Detailed description of the invention
Fig. 1 is the continuous preparation method flow diagram of pesticide dimethylamine salt aqua provided by the invention.
Specific embodiment
For a further understanding of the present invention, the preferred embodiment of the invention is described below with reference to embodiment, still
It should be appreciated that these descriptions are only further explanation the features and advantages of the present invention, rather than to the claims in the present invention
Limitation.
For the intermittent production operation of aqueous pesticide solution in the prior art, personnel safety is low, product production capacity is low, quality mark
The problem of quasi- controlling difference, the embodiment of the invention discloses a kind of continuous preparation method of pesticide dimethylamine salt aqua, the party
Method can realize the continuous production of pesticide dimethylamine salt aqua, and do not need personnel and directly operate, highly-safe, and aqua is prepared
Conveniently, accuracy rate is higher.The preparation flow of the application pesticide dimethylamine salt aqua is as shown in Figure 1, specifically, include:
Pesticide original medicine is mixed in preparing kettle with water, is persistently led to according to the reaction ratio of pesticide original medicine and dimethylamine gas
Enter dimethylamine gas, then be continually fed into pesticide original medicine and water, prepares the full rear overflow of kettle to next preparation kettle, until the last one is matched
Kettle overflow processed goes out material, and the material is pesticide dimethylamine salt aqua；It is described prepare kettle number >=2 and be arranged in series.
In the preparation process of pesticide dimethylamine salt aqua, the pesticide original medicine of the application preferred pin pair is 2,4- Dichlorophenoxy
Acetic acid, dicamba or glyphosate, i.e. the application are prepared for 2,4- dichlorphenoxyacetic acid dimethylamine salt aqua, wheat by the above method
Grass fear dimethylamine salt aqua or glyphosate dimethylamine salt aqua.In order to guarantee preparation aqueous pesticide solution meet reaction proportion and
The application demand of aqueous pesticide solution, for above-mentioned effective component, the molar ratio of the pesticide original medicine and dimethylamine gas is 1:(0.9
~1.6), in a particular embodiment, the molar ratio of the pesticide original medicine and dimethylamine gas is 1:(1.0~1.3).
Specifically, pesticide original medicine and soft water are added to preparation first in the preparation process of pesticide dimethylamine salt aqua
It is mixed in kettle, and opens stirring；The kettle of preparing is the vessel well known to those skilled in the art for preparing pesticide, to this application
Without particularly limiting.
It is added in pesticide original medicine and soft water to after preparing kettle, then starts to be passed through dimethylamine gas；In entire configuration process
In, dimethylamine gas is continually fed into preparation kettle, and being passed through for dimethylamine gas meets above-mentioned molar ratio, to guarantee pesticide original
Medicine is sufficiently reacted with dimethylamine gas.It is controlled during being passed through dimethylamine gas by pressure pressure tank, so that dimethylamine
The pressure of gas is 0.01~0.09MPa, and in a particular embodiment, the pressure of the dimethylamine gas is 0.03~0.08MPa,
More specifically, the pressure of the dimethylamine gas is 0.01~0.03MPa, 0.03~0.04MPa or 0.07~0.08MPa.Institute
The flow velocity for stating dimethylamine gas is 0.5~3T/h, and in a particular embodiment, the flow velocity of the dimethylamine gas is 0.6~1.8T/
h.The restriction of above-mentioned dimethylamine gas pressure and flow velocity just can guarantee the dimethylamine amount and effective component for eventually entering into and preparing in kettle
Match, reach the delay reaction time in kettle carries out next preparation kettle again.The process for preparing kettle is passed through in dimethylamine gas
In, pesticide original medicine and dimethylamine gas are constantly in reactiveness, after dimethylamine gas is passed through a period of time, specially diformazan
When amine gas intake is the 80%~90% of total amount, starts to be continually fed into pesticide original medicine and soft water, pesticide original medicine is added herein
Specifically as follows with the proportion of soft water: the addition of pesticide original medicine according to the addition of the reaction ratio of dimethylamine gas, it is soft
The addition of water is consistent with the concentration of the aqueous pesticide solution finally configured.The soft water of the application divides in the manner described above with pesticide original medicine
It criticizes and is added, if being added at one time it cannot be guaranteed that ensured sustained development prepares and reaction effect, with being slowly added into for effective component, material
Next preparation kettle is more and more overflowed to, if being added at one time, then it cannot be guaranteed that residence time in kettle.
With the progress of reaction, it is continuously added into pesticide original medicine and soft water, until first preparation kettle is full.The application is provided with
Multiple concatenated preparation kettles, in order to which the material for being conducive to overflow is directly entered next preparation kettle, the multiple height for preparing kettle
It is preferred that successively reducing.In this application, preferably concatenated number >=2 of preparation kettle, in a particular embodiment, the preparation kettle
Number be 2~5.With the progress of reaction and the addition of raw material, after first preparation kettle is full, continue in first preparation kettle
In be passed through dimethylamine gas and corresponding pesticide original medicine and soft water, then react after material be constantly spilled over to next match
Kettle processed, until the material of spilling is pesticide dimethylamine salt aqua after the last one prepares kettle completely.In order to make pesticide dimethylamine salt
Aqua is more conducive to use, and further includes auxiliary agent in the pesticide dimethylamine salt aqua, the application is preferably in the last one preparation kettle
Auxiliary agent is added, so that it includes auxiliary agent that the last one, which is prepared in the material that overflow goes out in kettle, i.e., includes in pesticide dimethylamine salt aqua
Auxiliary agent.
This application provides a kind of continuous preparation methods of pesticide dimethylamine salt aqua, are to continue dimethylamine gas
Be passed through the water slurry of effective component, by prepare kettle series connection, raw medicine and water and dimethylamine according to a certain ratio, persistently plus
Enter, sustained response, by the control to pressure, flow and proportion, obtains qualified dimethylamine aqua product, whole operation mistake
Cheng Junwei automatic control, the dimethylamine salt aqua continuous production that personnel can be realized by control room, is waved to change dimethylamine
Hair, personnel cost is high, and safety is low, and production capacity is low, the uncontrollable problem of quality.
