Description of key information
Melting point for octadecyl methacrylate: 28.7 – 29.7 °C (atmospheric pressure [1013 hPa] assumed) (Shibasaki & Fukuda (1982), published experimental data, reliable)
Melting point for octadecyl methacrylate: 23 – 26 °C (atmospheric pressure [1013 hPa] assumed) (Brandes (2003), published handbook data, reliable)
Melting point for Methacrylic acid ester 17,4: 16 °C at 1013 hPa (reliablity: 1, OECD 102, equivalent to GLP standards, non GLP, Evonik Oil Additives GmbH, 2011)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 28.7 °C
Additional information
The melting point for octadecyl methacrylate: 28.7 – 29.7 °C (reliable experimental handbook data, atmospheric pressure [1013 hPa] assumed, Shibasaki & Fukuda (1982), published) was supported by the MP: 23 - 26 °C (atmospheric pressure [1013 hPa] assumed) (Brandes (2003), reliable published handbook data).
Further the melting point of octadecyl methacrylate is assisted by the long chain methacrylic acid ester 17,4 (mixture of approximately 30% C16-methacrylate and approximately 65 % C18-methacrylate) with a determined melting point for methacrylic acid ester 17,4 of 16 °C at 1013 hPa (reliablity: 1, OECD 102, equivalent to GLP standards, non GLP, Evonik Oil Additives GmbH, 2011).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
