Problems solved by technology

[0004] Glyphosate ammonium salt and sodium salt are not very soluble, and the load of liquid preparation is low. The preparation of high-load dry preparation requires solid precipitation, and the drying process is complicated; it can be made into relatively high-load glyphosate potassium salt and organic amine salt. Salt liquid salt, but due to the influence of some known impurities such as formaldehyde and formic acid in the original glyphosate drug, the single-preparation salt with a higher concentration is unstable, resulting in turbidity, precipitation, or a decrease in glyphosate content after long-term storage, etc.

Embodiment 1

[0014] The technical glyphosate is prepared as a potassium salt with a concentration of 50-75% w / w according to a conventional method, and then 0.1-0.2% (can be 0.1%, 0.15%, or 0.2%) of potassium salt is added to the glyphosate potassium salt. Ammonia (or amino-containing compounds such as isopropylamine and ethanolamine) can be used to obtain a high-load glyphosate potassium salt stable liquid.

Embodiment 2

[0016] The glyphosate former medicine is made concentration is the glyphosate isopropylamine salt of 41~65% by conventional method, then in the glyphosate isopropylamine salt, add 0.2~0.5% (can be 0.2%, 0.35%, 0.5%) potassium hydroxide to obtain a high-load glyphosate salt stable liquid.

Embodiment 3

[0018] The potassium salt of glyphosate and the isopropylamine salt of glyphosate or the ethanolamine salt of glyphosate prepared by the conventional method are 1~10:10~1 (example 1:10, 1:5, 1:1,5: 1, 10:1) by weight ratio to obtain a high-load glyphosate salt stable liquid.

Abstract

The invention discloses a high-capacity glyphosate salt stabilization liquid, in which glyphosate salt is added with stabilizator. The invention can prevent glyphosate salt liquid transfer to other material and ensure long-term stable storage.

Description

Technical field: [0001] The invention relates to a stable glyphosate preparation. Background technique: [0002] Glyphosate is a conductive broad-spectrum herbicide, its solubility in acid and water is only 12g / L (25°C), so it is usually made into a water-soluble salt, which is convenient for storage, transportation and use. Glyphosate is widely used Sodium salt, potassium salt, ammonium salt and organic amine salt, such as isopropylamine salt, ethanolamine salt, etc. [0003] In order to facilitate storage, transportation and use, it is hoped to make a high-load glyphosate salt preparation, but many difficulties are encountered in the actual production process: [0004] Glyphosate ammonium salt and sodium salt are not very soluble, and the load of liquid preparation is low. The preparation of high-load dry preparation requires solid precipitation, and the drying process is complicated; it can be made into relatively high-load glyphosate potassium salt and organic amine sal...
