The present inventors have made a gel composition for releasing chlorine dioxide which can keep the chlorine dioxide release rate constant at a predetermined temperature and for a long time in a stable state for a long time, Thereby completing the invention.
Hereinafter, the present invention will be described in detail.
Chlorine dioxide For standing release Gel type Composition
The present invention relates to chlorite; a buffer solution to maintain a pH of 1.5 to 4.5; And a gelling agent for releasing chlorine dioxide from the chlorine containing gelling agent.
Specifically, the gel composition for releasing chlorine dioxide according to the present invention comprises chlorite; a buffer solution to maintain a pH of 1.5 to 4.5; And a gelling agent, such as chlorite; a buffer solution to maintain a pH of 1.5 to 4.5; And gelling agents are all used as reactants for producing and releasing chlorine dioxide in a stable state (gel form).
Conventionally, various methods such as reaction of chlorous acid and acid, reaction of chlorite and chlorine, reaction of hypochlorite and acid have been known as methods for producing chlorine dioxide.
In the present invention, the reaction of chlorite and acid was used to produce stable chlorine dioxide in a stable state, and optimal conditions for this were derived.
That is, the reaction of chlorite and acid to produce chlorine dioxide constantly is performed by the following two-step reaction, in which the reversible reaction takes place in the one-step reaction and the irreversible reaction occurs in the two-step reaction .
(Step 1) ClO 2 - + H + ↔ HClO 2
(Step 2) 5HClO 2 ? 4ClO 2 + HCl + 2H 2 O
According to the above two-step reaction, the production process of chloric acid through the reaction of chlorite and acid is balanced (Step 1), and chlorine dioxide is produced by decomposition of generated chloric acid (Step 2) Due to the depletion of chloric acid by the first step, chlorine is continuously produced to maintain equilibrium.
The chlorites are used as a starting material for the first step reaction, and sodium chlorite or calcium chlorite may be used as the chlorite.
The buffer solution for maintaining the pH of 1.5 to 4.5 is also used as an acid which is the starting material of the first step reaction, which determines the first step reaction rate. The buffer solution is intended to maintain the pH of the composition at 1.5 to 4.5.
That is, the buffer solution is not used for stabilization of chlorine dioxide itself but is used as a reaction material for producing chlorine dioxide as a product.
In particular, when the pH of the composition is maintained at 2.5 to 3.5, the chlorine dioxide can be controlled at an optimum reaction rate for producing chloric acid. Thus, the chlorine dioxide release rate (0.1 mg / day to 5.0 mg / day) can be kept constant.
For example, when the pH of the composition is maintained at 2.3 to 3.2, 6 to 31% of the chlorites produce chlorous acid, and 31% of the chlorites at pH 2.3, 10% of the chlorites at pH 2.9, 6% of the total chlorine is produced.
Specifically, the buffer solution may contain at least one acid selected from the group consisting of formic acid, acetic acid, maleic acid, citric acid, hydrogen sulfate, phosphoric acid, and lactic acid; Or an acid and a salt thereof and a solvent.
At this time, the acid may be diluted with the solvent at a weight ratio of 200 to 300 times and used as a buffer solution.
Specifically, the buffer solution may contain at least one acid selected from the group consisting of formic acid, acetic acid, maleic acid, citric acid, hydrogen peroxide, phosphoric acid and lactic acid, or may be a mixture of the acid and its salt.
Particularly, when the acid and its salt are mixed with the buffer solution, the time for releasing chlorine dioxide at a constant rate can be further increased.
The weight ratio of the chlorite and the acid is preferably 1: 1 to 1:10, more preferably 1: 3 to 1: 5, but is not limited thereto. At this time, if the weight ratio of chlorite and acid is less than the above range, there is a problem that the total amount of chlorine dioxide is reduced. If the weight ratio of chlorite and acid exceeds the above range, the reaction rate for producing chlorine dioxide becomes too fast There is a problem that the emission time is reduced.
In particular, the gelling agent plays an important role in controlling the initial release rate of chlorine dioxide by controlling the number of collisions between the reactants. The gelling agent acts to control the initial release rate of chlorine dioxide by controlling the viscosity of the composition to stabilize the chlorine dioxide. Specifically, carboxymethylcellulose or guar gum may be used as the gelling agent.
The weight ratio of the chlorite and the gelling agent is preferably 1: 1 to 1:10, more preferably 2: 3 to 1:10, but is not limited thereto. If the weight ratio of the chlorite and the gelling agent is more than the above range, the viscosity of the composition becomes too high, the amount of chlorine dioxide is reduced due to a decrease in the number of collisions between the reaction materials, and the release time is too short , Chlorite and gelling agent is less than the above range, there is the opposite problem.
The viscosity of the composition may be from 1,000 cps to 10,000 cps at 25 ° C and preferably from 3,000 cps to 10,000 cps, but is not limited thereto. When the viscosity of the composition is less than the above range at 25 캜, the reactivity in the composition is increased and the initial release is too fast. When the viscosity of the composition exceeds 25 캜, There is a problem that the emission amount becomes too low.
Chlorine dioxide For standing release Pack and a method for manufacturing the same
Further, the present invention relates to the above-described chlorine dioxide release gel-type composition; And the oxygen transmission rate for sealing the composition provides a 1,000cc / m 2 / day to 50,000cc / m 2 / day of a film pack for release of chlorine dioxide comprising a stand.
According to the pack for discharging chlorine dioxide according to the present invention, chlorine dioxide is produced in the gelatinous state in the sealed film and chlorine dioxide is released to the outside of the sealed film. Therefore, a device for separately producing chlorine dioxide is not required.
The pack for chlorine dioxide desorbing according to the present invention comprises a chlorine dioxide desorbing gel composition and a film, as described above for the composition.
In addition, the film must be sealed to the composition, wherein the oxygen transmission rate 1,000cc / m 2 / day to 50,000cc / m in 2 / day. Preferably by an oxygen permeability 5,000cc / m 2 / day to 50,000cc / m 2 / day, more preferably, the oxygen transmission rate maintaining the 5,000cc / m 2 / day to 10,000cc / m 2 / day, dioxide The chlorine release rate can be controlled and maintained constant.
The film may also comprise a biaxially oriented polypropylene layer and a cast polypropylene layer. At this time, the biaxially stretched polypropylene layer corresponds to the outer layer on the side facing the outside (air or water), and the cast polypropylene layer corresponds to the inner layer on the side contacting the composition. The biaxially stretched polypropylene is a polypropylene film made by stretching in the transverse direction and the longitudinal direction when the resin is melted, compressed and compressed in a mold frame, and is characterized by excellent strength, heat shrinkability and transparency. From the viewpoint of mechanical strength. In addition, the cast polypropylene layer is a polypropylene film made of resin, which is formed by melting, compressing, and compression-molding in a mold, and is excellent in thermal adhesiveness, and preferably has a thickness of 10 to 50 탆.
The pack preferably maintains a release rate of chlorine dioxide of from 0.1 mg / day to 5.0 mg / day at 5 ° C. for 30 days or more, and the pack has a concentration of 0.1 mg / day to 5.0 mg / The chlorine release rate is preferably maintained, but not limited thereto.
That is, the pack can maintain a chlorine dioxide release rate at a constant rate for a relatively long period of time at room temperature not lower than the boiling point of chlorine dioxide, which is advantageous for storage of agricultural and marine products and prevention of degeneration by bacteria during distribution of agricultural and marine products.
