What is Thermex ? 1

[JOM]

Can anyone tell me the chemical name or formula of "Thermex", please? There was a release of Theremex gas in the UK from a chemical plant, but no description of what it is or what it is used for. The report said it is an irritant and smell like geraniums.

John.

Thermex is "diphenyl ether". I think it is used as a heat transfer fluid amoung other things. Look for the safety data sheet via a good internet search engine (IPCS will have one).
The odour threshold is very low (about 0.1ppm) and it does smell of geraniums.
