CAS number: 142-90-5
The kinematic viscosity of the test item was measured with a
micro-Ubbelohde viscometer according to DIN 51 562 at 20°C and 40°C as
preferred by the OECD Guideline 114 (“Viscosity of Liquids”).
Kinematic viscosity at 20°C : 3.56 mm²/s
Kinematic viscosity at 40°C : 2.30 mm²/s
No study exists for the viscosity of n-Dodecyl methacrylate.
Read across to the structural analogue individual substance i-Decyl
methacrylate (IDMA) and structural analogue UVCB substance C12 -C16
methacrylate (LIMA, CAS: 90551 -76 -1):
i-Decyl methacrylate: Viscosity: 3.56 mm²/s at 20 °C, OECD 114 no GLP,
experimental data (Liddiard C (2008)
C12 -C16 methacrylate (LIMA): Viscosity: 6.24 mm²/s at 20 °C, OECD 114
no GLP, experimental data (Liddiard C (2008)
Overall, the physicochemical properties of the long chain alkyl
methacrylates (C12 to C22 methacrylates) are showing a regular pattern.
The viscosity is increasing with increasing molecular
weight/volume (i.e. alkyl ester group) within the series.
In analogy of the related UVCB substance LIMA (C12 -C16 methacrylate)
the kinematic viscosity of Dodecylmethacrylate is approximately 6.24
mm²/s at 20 °C. (Liddiard C (2008)).
