- Conclusions:
- Solubility at 20°C was determined for IR5878 technical grade orthosulfamuron in the following media
Solvent Solubility at 20°C
n-heptane 0.23 ± 0.01 mg/L
xylene 129.8 ± 8.5 mg/L
acetone 19.5 ± 0.3 g/L
ethyl acetate 3.3 ± 0.1 g/L
1,2-dichloro methane 56.0 ± 2.2 g/L
methanol 8.3 ± 0.4 g/L - Executive summary:
IR5878 is soluble in most common solvents. Only in n-heptane and in xylene the product shows less solubility, with a solubility of roughly 0.2 and 130 mg/L, respectively.
