Abstract
The present invention relates to a kind of method of producing solid-state amyldiacid peroxide, it is to be raw material with hydrogen peroxide, Pyroglutaric acid, water, stir certain hour at a certain temperature, through suction filtration, washing, the dry solid-state amyldiacid peroxide that gets, its content can be up to 98%, and good stability, toxicity are low, have no irritating odor, its dilute aqueous all has good killing action to various bacteriums, bacterial spore, virus, fungi, and thimerosal is also reusable.This solid dosage state amyldiacid peroxide method of producing, its technology is simple, the reaction conditions gentleness, the effective constituent height, construction investment is few, is fit to industrial production.
Description
The present invention relates to a kind of method for preparing sterilizing agent, the preparation method of the solid-state amyldiacid peroxide that particularly a kind of high-content is stable.
As everyone knows, peroxy acid is good oxygenant and sterilizing agent.Lower peroxy acid such as Peracetic Acid can form comparatively stable solution with certain content, but higher volatility and stronger pungent taste are arranged, and this makes its management and use and has all run into difficulty.German patent DE 2654164(the coexist U.S., Japanese publication patent) a kind of method of utilizing Pyroglutaric acid and the synthetic state amyldiacid peroxide liquid dosage form of hydrogen peroxide disclosed, its product content reaches as high as 60%(and calculates with single state amyldiacid peroxide), overcome the shortcoming that Peracetic Acid exists, this sterilizing agent germicidal action is strong, more stable, toxicity is low, non-stimulated flavor, basic non-volatility is a kind of comparatively ideal sterilizing agent.But this sterilizing agent state amyldiacid peroxide content not high (about 50%), and be the aqueous solution, stability is not ideal enough, is not easy to transportation and preservation, influences the widespread use of this sterilizing agent.
The preparation method who the purpose of this invention is to provide a kind of solid-state amyldiacid peroxide, its technology is simple, the reaction conditions gentleness, operation easily, final product active constituent content height, good stability is convenient to transportation and preservation.
The object of the present invention is achieved like this: this method adopts the weight percent of raw material to be respectively hydrogen peroxide 10-50, Pyroglutaric acid 22-48, water 1-66, take by weighing according to quantity and put into reactor and stir, temperature is controlled at 5-30 ℃, and pH value is at 1-12, and the reaction times was at 5-120 minute, carry out conventional suction filtration, washing, drying after the reaction, promptly get the solid-state amyldiacid peroxide finished product.
Because it is promotor that the present invention adopts water, make the hydrogen peroxide oxidation Pyroglutaric acid, so obtain solid-state amyldiacid peroxide unexpectedly, its content (weight percent) is about the 61-98% state amyldiacid peroxide, the 1-50% pentanedioic acid, water 1-10% compares (being water-soluble state amyldiacid peroxide concentrated solution) with prior art, this method need not be added stablizer can obtain the highly stable solid dosage product of performance, this product state amyldiacid peroxide content (calculating with two state amyldiacid peroxides) 61-98%.Suitably control reaction temperature, pH value, time, can improve the yield of product and the content of state amyldiacid peroxide.Therefore, this method compared with prior art, not only technology is simple, raw material is easy to get, low cost of manufacture, and final product active constituent content height, good stability is convenient to transportation and is preserved, and helps wide popularization and application.
The chemical formula C10H14O8 of the solid-state amyldiacid peroxide that makes with this method, molecular weight 262, structural formula HOOC(CH2) 3COOOCO(CH2) 3COOH, outward appearance is white bulky powder, dissolving is very fast in 50 ℃ of warm water, dissolves in the organic solvent such as ethanol basic non-volatility, non-stimulated flavor.Its good stability was at room temperature placed 2.5 years, and state amyldiacid peroxide content rate of descent is about 13-15%.Toxicity test, its mouse oral LD50 are 2483 milligrams/kilogram, are low toxicity material, no cumulative toxicity, no mutagenesis.2% concentration has slight stimulation to the skin nonirritant to mucous membrane.Corrosion test shows that textiles is had fading function, but its quality is not had obvious influence.Chromium plating, nickel plating metal, stainless steel there is not corrosion phenomenon.
Sterilization effect, be the action time that bacterial inactivation rate is reached the state amyldiacid peroxide different concns aqueous solution more than 99.9%: 0.05% concentration was to intestinal bacteria, Staphylococcus albus 2 minutes; To bacterium anthracoides brood cell 1.0% concentration 30 minutes, 0.5% concentration 90 minutes; To Candida albicans 1.0% concentration 120 minutes.Under 20% calf serum protection, to intestinal bacteria and Staphylococcus albus 0.05% concentration 5 minutes; To bacterium anthracoides brood cell 1.0% concentration 30 minutes.1.0% concentration placed for three weeks 25 ℃ of conditions, its density loss to 0.87%, and brood cell's effect is constant substantially extremely.To the HBsAg(hepatitis B surface antigen(HBsAg)) deactivation, 1.0% concentration 5 minutes; Deactivation HBsAg in serum, 1.0% concentration 30 minutes.1.0% concentration is used for nonmetal instrument soaking sterilization can be used 20 days continuously, and HBsAg is still had deactivation.0.5% concentration is used for the tableware soaking disinfection, can use continuously 30 days, still can kill intestinal bacteria and phage F2 thereof.
The minimum inhibitory concentration of state amyldiacid peroxide is: intestinal bacteria 0.031%; Staphylococcus albus 0.016%; Bacterium anthracoides brood cell 0.031%; Candida albicans 0.125%.
The state amyldiacid peroxide mother liquor also has sterilization effect preferably, also can be used for various sterilisation purposes.
Entire reaction course is simple, and no waste produces, and free from environmental pollution, state amyldiacid peroxide solid dosage and mother liquor all can utilize.Raw materials used being easy to get, low cost of manufacture.Wherein raw materials used is that 70-98%, concentration of hydrogen peroxide are that distilled water is advisable for industrial hydrogen peroxide, the water greater than 30% with Pyroglutaric acid content.Its reaction conditions is preferentially selected temperature 8-25 ℃ for use, pH value 2-5, time 40-100 minute.
The invention will be further described below in conjunction with embodiment.
