Problems solved by technology

In reality, glyphosate-resistant (GT) traits rely on GT-introduced EPSPS of Agrobacterium agrobacterium, which is insensitive to glyphosate, so glyphosate is taken up by glyphosate-resistant crops and transported to root and shoot growth Part of it even seeps out from the rhizosphere (the soil around the root system), so it will affect the microbial community in the soil and the crops that are subsequently planted in the soil. At the same time, the existing glyphosate preparation process has a long dehydration time, Disadvantages of high energy consumption

Embodiment 1

[0011] S1. After adding 21% of iminodiacetonitrile to 26% NaOH for alkaline hydrolysis, sequentially add phosphorous acid, HCL gas and 52% formaldehyde for condensation reaction, filter to obtain diglyphosate;

[0012] S2, put the bisglyphosate obtained in S1 into a 0.5L stainless steel reactor equipped with a heating device and use activated carbon as a catalyst. Under the conditions of 60°C, an oxygen flow rate of 100mL / min, and a mass fraction of PMIDA of 40%, grass is obtained. Glyphosate;

[0013] S3. Add soft water into the blending kettle, start the agitator, slowly add 30 parts of glyphosate obtained from S2 under stirring, stir to make a uniform paste, and put the isopropylamine into the high level tank for standby; open the jacket Cooling water and gas-phase frozen brine, slowly add 12 parts of isopropylamine dropwise, control the temperature in the kettle to be less than 40°C, add isopropylamine dropwise within 170 minutes, and then stir for 30 minutes; after the ma...

Abstract

The invention discloses a production process of glyphosate isopropylamine water aqua with mass percent of 41%. Liquor concentration of sodium hydroxide is optimized; meanwhile, a practical hydrogen chloride gas is used for acidification of alkaline hydrolysis reaction, so that the dehydration time is reduced, and the steam consumption in a pmida production process is reduced, and the energy-saving and consumption-lowering effect is obvious; the glyphosate obtained by the preparation process disclosed by the invention has a fertility increasing effect and a pesticide effect, and can be used for improving a barren and nutrition-deficient phenomenon of soil after the product is used.

Description

technical field [0001] The invention relates to a process for manufacturing glyphosate isopropylamine saline solution with a mass percentage of 41%. Background technique [0002] Glyphosate herbicide is a destructive (broad-spectrum) pesticide, which can control almost all weeds and has a wide range of uses. However, the herbicide also has certain side effects, which are described below in conjunction with its mechanism: glyphosate binds to enolpyruvate shikimate-3-phosphate synthase (EPSPS) and inactivates it, enolpyruvateshikimate-3-phosphate Synthase is a key enzyme in the plant shikimate synthesis pathway and is necessary for the synthesis of aromatic amino acids, including the essential amino acids phenylalanine, tryptophan and tyrosine, as well as downstream products such as plant growth promoters - indole Acetic acid and plant defense compounds - phytoalexins. In reality, glyphosate-resistant (GT) traits rely on GT-introduced EPSPS of Agrobacterium agrobacterium, wh...
