Results and discussion
Viscosity
- Temp.:
- 20°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 3 416
Applicant's summary and conclusion
- Conclusions:
- The viscosity of the test material was found to be 3416 mPa.s at 20°C
- Executive summary:
This study was conducted to determine the viscosity of the test substance Trihexyltetradecylphosphonium chloride by rheometer DHR-3 with parallel plate system. The sample was found to be shear thinning at higher shear rates at 20°C and hence a zero shear viscosity was calculated by fitting Cross model. The viscosity of the test material was found to be 3416 mPa.s at 20°C
