Abstract
The invention relates to a method for processing a preparation from a raw pesticide structure. The method comprises the following steps: 1) adding a raw pesticide and a dispersion medium, namely water, into a mixing kettle; 2) analyzing the chemical structure of the raw pesticide in the step 1), adding a corresponding alkaline or acidic substance into the mixing kettle when reactive hydrogen or nitrogen atoms of an unshared electron pair exists/exist in the chemical structure of the raw pesticide to form a water-soluble loose compound which is relatively stable, and adding a corresponding organic or inorganic alkali or acid into the mixing kettle when an acidic or alkaline group exists in the chemical structure of the raw pesticide to obviously increase the solubility in the water; 3) adding a surfactant into the mixing kettle under stirring conditions till a material homogeneous phase is transparent; and 4) subpackaging after check and approval. The method for preparing the preparation from the raw pesticide structure, provided by the invention, has simple steps; by using the method, the reactive hydrogen, the nitrogen atoms of the unshared electron pair and the acidic or alkaline group which exists/exist in the chemical structure of the raw pesticide can be effectively neutralized, and the waterborne preparation can be further processed.
Description
Technical field
The present invention relates to a kind of method of utilizing pesticide original medicine structure process preparation.
Background technology
Traditional agricultural chemicals mainly comprises at present: pesticide original medicine, dispersant combination, thickener, antifreezing agent, defoamer and dispersion medium water.But existing agricultural chemicals mainly adopts inflammable, poisonous benzene class, MDF, methyl alcohol equal solvent to process, very easily to environment, and replace inflammable, poisonous benzene class, MDF, methyl alcohol equal solvent to be processed into waterborne preparation with water, become the developing direction of the formulations of pesticide in the world.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of method of utilizing pesticide original medicine structure process preparation, step is simple, can be processed into waterborne preparation, is difficult for environment.
The method of utilizing pesticide original medicine structure process preparation of the present invention, comprises the following steps:
1) in mixing kettle, add pesticide original medicine and dispersion medium water;
2) analytical procedure 1) the former medicine chemical constitution of Pesticides, in pesticide original medicine chemical constitution, there is active hydrogen or the nitrogen-atoms of share electron pair not, in mixing kettle, add corresponding alkali or acid, can form metastable water-soluble loose compound; While having acidity or basic group in pesticide original medicine chemical constitution, in mixing kettle, add corresponding organic or inorganic alkali and acid, so in and salify, can obviously increase solvability in its water, then be uniformly mixed still and make material dissolution complete, mix to homogeneous phase transparent;
3), under stirring condition, in mixing kettle, add surfactant, till material homogeneous phase transparent;
4) check, qualified rear packing, complete the procedure of processing of pesticidal preparations.
The method of utilizing pesticide original medicine structure process preparation of the present invention, described pesticide original medicine is selected from sulfonamides agricultural chemicals, sulfonylurea pesticide, triazole pesticide, plan nicotinoids agricultural chemicals, amino acids agricultural chemicals, it is a kind of to kill in silkworm poison class agricultural chemicals, quaternary ammonium salt agricultural chemicals, carbamate chemicals for agriculture.
Compared with prior art beneficial effect of the present invention is: the method step of pesticide original medicine structure process preparation that utilizes of the present invention is simple, in can be effectively and the active hydrogen existing in pesticide original medicine chemical constitution, not nitrogen-atoms, acidity or the basic group of share electron pair, can be processed into waterborne preparation, for the preparation processing of this type of pesticide species provides a kind of novel processing method.
