Problems solved by technology

[0007] Existing glyphosate isopropylamine salts often have low production efficiency. Stirring tanks are often used in the production of glyphosate isopropylamine salts. The existing stirring tanks are difficult to control the amount of feed, causing the materials in the stirring tanks to be Blockage due to excessive material volume, and insufficient stirring in the existing mixing tank, and the inner wall is not easy to clean

Abstract

The invention discloses an efficient production method of glyphosate isopropylamine salt. The method comprises the following steps: S1, weighing the following raw materials in parts by weight: 10-20 parts of glyphosate, 15-20 parts of isopropylamine and 30-40 parts of water; S2, simultaneously adding glyphosate and water into a stirring tank while stirring, and carrying out stirring for 11.5 hoursunder the condition that a temperature is in a range of 30 DEG C to 32 DEG C; S3, putting isopropylamine into a reaction kettle, dropwise adding a material A obtained in the step S2 into the reactionkettle while stirring, and carrying out stirring for 1-2 hours at a temperature of 30-32 DEG C; and S4, controlling the temperature in the reaction kettle to be 30-31 DEG C through a condenser when stirring has been lasted for 2-2.5 hours, and controlling the temperature in the reaction kettle to be 32-40 DEG C when stirring has been lasted for 2.5-3 hours until a pH value in the reaction kettleis smaller than 7, thereby obtaining the glycyl isopropylamine salt.

Description

technical field [0001] The invention relates to the technical field of glyphosate isopropylamine salt production, in particular to a high-efficiency production method of glyphosate isopropylamine salt. Background technique [0002] Glyphosate is an effective active chemical ingredient in many widely used herbicides, and today, technical glyphosate can be processed into 10% glyphosate water solution, 41% glyphosate isopropylamine saline solution, 62 % Glyphosate isopropylamine salt solution, mainly through the systemic conduction type broad-spectrum herbicide, mainly inhibits the enol aceruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikime to phenylalanine, ester The conversion of amino acid and tryptophan interferes with protein synthesis, leading to plant death. It was initially used in rubber gardens to control thatch and other weeds, which can make the rubber trees tap rubber one year earlier and increase the production of old rubbe...
