Examples
Embodiment 1
[0020] Example 1 20% triclopyr dimethylamine saline solution
[0021] Triclopyr 20%; Dimethylamine 5%; Tallowamine 5%; Polyoxyethylene alkylamine 6%; Deionized water to make up 100%.
[0022] The preparation method is as follows: Dimethylamine is both a salt-forming agent and a pH regulator. First add dimethylamine into deionized water, then gradually add chlorpyrrole under stirring condition, stir while adding, heat up to make clopyroxy acetic acid completely dissolve. Adjust the pH to 6.0. Cool down to 40°C, add surfactant polyoxyethylene alkylamine and tallow amine, stir evenly to obtain 20% triclopyr dimethylamine saline solution.
Embodiment 2
[0023] Example 2 30% triclopyr ethylenediamine saline solution
[0024] Triclosan 30%; ethylenediamine 15%; fatty amine polyoxyethylene ether 6%; polyoxyethylene alkylamine 6%; deionized water to make up 100%.
[0025] The preparation method is: Ethylenediamine is both a salt-forming agent and a pH regulator. First add ethylenediamine into the deionized water, then gradually add chlorpyroxyacetic acid under the condition of stirring, stir while adding, and heat up to make the clopyroxyacetic acid completely dissolve. Adjust the pH to 6.0. Cool down to 40°C, add surfactant fatty amine polyoxyethylene ether, polyoxyethylene alkylamine, stir evenly to obtain 30% chlorpyroxy ethylenediamine saline solution.
Embodiment 3
[0026] Example 3 40% Triclopyr Triisopropanolamine Saline
[0027] Triclopyr 40%; Triisopropanolamine 20%; Fatty amine polyoxyethylene ether 10%; Polyoxyethylene alkylamine 7%; Ethylenediamine 1%, deionized water to make up 100%.
[0028] The preparation method is as follows: firstly add triisopropanolamine into deionized water, then gradually add clopyroxy acetic acid under stirring condition, stir while adding, and heat up to dissolve clopyroxy acetic acid. Adjust the pH to 6.0 with an appropriate amount of pH regulator ethylenediamine. Cool down to 40°C, add surfactant fatty amine polyoxyethylene ether, polyoxyethylene alkylamine, stir evenly to obtain 40% clopyroxytriisopropanolamine saline solution.
