Abstract
The invention relates to a biodiesel-based glyphosate environment-friendly aqueous agent, and belongs to the field of new formulations of pesticides. In the environment-friendly aqueous agent, biodiesel is used as a synergist, glyphosate-isopropylammonium is dissolved in water and is compounded with environment-friendly surfactants such as straight-chain fatty alcohol-polyoxyethylene ether, alkyl polyglycosides, polyoxyethylene ether sorbitan aliphatic ester, polyoxyethylene castor oil ether, sodium fatty alcohol-polyoxyethylene ether sulfate and the like and a cosolvent so as to obtain environment-friendly glyphosate aqueous emulsion. In the biodiesel-based glyphosate environment-friendly aqueous agent, ingredients which cause environmental pollution easily or are harmful to environment are avoided, and the requirements of energy conservation and environmental protection are met.
Description
Technical field
The invention belongs to the pesticides new formulation field, what relate to is a kind of glyphosate class weed killer herbicide.
Background technology
Glyphosate Glyphosate is the broad-spectrum herbicide that Monsanto company develops, and is to be that the basis is processed into salt or ester with the glyphosate, because plant is to the absorption difference of acid, high dose, glyphosate easily precipitates when particularly hanging down spouting liquid, and therefore, the activity of acid is usually less than salt.The most frequently used formulation be contain isopropyl amine salt " farming reaches " (Roundup).In the processing of glyphosate formulation, surfactant and synergist are extremely important, and ammonium sulfate and sulfuric acid two ammoniums are activators of using always.Glyphosate isopropyl amine salt is a kind of weak acid, can dissociate in solution, and the anionicsite of molecule is an active component, they can be in flushing liquor with other cations as Ca
2+, Mg
2+, K
+, Na
+, Fe
2+/3+Associate, form the salt that plant is difficult for absorption, and ammonium sulfate and sulfuric acid two ammoniums can stop the generation of this antagonism salt, thereby form glyphosate-NH
4 +Rapidly by plant absorbing.Organic silicon surfactant is designated as the indispensable auxiliary agent of glyphosate in New Zealand, but the price of organic silicon surfactant is more expensive, and has residual after using.
Biodiesel is to carry out obtaining after the ester exchange reaction with methyl alcohol under the effect of strong acid, alkali with soybean oil, palm oil, vegetable seed wet goods vegetable oil, and its main component is a methyl oleate.Because it is natural that vegetable oil derives from, and environment is not had harm, low price can be used as synergist and oiliness surfactant, is used to prepare the gyphosate solution of natural green environmental protection, meets energy conservation and environment protection.
Summary of the invention
The objective of the invention is in order to provide a kind of is synergist with the biodiesel, glyphosate isopropyl amine salt is dissolved in the water, and is prepared into aqua with other environment-friendly type emulsifier configuration, obtains the environment-friendly type gyphosate solution.
Technical scheme of the present invention: a kind of glyphosate environment-friendly type aqua that uses biodiesel as synergist, with biodiesel as synergist, glyphosate isopropyl amine salt is dissolved in the water, it is composite to use multiple environment-friendly type emulsifier such as straight-chain fatty alcohol APEO, alkyl polyglycoside, anhydrous sorbitol polyoxyethylene ether fatty ester, castor oil polyoxyethylene ether, sodium sulfate of polyethenoxy ether of fatty alcohol and cosolvent to carry out subsequently, obtains the glyphosate isopropyl amine salt aqueous emulsion.
Described straight-chain fatty alcohol APEO, for the carbon number of straight-chain fatty alcohol is 8-10,12-14, the oxirane adduct number is 3-20.
Described alkyl polyglycoside, alkyl carbon number are 8-10,12-14,8-14, alkyl glycoside active matter content % 〉=50, alkyl glycoside sugar degree of polymerization 1.4-1.6.
Described anhydrous sorbitol polyoxyethylene ether fatty ester is polyoxyethylene sorbitol acid anhydride mono laurate fat, polyoxyethylene sorbitol acid anhydride list palmitic acid lipid, polyoxyethylene sorbitol acid anhydride monostearate, polyoxyethylene sorbitol acid anhydride list olein, polyoxyethylene sorbitol acid anhydride Triolein.
Described castor oil polyoxyethylene ether, oxirane adduct number are 10-130.
Described sodium sulfate of polyethenoxy ether of fatty alcohol, oxirane adduct number are 2-3.
Described cosolvent is methyl alcohol, ethanol, n-butanol, isobutanol, normal propyl alcohol, n-octyl alcohol, ethylene glycol.
A kind of preparation process of using biodiesel as the glyphosate environment-friendly type aqua of synergist:
The anhydrous sorbitol polyoxyethylene ether fatty ester is added in the biodiesel, glyphosate isopropyl amine salt, anhydrous sorbitol polyoxyethylene ether fatty ester, straight-chain fatty alcohol APEO, alkyl polyglycoside, castor oil polyoxyethylene ether, sodium sulfate of polyethenoxy ether of fatty alcohol and cosolvent are added be made into water in the entry.Disperse to shear biodiesel in the mixer in high shear, slowly water is added in the biodiesel simultaneously and mix, obtain the aqua of transparent and stable.
The consumption of described glyphosate isopropyl amine salt is the 10%-70% of aqua gross mass.
The consumption of described biodiesel is the 5%-20% of aqua gross mass.
The consumption of described anhydrous sorbitol polyoxyethylene ether fatty ester is the 0.1%-5% of aqua gross mass.
