Abstract
The present invention discloses a manufacturing method of the high-efficient, innoxious and safe sterilizing and alga-destroying thing used in the natatorium. The method mainly comprises the following steps: under the protection of the inert gases, the frank-chain fat diamines is reacted with the dihydroxy ethyl aether in the water solution, and then are treated by the treating thing. The reaction liquid is adjusted to litmusless. The sterilizing and alga-destroying thing with the structure can be obtained. Thereinto, R1, R2, R3, R4 are respectively selected from H and a saturated or unsaturated alkyl including at least one carbon atom; m is among 1 to 14; n is among 1 to 5000; X represents a halogen ion combined with a positive ion. The product can be widely used for sterilizing and alga-destroying for the natatorium.
Description
Technical field
The present invention relates to a kind of preparation method of disinfection algicide for swimming pool.
Background technology
Generally use chlorine, dioxide peroxide, clorox as disinfection algicide for swimming pool at present, chlorine must be closed Shi Caike at swimming pool and carry out sterilization algae removal because human body is had pungency and danger; Though clorox danger reduces greatly, pungency still exists; Dioxide peroxide is non-stimulated to human body, but preparation is difficult, product stock is unstable.
Summary of the invention
Technical problem to be solved by this invention is: the preparation method that a kind of disinfection algicide for swimming pool efficient, nontoxic, safe in utilization will be provided.
For solving the problems of the technologies described above; the technical solution used in the present invention is: the preparation method of described disinfection algicide for swimming pool; it is characterized in that: comprise the steps: under certain temperature T1; and under protection of inert gas; straight-chain fat diamine is added in the mixed solution of dihalo-ethyl ether and water; be warming up to the T2 reaction then and obtain a kind of polyquaternium; the pH value of monitoring reaction liquid; after the pH of reaction solution value is less than A; reaction solution is cooled to T3; adding post-treatment agent then handles; after post-treatment agent is handled, again reaction solution is transferred to neutrality, promptly get required Biocidal algae-killing agent.This Biocidal algae-killing agent has following general formula:
Wherein R1 be selected from H, by a kind of saturated or undersaturated alkyl that has at least one carbon atom, R2 is selected from H, by a kind of saturated or undersaturated alkyl that has at least one carbon atom, R3 is selected from H, by a kind of saturated or undersaturated alkyl that has at least one carbon atom, R4 is selected from H, by a kind of saturated or undersaturated alkyl that has at least one carbon atom; M is 1～14; N is 1～5000; X-represents a kind of halide-ions that combines with positively charged ion.
The mol ratio of above-mentioned straight-chain fat diamine and dihalo-ethyl ether is 1.5: 1～1: 1.5.
Above-mentioned temperature T 1 is 30-90 ℃, preferred 50-70 ℃; T2 is 60-150 ℃, preferred 90-120 ℃.T3 is 0-70 ℃, preferred 30-60 ℃.
Above-mentioned pH value A is 4.0-7.0.
Above-mentioned rare gas element can be nitrogen, carbonic acid gas.
Above-mentioned X-can be selected from fluorine, chlorine, bromine, iodine.
Above-mentioned post-treatment agent is selected from sodium bisulfite, S-WAT, hydrogen peroxide, Sodium Pyrosulfite, sodium hydroxide, Sulfothiorine, sodium borohydride.And the add-on of post-treatment agent is 0.01%～2% of a reaction solution total mass.
The invention has the beneficial effects as follows: preparation method's environmental protection of the present invention, there are not any three wastes, no high temperature, high pressure; Resulting product has excellent biodegradability, and eco-toxicity is low, has excellent Environmental compatibility and skin-friendliness, to human body nonirritant, nontoxic.
