Results      

Preliminary test

From 375°C upwards the weight of the sample decreased significantly. At 428°C the sample weight had decreased by 25%.

 

After the experiment a small brown residue 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 350°C and 475°C an endothermic peak was observed which was due to boiling of the test substance. The extrapolated onset was determined to be 417.15°C.

 

During the second experiment the endothermic boiling peak was observed with an extrapolated onset of 417.44°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 was concluded that the melting temperature is < -20°C (253K).

Conclusions:
The melting temperature of Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane was determined using DSC. The melting temperature of the test substance is < -20°C. The atmospheric pressure was 1017 ± 2 hPa.
