Preliminary test

From 400°C upwards the weight of the sample decreased significantly. At 434°C the sample weight had decreased by 25%. After the experiment a small brown deposit remained in the sample container.

 

Main study

During cooling as well as during heating, no effects were observed which were caused by crystallisation and/or melting. Between 375°C and 500°C an endothermic peak was observed which was due to boiling of the test substance. The extrapolated onset was determined to be 421.59°C.

During the second experiment the endothermic boiling peak was observed with an extrapolated onset of 421.62°C.

Additionally, the test substance was stored overnight in a -20°C freezer in order to determine if crystallization occurs. After storage the test substance had not been crystallized. From this it will be concluded that the melting temperature is < -20°C (253K).

Conclusions:
The melting temperature of Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid was determined using DSC. The melting temperature of the test substance is < -20°C. The atmospheric pressure was 1016 ± 1 hPa.

Description of key information

The melting/freezing point of substance EC# 270-470-1 was determined to be < -20°C

Key value for chemical safety assessment
