Abstract
The invention relates to a preparation method of binapacryl. The preparation method comprises the following steps of firstly, mixing an organic solvent and a wet product of binapacryl, distilling and dehydrating to prepare binapacryl; secondly, distilling and dehydrating through spray heating or membrane evaporator heating by taking the solvent as a carrier to realize the continuous operation of a dehydration process as well as wet-process smashing, blending and packaging processes; and thirdly, simultaneously finishing the operation of complexing maneb and zinc in the organic solvent and the process of dehydrating for crystal transformation. Due to the implementation of the third step, the decomposition of a product is reduced, the harmful impurity and dust pollution is reduced, and a fire accident generated in a product drying process is avoided.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of outfit method of binapacryl.
Background technology
Binapacryl sterling is white powder, industrial goods are canescence or pale yellow powder, there is rotten-egg odour, be insoluble in water, be insoluble to most of organic solvent, but can be dissolved in pyridine, to light, heat, moist instability, easily decomposite carbon disulphide, chance alkaline matter or the material such as copper, mercury all easily decompose releases carbon disulphide and subtracts effect, and volatility is little.So-called protection, exactly for plant provides Zn element, except solving the symptom of scarce zinc, strengthens the ability of opposing disease, thus relatively plays bactericidal action to plant.
Summary of the invention
The present invention proposes a kind of outfit method of binapacryl, and bactericidal range of the present invention extensively, not easily produces resistance, and control efficiency is obviously better than other same series bactericidal agents.Technical scheme is: with the method for binapacryl, and step is:
The first step, binapacryl preparation adopts the wet Product mix distillation dehydration of organic solvent and binapacryl.
Second step take solvent as carrier through spraying heating or through kestner long-tube evaporator heating distillation dehydration, can make dehydration procedure and wet pulverizing, modulation, packaging process continued operation.
3rd step, maneb and zinc in organic solvent complexing complete with a dehydration turn brilliant operation simultaneously
3rd step decreases the decomposition of product, reduces the pollution of objectionable impurities and dust, avoids the generation of firing accident in product drying process.Solvent method dewatering speed of the present invention is fast, and production safety efficiency is high, and simplifies production technology.
Embodiment:
The outfit method of binapacryl, step is:
The first step, binapacryl preparation adopts the wet Product mix distillation dehydration of organic solvent and binapacryl.
Second step take solvent as carrier through spraying heating or through kestner long-tube evaporator heating distillation dehydration, can make dehydration procedure and wet pulverizing, modulation, packaging process continued operation.
3rd step, maneb and zinc in organic solvent complexing complete with a dehydration turn brilliant operation simultaneously
3rd step decreases the decomposition of product, reduces the pollution of objectionable impurities and dust, avoids the generation of firing accident in product drying process.Solvent method dewatering speed of the present invention is fast, and production safety efficiency is high, and simplifies production technology.
