The present invention provides a kind of preparation method of disinfectant, including seawater is added into sodium hydroxide, filters, addition sodium hydroxide, filtering precipitation, adds hydrochloric acid, heating evaporation concentration, crystallisation by cooling, dries and obtain finished product.This method is simple and practical, and manufacturing cost is low, suitable for producing the product in enormous quantities.
Description
Technical field
The invention belongs to chemical field, more particularly to a kind of preparation method of disinfectant.
Background technology
The level that disinfectant acts on according to it can be divided into bactericidal agent, high effect disinfectants, middle effect disinfectants, low effect disinfectants.
Bactericidal agent can kill all microorganisms and reach sterilizing requirement, including formaldehyde, glutaraldehyde, oxirane, Peracetic acid, peroxide
Change hydrogen, chlorine dioxide, chlorine, copper sulphate, quick lime, ethanol, etc..High effect disinfectants can kill all bacterial propagules（Including
Mycobacteria）, virus, fungi and its spore etc., also have certain killing effect to bacterial spore, reach high level disinfection requirement,
Including chlorine-containing disinfectant, ozone, methyl hydantoin class compound, double-chain quaternary ammonium salt etc..Middle effect disinfectants can only kill branch
The microorganisms such as bacillus, fungi, virus and bacterial propagule, reach sterilization and require, including iodine-containing disinfectant, alcohol disinfectant, phenol
Class disinfectant etc..Low effect disinfectants can only kill bacterial propagule and close nma virus, reach disinfectant requirement, including benzalkonium bromide
Deng quaternary ammonium disinfectant, Chlorhexidine（Chlorohexidene）Deng biguanides disinfectant, the metal ion class disinfectant such as mercury, silver, copper and in
Herbal medicine disinfectant.
The content of the invention
In order to overcome above mentioned problem, the present invention provides a kind of preparation method of disinfectant, including seawater is added into hydroxide
Sodium, filtering, sodium hydroxide is added, filtering precipitates, addition hydrochloric acid, heating evaporation concentration, crystallisation by cooling, and drying obtains finished product.
Preferably, in a kind of preparation method of disinfectant, add after 3moL/L sodium hydroxide solution be stirred until
The pH value of solution is 9.6, and the magnesium ion that now we need does not separate out, and is filtered to remove metal ion and mud most in seawater
Sand, filter residue is washed the magnesium ion on filter residue is drawn onto in filtrate.
Preferably, in a kind of preparation method of disinfectant, 3moL/L sodium hydroxide is continuously added toward the filtrate after filtering
Solution is simultaneously constantly stirred the pH value magnesium ion precipitation untill the pH value of solution is 11.6, now allowed completely.
Preferably, in a kind of preparation method of disinfectant, the mixture that PH is 11.6 is filtered and washs precipitation, discards filter
Liquid and cleaning solution, filter residue are stand-by.
Preferably, in a kind of preparation method of disinfectant, the filter residue that will filter gained adds 3moL/L hydrochloric acid and continuous
It is stirred until there is no precipitation in solution.
Further, in a kind of preparation method of disinfectant, by add hydrochloric acid after solution be placed in ventilation continue plus
Thermal evaporation concentration stops heating until solution is left half or so, and crystallisation by cooling is carried out in ventilation.
Preferably, in a kind of preparation method of disinfectant, crystal is placed in by gained crystal with after ethanol wash 2 to 3 times
Small fire drying, obtains product in ventilating kitchen.
The present invention provides a kind of preparation method of disinfectant, including seawater is added into sodium hydroxide, filters, and adds hydroxide
Sodium, filtering precipitation, hydrochloric acid is added, heating evaporation concentration, crystallisation by cooling, dries and obtains finished product.This method is simple and practical, obtains
Product purity is high.
Accompanying drawing 1 is a kind of specific steps of the preparation method of disinfectant.
Brief description of the drawings
The step of accompanying drawing 1 is a kind of preparation method of disinfectant of embodiment 1 is schemed.
Embodiment
With reference to case study on implementation, the present invention is described further.
Case study on implementation 1
Reference picture 1, a kind of preparation method of disinfectant of the present invention comprise the following steps：
1st, the insoluble matter in solution and most metal ion are removed：
20mL seawater is taken in large beaker, 3moL/L sodium hydroxide solution is added and the pH value of measurement solution is counted with PH, until
The pH value of solution is that 9.6 stoppings add sodium hydroxide solution, is sufficiently stirred solution and is filtered, filter residue distillation water washing,
It is stand-by that cleaning solution pours filtrate into.
2nd, magnesium hydrate precipitate is prepared：
Filtrate obtained by step 1 is continuously added into sodium hydroxide solution and counts the pH value of measurement solution with PH until the PH of solution reaches
Untill 11.6, filtered after being sufficiently stirred solution, and with water washing filter residue is distilled 2 times, discard filtrate and cleaning solution, filter residue
It is stand-by.
The ionic equation of reaction is：Mg2++2OH-=Mg（OH）2↓
3rd, disinfectant magnesium chloride is prepared：
If step 2 gained filter residue, which is added in 3moL/L hydrochloric acid solution, to also have precipitates undissolved, it can add 5 in right amount ~
10mL hydrochloric acid carry out it is molten third constantly be stirred until solution weight precipitation be completely dissolved, add the process of hydrochloric acid solution need into
Row is stirred continuously, and resulting solution is placed on into heating evaporation in ventilating kitchen after reaction completely concentrates, and it is obvious to treat that solution surface occurs
Stop heating during epitaxial, solution continues to be placed on the crystallisation by cooling in ventilating kitchen, then by gained crystal ethanol wash 2 times, puts
With small fire drying in ventilating kitchen, product is obtained.
Reaction equation is：Mg（OH）2+2HCl=MgCl2+2H2O
The present invention provides a kind of preparation method of disinfectant, including seawater is added into sodium hydroxide, filters, and adds sodium hydroxide,
Filtering precipitation, hydrochloric acid is added, heating evaporation concentration, crystallisation by cooling, dries and obtains finished product.This method is simple and practical, and cost is low, obtains
The product purity arrived is high.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
Utilization, it can be applied to various suitable the field of the invention completely, can be easy for those skilled in the art
Other modification is realized on ground, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not
It is limited to specific details and shown here as the case study on implementation with description.
