- Executive summary:
Based on the DSC measuremtns over a range of 40°C the melting point of TEPIC-G is 92.8°C
Reference
Three measurements have been made with an average of 92.8°C / 365.9°K and a S.D. = 0.19°C / 0.19 +K
Description of key information
Melting point is 92 - 96 °C at normal pressure
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 365 K
Additional information
Melting point was cited in NICNAS Chemical report (1994) from SDS data of data owner Ciba Geigy Ltd.
The value measured with a particular batch was 92.8°C for TEPIC-G, and 94.6°C for TGIC. Both values are within the range of 92 -96°C published by NICNAS
