Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of Biocidal algae-killing agent and synthetic method thereof.
Background technology
In half a century in the past, the status of bactericide in cold water process has become and has become more and more important, and that is the problem of microorganism and biological clay, dirt more and more causes the attention of people.Three subject matters in circulation, dirt, deposition and corrosion are different, but are relevant.They are relevant with the microorganism in cooling water system all directly or indirectly.The trouble that in circulation, microorganism causes the soonest, the most obvious.It may cause water quality to worsen rapidly, once biological clay generates in a large number, corrosion-mitigation scale-inhibition medicament that is inefficacy, directly endanger production thus.The bactericidal effect of single bactericide in industrial circulating water is not comprehensive, can not kill the microorganism of all kinds in water; Service time in addition along with a certain bactericide is long, and its bactericidal effect can strengthen along with the pesticide resistance of mushroom and reduce.Select bactericide also will consider that its sludge stripping performance is good.The pollution of industrial circulating water system mainly causes due to microorganism wherein.On the one hand, microorganism causes the direct pollution of water body; On the other hand, the microorganism in industrial circulating water brings great harm to equipment, a large amount of foundry loams that it produces, in cycle water, cause corrosion, foundry loam covers on metal and produces oxygen concentration corrosion cell, and iron is dissolved, the gathering of foundry loam produces fouling and hinders heat transfer, serious meeting blocking pipe.Therefore controlling the microorganism in industrial circulating water and process to control degenerating and reducing the service life that energy consumption extends instrument and equipment of water quality, is the key of circulating water cooling treatment.Adopting bactericide to carry out control to the breeding of microorganism is that one generally adopts and effective method.Water treatment biocide refers to the class reagent for controlling or kill the microorganisms such as bacterium in water and fungi, and they disturb certain aspect of microbial life activity and destroy, thus reaches the effect controlling microbial reproduction.This to proterctive equipment, extension device service life, boost productivity, save water and energy, increase economic efficiency significant.
But current common fungicide bactericidal effect is poor, or has corrosivity to equipment, toxicity is large, can pollute, and easily remain water quality.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of efficient sterilizing algicide and synthetic method thereof.
Biocidal algae-killing agent of the present invention is mainly prepared from by the raw material of following parts by weight:
Epoxychloropropane 2-3 part, dimethylamine 1.5-2.5 part, CAB-35 betain 0.5-1 part, pure water 4-6 part.
CAB-35 betain chemical name: Cocoamidopropyl betaine, chemical structural formula: RCONH (CH

2cOO, CAB-35 betain has excellent dissolubility and compatibility, has sterilization, presses down mouldiness.
The synthetic method of Biocidal algae-killing agent of the present invention mainly comprises the following steps: added by dimethylamine in head tank; Be added in reactor by epoxychloropropane, water and CAB-35 betain, under stirring, 40-48 DEG C condition, drip dimethylamine, time for adding controls at 4-6 hour, at 80-90 DEG C of insulation 3-5 hour, is down to room temperature, blowing, obtains final product.
Preferably, drip dimethylamine time control temperature not higher than 50 DEG C.
Control reaction temperature, effectively can reduce the generation of side reaction.
The present invention is by epoxychloropropane, dimethylamine, the mixing of CAB-35 betain, pass through nucleophilic addition, the epoxy bond open loop of epoxychloropropane, dimethylamine and epoxychloropropane are reacted between 40-48 DEG C, obtain product, then enter holding stage, stir product and the polymerization of CAB-35 betain between soak at about 85 DEG C and generate macromolecule product, product of the present invention is a kind of terpolymer, belongs to aggretion type single dose.
It is good that Biocidal algae-killing agent of the present invention has bactericidal effect, and sludge stripping ability is strong, and low corrosion, nontoxic, pollution-free, the advantages such as noresidue, the scope of application is wider, safety simple to operate, economic and practical.
