Background technology
Lithium sulfate, colourless monoclinic crystal or white crystals sprills, water-soluble, be insoluble to acetone and absolute ethyl alcohol, the water solubility 25 DEG C time is 25.7%, has α, β, tri-kinds of crystal formations of γ.α type is white monoclinic crystal, and β type is six reef knot crystalline substances, cube crystallization of γ type.Have hygroscopicity, what gone out by high temperature crystallization in fortified aqueous is very stable without hydration lithium sulfate, has the effect for the treatment of manic-depressive psychosis.
The preparation method of lithium sulfate has two kinds, the one, lithium carbonate method, adds lithium carbonate solution in reactor, under agitation slowly adds sulfuric acid to react, through evaporation and concentration, high temperature crystallization, centrifugation, directly make anhydrous slufuric acid lithium, slightly drying obtains lithium sulfate product.
The 2nd, under constantly stirring, in the suspension of lithium carbonate, slowly add dilute sulfuric acid, to note anti-above because acid adds too fastly, reaction is too fierce and reactant is overflowed.Till reacting and all dissolving to suspension, can make the aqueous solution of lithium sulfate.Evaporation and concentration to 150 DEG C can go out anhydrous slufuric acid lithium from aqueous solution crystallization above.Separate latter 150 DEG C and dry remove a small amount of attached water and can make anhydrous salt product, with traditional sulfuric acid monohydrate lithium that first obtains, and then the method for high temperature dehydration compares, and process is simpler.
Reaction unit is widely used in oil, chemical industry, rubber, agricultural chemicals, dyestuff, medicine, food, has been used for the pressure vessel of the technical process such as sulfuration, nitrated, hydrogenation, hydrocarbonylation, polymerization, condensation.
The preparation of lithium sulfate, reaction is had relatively high expectations, normally under the condition of high temperature and deep-etching, carry out for a long time, therefore the sealing to reaction unit, security, high temperature resistant and corrosion-resistant requirement are very high, and traditional preparation facilities temperature can not reach requirement, complex structure, function singleness, is awkward, because reaction unit is large, when stirring, there is eddy current dead band, cause stirring uneven.
