Test Objective

To screen a sample of 3.7.11-trimethyldodecyn-3-ol in order to determine the onset temperature and magnitude of any endothermic or exothennic events when ramped to elevated temperatures.

Test Results

1.Reaction
Onset-temperature	130°C
Peak temperature	153.3°C
Energy release	28 J/g

 

2.Reaction
Onset-temperature	306.8°C
Peak temperature	312°C
Energy release	556 J/g

The sampte was observed to undergo an exothermic event from 119.5°C which had a heat of decornposition of -27 8 J/g. A second exothem was then observed to commence from 208.7°C which had a heat of decornposition or -556.2 J/g. No further significant energelic events were noted up to 500°C.
