Description of key information
No viscosity data is available for 2,2,3-trimethylbutane. However, data is available for structural analogue isoheptane and is being read across to using an analogue approach. A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
The viscosity of isoheptane is 0.5 - 0.8 mm2/s at 20°C.
Key value for chemical safety assessment
Additional information
No viscosity data is available for 2,2,3-trimethylbutane. However, data is available for structural analogue isoheptane and is being read across to using an analogue approach.A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
The measurement of viscosity of petroleum distillates is covered by method ASTM D445 or DIN 51562. A range of 0.5 to 0.8 mm2/s at 20°C covers all possible grades within this substance description if measured with the agreed method. A test conducted by DHC (2010) according to DIN 51562 demonstrates that measured values fall within this borderline value with 0.792 mm2/s at 20°C.
