Description
Technical field
The present invention relates to the preparing technical fields of peracid salt, and in particular to potassium hydrogen persulfate composite salts serialization makes
Equipment and preparation method.
Background technology
Potassium hydrogen persulfate composite salts are compound at what is be grouped as by potassium hydrogen peroxymonosulfate, potassium acid sulfate, three kinds of potassium sulfate
Salt is a kind of white particle powder of free-flowing, soluble easily in water, molecular formula 2KHSO5.KHSO4.K2SO4.Permonosulphuric acid
Hydrogen potassium complex salt is a kind of widely used disinfectant, have very strong oxidisability, application field be related to detergent,
Denture cleanser, dry chemicking agent, the anti-shrinking agent of woollen fabrics, the initiator of polymer, printed circuit board micro-etching agent, at waste water
Reason, swimming pool and water body of hot spring disinfection and the refinement etc. of association with pulp bleaching, precious metal.
The method for preparing potassium hydrogen persulfate composite salts at present is chlorosulfonic acid method, anodizing and sulfuric acid process.Chlorosulfonic acid
Method is to react the chlorosulfonic acid quantified with 90% hydrogen peroxide, and controlling reaction temperature reacts and peroxide sulphur is made at -15 DEG C or so
Acid, adds a certain proportion of potassium hydroxide and carries out neutralization and prepare potassium hydrogen persulfate composite salts, which exists the disadvantage is that right
Hydrogen peroxide concentration is more demanding, and reaction temperature is too low, and energy consumption is larger, exists simultaneously byproduct of reaction hydrogen chloride gas, pollution and
Corrosivity is strong, requires production equipment high.Anodizing is to generate peroxy-disulfuric acid with platinum electrode electricity slot electrolysis sulfuric acid, crosses two sulphur
Hydrolysis generates permonosulphuric acid to acid at room temperature.Then it is multiple to can be obtained potassium hydrogen peroxymonosulfate with potassium hydroxide or potassium carbonate neutralization
Close product salt, the shortcomings that technique is the valuable platinum electrolytic cell of anodizing, and equipment investment is big, high energy consumption operate compared with
Complexity, sometimes in the pasty state, hardly possible crystallizes product.Sulfuric acid process reaction step is that the sulfuric acid of high concentration is added drop-wise to the hydrogen peroxide of high concentration
In, and stabilizer is added, temperature control is reacted at 5 DEG C or so, is formed the mixture of peroxosulphuric and sulfuric acid, is added hydrogen
Potassium hydrogen persulfate composite salts are obtained by the reaction in potassium oxide solution.
United States Patent (USP) US5139763 discloses the chemical preparation process of potassium hydrogen persulfate composite salts, and step is by mistake
Peroxosulphuric is made after being reacted in hydrogen oxide and sulfuric acid, adds common potassium compound and acid reaction prepares KHSO5、KHSO4
And K2SO4Mixture, add the mixture to rich in KHSO5Solution in adjust KHSO5/(KHSO4+K2SO4) ratio, make
KHSO in final mixture5/(KHSO4+K2SO) in 1.4-1.6：Between 1, separating mixture forms mud sample, through vacuum tube knot
It is brilliant, dry, obtain product.This method, which needs in addition to prepare, is rich in KHSO5Mother liquor, to improve KHSO5/(KHSO4+K2SO)
Ratio；Potassium hydrogen persulfate composite salts humidity obtained is big, and active o content is low, it is difficult to reach the quality requirement of product.
Chinese invention patent application prospectus CN1528660 discloses a kind of preparation of potassium hydrogen persulfate composite salts
Method, preparation method are that the hydrogen peroxide containing stabilizer is first added into reactor, and sulfuric acid is then added dropwise and is reacted, then
Potassium hydroxide solution is added dropwise, while crystalline form modifying agent is added, through being concentrated in vacuo, crystallisation by cooling dries and potassium hydrogen peroxymonosulfate is made
Compound dried salted products.This method is without preparing in advance rich in KHSO5Mother liquor, stabilizer and crystalline form modifying agent is added and effectively reduces
Monthly average active oxygen loss rate, but there are still addition stabilizers and crystalline form modifying agent to cause product impurity content high, is concentrated in vacuo
It is less efficient.
Chinese invention patent application prospectus CN102311100A discloses a kind of potassium hydrogen persulfate composite salts
Preparation method, preparation method are that the hydrogen peroxide of high concentration and sulfuric acid are first carried out oxidation reaction；Again by K: S than for 0.8-1's
The mixed solution or the mother liquid coming after crystallization centrifuging process of aqueous potassium hydrogen sulfate or potassium acid sulfate and sulfuric acid are added in reaction solution
It is mixed and is reacted, acquisition target product is metastable H2SO5、KHSO5、KHSO4、H2SO4Deng mixed solution；Again will
KOH solution is added in mixed solution is reacted under vacuum, then crystallisation by cooling collects solid using conventional method
Potassium Monopersulfate, it is dry, that is, obtain product, this method need in addition to prepare K: S than for 0.8-1 aqueous potassium hydrogen sulfate or
Potassium acid sulfate is mixed with the mixed solution of sulfuric acid with reaction solution.
Method made above is all batch production substantially, and reaction, dry, packaging are implemented step by step, low production efficiency, product
Unstable quality, the degree of automation is relatively low, exists simultaneously the shortcomings of labor intensity is higher, has to production-scale expansion certain
Inhibit.
