The difference between 30% glyphosate and 41% isopropylamine salt

According to chemical classification, glyphosate isopropylamine salt, glyphosate ammonium salt, glyphosate plant source, quaternary ammonium salt and organic phosphorus.

The way of existence is also different, 41% isopropylamine salt = 30.5% glyphosate = 33.5% glyphosate ammonium salt = 37.5% glyphosate potassium salt = 34.5% glyphosate sodium salt

In the herbicidal effect, the potassium salt is slightly larger than the isopropylamine salt, and the isopropylamine salt is slightly larger than the ammonium salt and the sodium salt.

Glyphosate is insoluble in water, its salt is easily soluble in water, and the salt may have potassium salt, sodium salt, ammonium salt, isopropylamine salt and the like. Glyphosate is glyphosate acid, which is acidic and has poor water solubility. It needs to form a salt and increase its water solubility. It is generally ammonium and isopropylamine salt, potassium salt, sodium salt, etc. The most common ones are ammonium salts and isopropylamine salts. 41% of isopropylamine salt, 33% of the ammonium salt content of glyphosate is 30%, 41% of isopropylamine salt needs to be configured with the original drug, and now 30% of the market standard glyphosate is not salt.

The calculation formula in the enterprise standard: glyphosate isopropylamine salt = 1.349 * glyphosate content, this formula must first determine that the salt is glyphosate isopropylamine salt, and no other form of salt, this calculation method is barely established, but This is not the case in the enterprise standard, that is to say, 30% glyphosate water, no matter what salt, can be said to be 41% glyphosate isopropylamine saline.

The 41% glyphosate isopropylamine salt solution does not actually need to be developed, and GB 20684-2006 glyphosate water is used. Because it clearly written "This standard applies to glyphosate or a glyphosate water soluble salt of glyphosate, and the composition of a suitable auxiliaries." The molecular weight of glyphosate is 169.07, and the molecular weight of glyphosate isopropylamine salt is 228.2, so the 41% glyphosate isopropylamine salt solution is actually 30.38% glyphosate water (the number after the decimal point is 30% grass) Glyphosate water). The active ingredient is glyphosate.
