Glyphosate (PMIDA), chemical name is N-(phosphonomethyl)iminodiacetic acid, the molecular formula is C5H10NO7P, pure and industrial products are white crystals, melting point 210 ° C (decomposition), slightly soluble in water, insoluble In organic solvents such as ethanol, acetone, ether, 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.
Therefore, glyphosate and glyphosate are not the same product. Glyphosate is only an intermediate of glyphosate, which can be converted to glyphosate under certain conditions.
Flame Retardant Coverall is a kind of
Coverall which once leave the fire will be extinguished. It is made of
100% cotton cloth mix with flame retardant fiber. Flame retardant
clothing fabric flame retardant fiber to fiber in the combustion rate
greatly slowed, self extinguishing immediately after the fire away, and
the rapid combustion part carbonization and does not produce melting,
dripping, or piercing, give people time to evacuate combustion of the
scene or take off clothes, reduce or avoid burns, scalds, achieve the
goal of protection.
It is widely used in oil field, petrochemical industry, gas station, chemical industry, fire fighting, etc.
