Re: Heat transfer fluid with particular properties: suggestions?

You might have a little problem with the corrosion inhibitors decaying with
time.   Would there be a low temperature silicon oil which would fit this
bill?  Can you pressurize the system to allow for organics such as benzene,
acetone, or perhaps hexane?
