Description
Technical field
The present invention relates to technical field of pesticide, prepare glufosinate-ammonium salt with glufosinate-ammonium intermediate for raw material particularly to a kind of
The method of solid preparation.
Background technology
Glufosinate-ammonium, is often referred to glufosinate-ammonium ammonium salt (glufosinate-ammonium being mentioned below is all referring to glufosinate-ammonium ammonium salt), be a kind of efficiently,
Wide spectrum, the nonselective herbicide of low toxicity, can be used for the preventing and treating such as orchard, vineyard, bare place, potato fields annual and for many years
Raw dicotyledonous and grassy weed, is herbicide of greatest concern after glyphosate.Glufosinate-ammonium system the most on sale
Agent is mainly water preparation and suitable solvents, but water preparation and soluble liquid packed and transported cost is high, metering inconvenience, there is also
The problems such as flocculation, crystallization, not shelf-stable, easy decomposition.
Along with the development in market, people are more and more urgent for the demand of glufosinate-ammonium solid preparation, presently disclosed grass ammonium
Phosphine solid preparation is mainly with glufosinate-ammonium as raw material, coordinates and prepares gained with corresponding filler and auxiliary agent.It is well known, however, that
The preparation process of glufosinate-ammonium is the most numerous and diverse, and the recovery relating to the purification of glufosinate-ammonium, the process of by-product and solvent is the most sharp
With etc. process, equipment requirements is high, complex operation, and production cost is high.Further, glufosinate-ammonium has the strongest hygroscopicity, in water
Dissolubility is 1370g/L, in processing, packaging, is easy to moisture absorption, deliquescence and caking in storage process, affects the quality of product
And use.
Summary of the invention
In view of this, the invention provides a kind of stable storage, the solid preparation that raw material is conveniently easy to get, this solid preparation with
Intermediate compound glufosinate-ammonium hydrochlorate in glufosinate-ammonium preparation process is that raw material is prepared from, and coordinates with solid base, auxiliary agent, filler
And pyrophosphate, solid preparation each constituent mass percentage ratio that the present invention provides is:
Glufosinate-ammonium hydrochlorate: 1～83%
Solid base: 0.2～48%
Auxiliary agent: 0～20%
Filler: 0～98.8%
Pyrophosphate: 0～10%
Can be more preferably:
Glufosinate-ammonium hydrochlorate: 20～83%
Solid base: 4～48%
Auxiliary agent: 0～20%
Filler: 0～76%
Pyrophosphate: 0～3%
Solid base described in above-mentioned raw materials is potassium carbonate, potassium bicarbonate, tripotassium phosphate, dipotassium hydrogen phosphate, sodium carbonate, carbon
One in acid hydrogen sodium, tertiary sodium phosphate, disodium hydrogen phosphate, ammonium hydrogen carbonate, triammonium phosphate and diammonium phosphate.It is preferably hydroxide
One in potassium, sodium hydroxide, ammonium carbonate, ammonium hydrogen carbonate.
Described auxiliary agent include being not limited in wetting agent, dispersant, synergist one or more.Including glucosides,
Tallow amine, glycine betaine, polyoxyethylenated alcohol sodium sulfate, sodium alkyl benzene sulfonate, sodium lauryl sulphate, alkylol polyoxy second

Glufosinate-ammonium hydrochlorate is acid solid, and direct cooperation is prepared as solid preparation use with filler and auxiliary agent and can cause meeting
Destroy the effectiveness of soil nutrient, crop is produced toxic action.Glufosinate-ammonium hydrochlorate dissolubility in water is 600g/L, molten
When water, the most few partial ionization is glufosinate-ammonium radical ion, and glufosinate-ammonium radical ion is the key component of herbicide, therefore
Glufosinate-ammonium hydrochlorate is used alone its drug effect and can not show a candle to glufosinate-ammonium, and this is also not to be used alone glufosinate-ammonium hydrochlorate to prepare preparation
Reason.
The solid preparation that the present invention provides not only comprises glufosinate-ammonium hydrochlorate and further comprises solid base, the careless ammonium of solid-state form
Phosphonium salt hydrochlorate and solid base are less likely to occur reaction in the presence not having solvent, and because the hygroscopicity of glufosinate-ammonium hydrochloric acid is wanted
Significantly better than the salt of other forms of glufosinate-ammonium, so the preparation of more conducively solid preparation.The solid preparation that the present invention provides exists
Being put in a certain amount of water before using, it is raw that effective ingredient glufosinate-ammonium hydrochlorate and solid base will occur to neutralize reaction immediately
Become water miscible glufosinate-ammonium salt.
The present invention is also added into a small amount of pyrophosphate simultaneously, and it is effective that the existence of pyrophosphate can ensure that in solid preparation
Composition does not reacts in the environment that humidity is bigger, and pyrophosphate can also play certain slow releasing function, when solid
When body preparation is dissolved in water, can be with the pH value of regulation system, it is to avoid prepare gained glufosinate-ammonium salt peracid or cross alkali, it is to avoid unreacted
Glufosinate-ammonium hydrochlorate destroys the effectiveness of soil nutrient completely, and crop is produced toxic action.Last pyrophosphate is all right
With the trace element complexation in soil, become the carrier of trace element, the fertilizer efficiency of soil can be improved.
The present invention is relative to the advantage of prior art:
1, the present invention use glufosinate-ammonium hydrochlorate as raw material, simple and easy to get, it is to avoid glufosinate-ammonium water soluble salt synthesized
Tedious steps in journey, greatly simplify the technological process that glufosinate-ammonium produces, reduces raw material and energy resource consumption, and operate
Simple and convenient, save equipment investment, reduce preparation production cost, have great economic benefit and wide application prospect.
2, the present invention is because simplifying the synthesis technique of glufosinate-ammonium salt, considerably reduces generation and the process of the three wastes, it is to avoid
The use of organic solvent, environmentally friendly, produce, use during VOC index low.
3, invention formulation product is difficult to the moisture absorption, stable, crop will not be produced toxic action, and can change after using
The fertilizer efficiency of kind soil.
4, the solid preparation that the present invention provides, preparation simplicity, it is easy to operation, it is achieved that the industrialization of glufosinate-ammonium solid preparation
Produce, and product production, pack, store, transit link all has a clear superiority in.Processing, packaging process need not airtight
Environment, reduces and produces equipment requirements, can greatly reduce equipment investment cost and packaging Holding Cost.
5, invention formulation product is not because using organic solvent in process of production, to health fanout free region, to environment
Pollution-free, it is suitable for the controlling weeds requirements such as China orchard, bare place.
6, invention formulation product is solid preparation, is not related to preparation stabilization sex chromosome mosaicism, can expand auxiliary agent range and
Usage amount, activity of weeding is apparently higher than 200g/L glufosinate-ammoniumaqua aqua product, and effective ingredient mu usage amount can reduce, and meets country
Pesticide reduction requirement.
