Embodiment 1

[0015] Example 1 Get 425g of bisglyphosate (96% content) in a stirred flask, add 260g sulfuric acid (98% content) and 0.5g lanthanum nitrate, heat up to 95°C ± 5°C, and react for 3-4 hours to no Bubbles are generated to obtain the mixed glyphosate mother liquor. In mixed glyphosate mother liquor, add isopropylamine salt 150g, and add alkyl glucoside 30g, naphthalene sulfonate 25g, thickener xanthan gum 1g, antifreeze agent ethylene glycol 30g, defoamer silicone 0.01g simultaneously, The remaining amount was replenished to 1000 g with water to obtain a 30% glyphosate (calculated as glyphosate acid) suspension containing bisulfate ions.

Embodiment 2

[0016] Example 2 Get 425g of bisglyphosate (96% content) in a stirred flask, add 630g sulfuric acid (98% content) and 0.5g cerium nitrate, heat up to 75°C ± 5°C, react for 3-4 hours to no Bubbles are generated to obtain the mixed glyphosate mother liquor. Add 25g of ammonia to the mixed glyphosate mother liquor, and at the same time add 30g of alkyl glycoside, 25g of naphthalene sulfonate, 1g of thickener xanthan gum, 30g of antifreeze ethylene glycol, 0.01g of antifoaming agent silicone, and the balance Make up to 1500g with water, promptly make the 20% glyphosate (calculated as glyphosate acid) suspension concentrate containing bisulfate ion.

Embodiment 3

[0017] Example 3 Take 425g of bisglyphosate (96% content) in a stirred flask, add 260g sulfuric acid (98% content) and 20g polyphosphoric acid, heat up to 130°C ± 5°C, and react for 1-2 hours until there are no bubbles Produced to obtain mixed glyphosate mother liquor. Add potassium hydroxide 150g in the mixed glyphosate mother liquor, and add alkyl glucoside 30g, naphthalene sulfonate 25g, thickener xanthan gum 1g, antifreeze agent ethylene glycol 30g, defoamer silicone 0.01g simultaneously, The remaining amount was replenished to 1000 g with water to obtain a 30% glyphosate (calculated as glyphosate acid) suspension containing bisulfate ions.

[0018] Two, the preparation of 30% glyphosate (calculated as glyphosate acid) aqua containing sulfate ion:

Abstract

The invention relates to a preparation method of glyphosate water-based preparation containing sulfate radical or bisulfate radical ions. The glyphosate is mixed glyphosate liquid prepared by carrying out a sulfuric acid oxidization method on PMIDA, or mixed glyphosate salt solution is formed by continuously adding alkali. Then, the obtained mixed liquid is added with surface active agent to prepare the glyphosate composition water-based preparation containing the sulfate radical or bisulfate radical ions; and in the preparation, the glyphosate has the mass percent (based on glyphosate acid) more than or equal to 20%, the sulfate radical or bisulfate radical ions more than or equal to 20% and the mass percent ratio between the glyphosate and the sulfate radical or bisulfate radical ions is 1:2-2:1. The preparation technique of the glyphosate needs not to separate glyphosate technical in advance, thus greatly reducing the input of production equipment and manpower, reducing the emission of waste water in the production process, saving resources and being beneficial to environmental protection; furthermore, the preparation contains more sulfate radical or bisulfate radical ions, thus greatly improving the drug effect, reducing the dosage of the glyphosate and saving the resources.

Description

technical field [0001] The invention relates to a preparation method of a glyphosate preparation, in particular to a preparation method of a glyphosate water-based preparation containing sulfate ions or bisulfate ions. Background technique [0002] Glyphosate (glyphosate), scientific name N-(phosphonomethyl) glycine, N-(phosphonomethyl) aminoacetic acid (Phosphonomethyl Imino Acetic Acid), is an organophosphorus herbicide. As a non-selective, non-residue post-emergence herbicide, glyphosate is absorbed through plant leaves and non-woody stems and leaves, and is transmitted to all parts of the plant. Leaf weed is very effective. The most prominent feature of glyphosate is that it can be absorbed by stems and leaves and transmitted downwards to underground rhizomes and tillers, which is extremely destructive to the underground tissues of weeds. In my country, glyphosate has been widely used and is the most widely used herbicide in my country. However, during the use of glyp...
