Problems solved by technology

However, in the existing ammonium salt synthesis, the glyphosate raw drug or wet block reacts with ammonia gas, liquid ammonia or ammonia water, and fails to take into account the recovery and use of glyphosate in the mother liquor
For example, the invention patent application with publication number CN1260349 discloses the technical scheme of the glyphosate ammonium salt formed by the reaction of glyphosate and liquid ammonia; Phosphate ammonium salt technical scheme; the invention patent application with publication number CN1724547 discloses a technical scheme for synthesizing glyphosate ammonium salt with glyphosate as the stationary phase and ammonia water as the mobile phase, and the obtained glyphosate ammonium salt is not suitable for the same The solid preparation of glyphosate ammonium salt is directly made into the reaction vessel, and the ammonium glyphosate salt needs to be harvested separately and then processed into a solid ammonium salt preparation, and the recovery and use of glyphosate in the glyphosate mother liquor has not been considered. Poor economic benefit

Embodiment 1

[0021] A kind of production method of glyphosate granule, mainly is that glyphosate technical substance and ammonium bicarbonate are solidified and reacted together to form glyphosate ammonium salt, then add disintegrating aid, pH adjusting agent and special auxiliary agent, Mix evenly and granulate into glyphosate granules. Specific steps are as follows:

[0022] Put 72.5 kg of glyphosate technical material into the mixing tank, start stirring, and put 36 kg of ammonium bicarbonate into the mixing tank. Ammonium bicarbonate should be slightly excessive (the molar ratio of glyphosate original drug to ammonium bicarbonate can be 1:1.05-1.10), in order to ensure complete reaction. Continue to put 6kg of ammonium sulfate (disintegrant aid) and 6kg of pH regulator (sodium tripolyphosphate) into the mixing tank, adjust the pH at 4.5-6.5, and control the temperature of the mixing tank at 30°C-40°C. Continue to stir. Add 8 kg of special additives (alkyl glucoside or tallow amine p...

Embodiment 2

[0024] A kind of production method of glyphosate granule, process is as follows:

[0025] Put 72.5 kg of glyphosate technical material into the mixing tank, start stirring, and put 38 kg of ammonium bicarbonate into the mixing tank. Ammonium hydrogen should be slightly excessive, in order to ensure complete reaction. Continue to put 6kg of ammonium sulfate (disintegrant aid) and 6kg of pH regulator (sodium tripolyphosphate) into the mixing tank, adjust the pH at 4.5-6.5, and control the temperature of the mixing tank at 30°C-40°C. Continue to stir. Add 8 kg of special additives (alkyl glucoside or tallow amine polyoxyethylene ether) into the mixing tank again. After the raw and auxiliary materials are fed, continue to stir for 4-5 hours, control the temperature in the mixing tank at 60°C, discharge the materials to the granulator for granulation after the reaction, and send the granulated materials from the conveyor belt to the conveyor belt of the microwave dryer In the ho...

Embodiment 3

[0027] A kind of production method of glyphosate granule, process is as follows:

[0028] Put 72.5 kg of glyphosate technical material into the mixing tank, start stirring, and put 36 kg of ammonium bicarbonate into the mixing tank. Ammonium hydrogen should be slightly excessive, in order to ensure complete reaction. Continue to put 8kg of ammonium sulfate (disintegrant aid) and 6kg of pH regulator (sodium tripolyphosphate) into the mixing tank, adjust the pH at 4.5-6.5, control the temperature of the mixing tank at 30°C-40°C, after feeding Continue to stir. Add 8 kg of special additives (alkyl glucoside or tallow amine polyoxyethylene ether) into the mixing tank again. After the raw and auxiliary materials are fed, continue to stir for 4-5 hours, control the temperature in the mixing tank at 60°C, discharge the materials to the granulator for granulation after the reaction, and send the granulated materials from the conveyor belt to the conveyor belt of the microwave dryer ...

Abstract

The invention discloses glyphosate granules and a production method thereof. The glyphosate granules are composed of the following components, in parts by weight: 72.5 parts of a glyphosate original pesticide, 35.5-40 parts of ammonium bicarbonate, 5-8 parts of an auxiliary disintegrating agent, 5-8 parts of a pH modifier, and 6-10 parts of a special auxiliary agent. According to the glyphosate granules and the production method thereof, the process is simple, operation is simple and convenient, and compared with a glyphosate isopropylamine water product, the obtained glyphosate ammonium granule product has no obviously different weed removing effects, can meet use requirements, and has a higher utilization ratio of the glyphosate original pesticide; the produced product is easy to packageand convenient for transportation, and has greater production and usage advantages and extremely good practicability.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a glyphosate granule and a preparation method thereof Background technique [0002] Glyphosate is a non-selective, non-residual herbicide that kills perennial root weeds and is widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits enolpyruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikimelin to phenylalanine, tyrosine and tryptophan, interfering with protein synthesis and causing plant death. Glyphosate is absorbed by the stems and leaves and then transmitted to various parts of the plant. It can control more than 40 families of plants such as monocots and dicotyledons, annuals and perennials, herbs and shrubs. Glyphosate quickly combines with metal ions such as iron and aluminum to lose its activity after entering the soil, and has no adverse effects on the seeds and soil microorganisms hidden in the so...
