Description
One, technical field
What the present invention relates to is disinfectant for animals, specifically be that a kind of environment of livestock and poultry cultivation uses, by o-phthalaldehyde(OPA) and the last of the ten Heavenly stems first bromine ammonium and the composite disinfectant formed of other auxiliary material.
Two, background technology
Current livestock and poultry cultivation had entered scale, intensification, automation and Mechanization Development stage already; a large amount of livestock and poultry are collected at together; the problem of bringing thus is: in case the environmental deterioration of livestock and poultry cultivation; microbiological contamination takes place; very easily break out infectious disease, bring massive losses to livestock and poultry breeding industry.Because the research of novel infectious disease vaccine needs longer cycle, the novel infectious disease of prevention and control can only wait measure realize with the emphasis sterilization by strengthening feeding and management, therefore, the environment disinfected of livestock and poultry farm, purification, very important.The common method that purifies the livestock and poultry cultivation environment is to use disinfectant.The kind of disinfectant is more, and mostly be chemicals, can be divided into types such as bases disinfectant, acids disinfectant, phenols disinfectant, aldehyde disinfectant, alcohol disinfectant, halogen disinfectant, oxidants disinfectant, quaternary ammonium disinfectant, volatility alkylating agent and composite disinfection agent by its composition.And the defective that exists because of disinfectant itself in actual use: narrow as antimicrobial spectrum, toxicity is big, cost is high, can not the belt body sterilization etc. the influence of factor, a part of disinfectant uses not extensive at livestock and poultry farm.The disinfectant that generally uses is compound phenols (the agricultural and sideline sterilization prestige of representative products, synergy sterilization prestige), iodine class (the potent iodine of representative products acid iodide thimerosal), quaternary ammonium salts (representative products is visitd only, hundred epidemic diseases are gone out), chlorinated product class (the green power of representative products disappears, speed is gone out No. five) and glutaraldehyde class (the representative products peace is killed) at present, and many products are external product.
Along with the globalization of economic trade, Animal diseases are popular also to present globalization.Research and develop under these circumstances that one or more are novel, efficient, wide spectrum, safety, the disinfectant that has China's independent intellectual property right seems very necessary.
(ortho-phthalaldehyde, OPA) molecular formula is C to o-phthalaldehyde(OPA)
8H
6O
2, molecular weight is 134.13, finished product is faint yellow acicular crystal, and organic solvents such as water-soluble, pure, ether, excitant is little, corrosivity is low, and chemical property is stable.Be used for endoscopy disinfection first in 1994, studies show that o-phthalaldehyde(OPA) (OPA) all has very strong killing action to bacterial propagule, fungi, mycobacterium, virus even some parasite, therefore passed through the U.S. FDA authentication in 1999 as a kind of high effect disinfectants o-phthalaldehyde(OPA) (OPA) thereafter.Domestic research to this disinfectant starts from 2002, and research direction mostly is the effect that o-phthalaldehyde(OPA) is used for medical apparatus sterilizing, number is 200410016142 as Chinese patent application, and denomination of invention is the preparation method of O-phthalaldehyde disinfectant; Application number is 200610037318, and denomination of invention is O-phthalic aldehyde antiseptic sterilization agent and preparation method thereof, and this technology is used for medical apparatus sterilizing; Application number is 200610122699, and denomination of invention is for being the O-phthalaldehyde disinfectant of carrier with oyster shell powder, and this technology is to be used for the shrimp pool, fish pond breed water treatment.O-phthalaldehyde(OPA) in the technique scheme is independent use, does not see the report that is used for the livestock and poultry cultivation field about o-phthalaldehyde(OPA).In addition, use phthalaldehyde to make disinfectant separately, the problem that exists has certain property be infected with when being The field, can stay the stain that is difficult to clean being sterilized body surface, therefore application number is 200510006155, denomination of invention is intended to overcome O-phthalaldehyde disinfectant and uses the defective with certain property be infected with separately for " method that comprises the bactericidal composition of halogenated phthalaldehydes compound and use such compositions for disinfection sterilization ".It is very low to the killing rate of bacillus subtilis, black mutation gemma to studies have shown that concentration is lower than the o-phthalaldehyde(OPA) of 5000mg/L, and this also illustrates can not well satisfy the requirement of eliminating the pathogenic bacteria gemma that exists in the breeding environment (gemma that forms as Bacillus cereus, Bacillus anthracis etc.) when independent its concentration of use o-phthalaldehyde(OPA) is lower than 5000mg/L.
First bromine ammonium in the last of the ten Heavenly stems (Deciquam) has another name called two decyl dimethyl ammonium bromides, and the double-chain quaternary ammonium salt disinfectant has killing action to most cells, fungi and algae, and lipophilic virus is also had certain effect.During its solution state, can dissociate quaternary ammonium salt cationic, combine with phosphate electronegative in the bacterium endochylema membrane phospholipid, low concentration is bacteriostasis, and high concentration plays bactericidal action.Bromide ion strengthens the hydrophily of molecule and lipophilicity, and the energy rapid permeability changes the permeability of film to endochylema membrane lipid layer and protein layer, reaches bactericidal action.Because the last of the ten Heavenly stems, first bromine ammonium only had effect to lipophilic virus, so generally do not use as broad-spectrum disinfectant separately, the compound use of sterilizing of normal and glutaraldehyde, iodine class strengthens its disinfection effect.
