- Conc. based on:
- test mat.
- Incubation duration:
- 4 h
- Temp.:
- 20 °C
- pH:
- >= 6 - <= 7
- Details on results:
- Method: Near the solubility limit several solutions with various concentrations are prepared by the addition of the substance to 25 g water. Each solution is stirred for at least 4 hours and then the viscosity is visually estimated. This was used as a measure for the solubility limit of the substance. The solubility is calculated from the two weights where the transition from viscous to pasty can be observed.
- Conclusions:
- The substance Benzenesulfonic acid, 4-C15-16-sec-alkyl derivs. MIPA salt is soluble at 20°C.
- Executive summary:
The water solubility of Benzenesulfonic acid, 4 -C15 -16 -sec-alkyl derivs. MIPA salt was measured to be 187 g/l at 20°C.
