PMIDA and Glyphosate is the same pesticide product? PMIDA and Glyphosate What's the difference? In fact PMIDA just a glyphosate intermediate, under certain conditions, can achieve the transformation, following on follow pesticide Let's take a look at the small series of the net .
Glyphosate (PMIDA), chemical name is N-(phosphonomethyl)iminodiacetic acid, the molecular formula is C5H10NO7P, pure product, industrial products are white crystal melting point 210 ° C (decomposition) slightly soluble in water, insoluble in ethanol, An organic solvent such as acetone, ether or benzene. It can form salts with alkalis and amines. It is the main raw material for the production of broad-spectrum germicidal post-emergence herbicides, and an important intermediate in the pesticide , pharmaceutical, rubber, electroplating and dye industries.
If the glyphosate is mixed with water, the reaction is heated with excess hydrogen peroxide in the presence of equimolar sulfuric acid to obtain glyphosate in a yield of 90% to 95%. Glyphosate is a non-selective, residue-free herbicide that is very effective for perennial root weeds and is widely used in rubber, mulberry, tea, orchard and sugar cane fields. As a herbicide, it mainly inhibits the enol acetone-based valerin phosphate synthase in the object, thereby inhibiting the conversion of valerin to phenylalanine, tyrosine and tryptophan, causing the synthesis of proteins to interfere with plant death. . Glyphosate is absorbed by stems and leaves and transmitted to various parts of plants. It can control more than 40 families of monocotyledons and dicotyledons, annual and perennial, herbs and shrubs. Glyphosate quickly loses its activity when it is combined with metal ions such as iron and aluminum, and has no adverse effects on the seeds and soil microorganisms in the soil.
