Embodiment 1

[0024] Add 50 parts of dry glyphosate acid, 25 parts of dimethylamine hydrochloride, and 10 parts of pH regulator sodium carbonate into a gravity-free mixer, start the mixer and mix for 0.3 to 0.5 hours, and then pour into the mixer Add 5 parts of surfactant alkyl glycoside auxiliary agent in the mixture, and mix for 0.5 hour to obtain 50% glyphosate dimethylamine salt powder product. Further, the above-mentioned powder can be compressed into other solid dosage forms such as granules and tablets by using a granulator and a tablet press.

Embodiment 2

[0026] Add 20 parts of glyphosate acid dry product, 15 parts of dimethylamine acetate and 35 parts of adsorbent white carbon black, 10 parts of pH regulator sodium carbonate, 3 parts of filler sulfuric acid in the gravity-free mixer ammonium, start the mixer and mix for 0.3 to 0.5 hours, then add 7 parts of surfactant tallow amine auxiliary agent into the mixer, and mix for 0.5 hours to obtain a 20% glyphosate dimethylamine salt powder product. Further, the above-mentioned powder can be compressed into other solid dosage forms such as granules and tablets by using a granulator and a tablet press.

Embodiment 3

[0028] Add 90 parts of dry glyphosate acid, 6 parts of dimethylamine hydrochloride, and 2 parts of pH regulator sodium carbonate into the gravity-free mixer, start the mixer and mix for 0.3 to 0.5 hours, and then pour into the mixer Add 2 parts of surfactant betaine auxiliaries to the mixture, and mix for 0.5 hour to obtain a 90% powder product containing glyphosate dimethylamine salt. Further, the above-mentioned powder can be compressed into other solid dosage forms such as granules and tablets by using a granulator and a tablet press

Abstract

The invention discloses a solid herbicide composition, comprising the following components of, by weight, 20%-90% of glyphosate acid, 1%-50% of a dimethylamine salt, a pH conditioning agent and 2%-30% of an auxiliary agent. The solid herbicide composition decreases the synthetic process for the raw material of a glyphosate dimethylamine salt, reduces resource consumption energy consumption, and is helpful to realize low-carbon economy. The method has relatively large competitive advantage by greatly reducing the cost of the final glyphosate dimethylamine salt.

Description

technical field [0001] The invention relates to the technical field of agricultural herbicides, in particular to a solid herbicide composition. Background technique [0002] Glyphosate is a broad-spectrum herbicide. Since the solubility of glyphosate in water is very low, in practical applications, glyphosate is usually prepared as a water-soluble salt. The most widely used glyphosate soluble salts are mainly isopropylamine salt, ammonium salt, potassium salt and dimethylamine salt, among which glyphosate dimethylamine salt has the best effect among glyphosate soluble salts and is also used globally One of the widest varieties. [0003] Glyphosate dimethylamine salt generally refers to the monodimethylamine salt of glyphosate, and it is in the form of an aqueous solution. Since the water preparation contains a large amount of water, it brings many inconveniences such as packaging, transportation and storage, and increases the cost at the same time. [0004] With the devel...
