Glypho ( Glyphosate 41% SL )
We are engaged in offering excellent quality Glypho to our valuable clients. Glyphosate 41% SL is a non Selctive Herbicide.
PHYSICAL CHEMISTRY
glyphosate
Composition Tech. is ³95% pure. Zwitterion structure (P. Knuuttila & H. Knuuttila, Acta Chem. Scand., 1979, 33, 623). Mol. wt. 169.1 M.f. C3H8NO5P Form Colourless crystals. M.p. 189.5±0.5 °C B.p. Decomp. >200 °C V.p. 1.31 ´ 10-2 mPa (25 °C) KOW logP <-3.2 (pH 2-5, 20 °C), (OECD 107; EEC A8) Henry <2.1 ´ 10-7 Pa m3 mol-1 S.g./density 1.705 (20 °C) Solubility In water 11.6 g/l (25 ºC). Insoluble in common organic solvents, e.g. acetone, ethanol and xylene. The alkali-metal and amine salts are readily soluble in water. Stability Glyphosate and all its salts are non-volatile, do not photochemically degrade and are stable in air. Glyphosate is stable to hydrolysis at pH 3, 6 and 9 (5-35 °C). pKa 5.77±0.03, 2.18±0.02 (20±2 °C), (OECD 112) F.p. Not flammable
glyphosate-isopropylammonium
Composition As a wet cake, contains c. 62% w/w isopropylamine salt, c. 35% water. Mol. wt. 228.2 M.f. C6H17N2O5P Form Odourless, white powder. M.p. Occurs in 2 steps, 143-164 °C and 189-223 °C B.p. Decomposes without boiling V.p. 2.1 ´ 10-3 mPa (25 °C) KOW logP = -5.4 Henry 4.6 ´ 10-10 Pa m3 mol-1 (25 °C, calc.) S.g./density 1.482 (20 °C) Solubility In water 1050 g/l (25 °C, pH 4.3). In dichloromethane 0.184, methanol 15.88 (both in g/l, 20 °C). pKa 5.77±0.03, 2.18±0.02 (20±2 °C), (OECD 112).
