate, but shortened process, cut down the consumption of energy, spent acid is easy to handle, be easy to reclaim byproduct, eliminate environmental pollution, the processing that can be used for production high purity tetrahydrated zirconium sulfate and produce the zirconium compounds that reclaims in the zirconium series chemical product process.
The object of the present invention is achieved like this:
1. salt or the bases compound with zirconium mixes by a certain percentage with water.2. a certain amount of sulfuric acid is added in the mixture under stirring, grinding state, heating in case of necessity makes it abundant reaction, and drying is pulverized, and promptly generates tetrahydrated zirconium sulfate.When 3. needing further to make with extra care, add a certain amount of pure water and form solution, solution is removed by filter impurity.4. a certain amount of sulfuric acid is added in the filtrate under whipped state, make it sufficient crystallising.5. reactant is carried out centrifugally, solid-liquid separation promptly obtains purer tetrahydrated zirconium sulfate; Mother liquor can be reused after concentrating or sale is used to produce vitriol etc. as byproduct.
The production technique of production tetrahydrated zirconium sulfate of the present invention, the salt of zirconium or bases compound comprise normal salt such as zirconium oxychloride, zirconyl carbonate, zirconium basic sulphate, zirconium hydroxide, double salt, subsalt, oxyhydroxide etc.
A kind of production technique of producing tetrahydrated zirconium sulfate of the present invention, the salt of zirconium or bases compound and water, vitriolic ratio are different and different by above raw material, step 1. 2. in three's optimum proportion be that gram-equivalent number equates that reaction generates tetrahydrated zirconium sulfate.

Embodiment 3
1. will place the acid corrosion-resistant container in the zirconium hydroxide that zirconium dioxide contains zirconium amount about 35%.2. by water: the part by weight of zirconium hydroxide=0.5 adds pure water in container, and stirs.3. press sulfuric acid: the part by weight of zirconium hydroxide=0.61 adds the vitriol oil of sulfuric acid content more than 98% in container, and 4. by water: the part by weight of zirconium hydroxide=0.55 adds pure water in container, and stirs, and crystallization is fully dissolved.5. solution is removed by filter insoluble impurities.6. the solution after will filtering places the acid corrosion-resistant container, under whipped state, presses solution then: the volume ratio of sulfuric acid=2 adds the vitriol oil of sulfuric acid content more than 98% in container, make the zirconium sulfate sufficient crystallising.7. after the crystal solution temperature being reduced to room temperature, put into the whizzer centrifugal solid-liquid and separate, solid part is a tetrahydrated zirconium sulfate, and liquid portion is a dilute sulphuric acid, applies mechanically after concentrating.
Embodiment 4
1. will place the acid corrosion-resistant container in the zirconium hydroxide that zirconium dioxide contains zirconium amount about 35%.2. press sulfuric acid: the part by weight of zirconium hydroxide=0.61 adds the vitriol oil of sulfuric acid content more than 98% in container, 3. stir, grind, and makes it abundant reaction.4. drying is removed attached water, is tetrahydrated zirconium sulfate.
