Abstract
The invention belongs to the field of chemical preparation technology, and relates to a stabilizing agent for sodium hypochlorite and a usage method thereof. The stabilizing agent for sodium hypochlorite comprises the following components: 5-15wt% of sodium sulfamate, 0.6-1.5wt% of sodium silicate, 1-3wt% of sodium bicarbonate, and the balance being deionized water; the usage method of the stabilizing agent for sodium hypochlorite comprises the following steps: the stabilizing agent for sodium hypochlorite and a 10wt% sodium hypochlorite solution are mixed according to a mass ratio 1:1, after stirring, filtering is carried out. The stabilizing agent ensures that sodium hypochlorite is difficult to decompose in a hot environment, preservation time is substantially prolonged, and preservation time at normal temperature even reaches 12 months or above.
Description
Technical field
The present invention relates to chemicals technical field, particularly to a kind of sodium hypochlorite stabilizer and
Using method.
Background technology
Liquor natrii hypochloritis's self stability is poor, and the actually active phase of presently commercially available liquor natrii hypochloritis is only
It is 3 months, and " sodium hypochlorite class disinfectant solution hygienic quality technical specification " requires that its effect duration reaches
More than 6 months, user can reach 12 months its effect duration more desirable.Both at home and abroad to stability time chlorine
The research and development of acid sodium solution are paid much attention to, it has been disclosed that stable sodium hypochlorite solution formula, preparation side
Method patent and paper nearly hundred.In document, general employing adds sodium phosphate, sodium silicate and surfactant
Improve its stability.Existing stabilizer can improve the stability of liquor natrii hypochloritis to a certain extent,
But the most fundamentally changing the rule of liquor natrii hypochloritis's Auto-decomposition reaction, liquor natrii hypochloritis is difficult to
Reach 6 months effect duration.
The present invention is contemplated to provide a kind of stabilizer to deposit the time limit to improve liquor natrii hypochloritis.
Summary of the invention
A kind of sodium hypochlorite stabilizer of offer and using method thereof are provided.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of sodium hypochlorite stabilizer, bag
Include 5-15wt% sulfamic acid sodium, 0.6-1.5wt% sodium silicate, 1-3wt% sodium bicarbonate and surplus go from
Sub-water.
Concrete, the mass percent of described sulfamic acid sodium is 9.5-10wt%.
Concrete, the mass percent of described sodium silicate is 0.6-0.8wt%.
Concrete, the mass percent of described sodium bicarbonate is 1-2wt%.
The using method of a kind of sodium hypochlorite stabilizer, step is by itself and 10wt% liquor natrii hypochloritis
By 1:1 mass mixing, filter after stirring.
Using technique scheme, technical solution of the present invention provides the benefit that:
1, stabilizer of the present invention can make sodium hypochlorite be difficult to decompose under relatively thermal environment, and the holding time is significantly
Extending, the room temperature holding time even can reach more than 12 months；
2, sulfamic acid sodium can balance the receiving and losing electrons state of sodium hypochlorite, to form the side of micel
Formula effectively suppresses the Auto-decomposition of sodium hypochlorite；
3, sodium silicate can absorb heavy metal ion, and the catalysis of sodium hypochlorite is divided by suppression heavy metal ion
Solve；
4, sodium bicarbonate can regulate the pH of liquor natrii hypochloritis, it is to avoid pH is too low causes sodium hypochlorite to divide
Solve.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
Embodiment 1:
According to sulfamic acid sodium: sodium silicate: sodium bicarbonate: water weight ratio 5:1:1:93 prepares stabilizer,
Then stabilizer is dissolved with the 10wt% liquor natrii hypochloritis waiting weight, obtain the secondary chlorine that concentration is about 5wt%
Acid sodium solution.
Embodiment 2-6:
The method repeating EXPERIMENTAL EXAMPLE 1 by each constituent mass percentage ratio specified in table 1, obtains difference
The liquor natrii hypochloritis of concentration about 5wt%.
Table 1:
The nitrogen-atoms in sulfamic acid sodium in this stabilizer component is+trivalent, is in strong in the solution
Provide electronic state；And the chlorine atom in sodium hypochlorite is+trivalent, it is in strong connecing in the solution
By electronic state, therefore both materials can form more stable micel under covalent effect, enters
And suppress the Auto-decomposition of sodium hypochlorite, it is effectively increased the stability of sodium hypochlorite；Silicon in component
Acid sodium can absorb beavy metal impurity ion, and the catalytic decomposition of sodium hypochlorite is made by suppression heavy metal ion
With, also can improve stability of solution to a certain extent；The pH value of solution can be played by sodium bicarbonate
Stabilize and increase effect, more can delay self decomposing of sodium hypochlorite.
The concrete effect of the present invention is as follows:
To embodiment 1-6 gained liquor natrii hypochloritis sampling and by 5wt% the chlorine without stabilizer treatment
Acid sodium solution, as reference examples, is positioned under 54 DEG C of environment, contains every certain natural law sampling detection effective chlorine
Amount.
Table 2:
By table 2 it will be seen that at relatively high temperatures, through two time-of-weeks, reference examples sodium hypochlorite contains
Amount loss more than 80%, and the content loss of embodiment sodium hypochlorite is less than 20%, serves the most steady
Determine effect.
To embodiment 1-6 gained liquor natrii hypochloritis sampling and by 5wt% the chlorine without stabilizer treatment
Acid sodium solution is as reference examples, and room temperature preservation under the conditions of lucifuge, every certain time sampling detection effective chlorine
Content.
Table 3:
By table 3 it will be seen that under room temperature light protected environment, embodiment 1-6 experiences 12 months times
Sodium chlorate loss only about 2%, and reference examples loss nearly 20%, do not reach that " sodium hypochlorite class disappears
Venom hygienic quality technical specification " requirement, therefore the effect of this stabilizer can make liquor natrii hypochloritis
Use be valid up to more than 12 months, have more market competitiveness.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement,
These broadly fall into protection scope of the present invention.
