very high temperature oil
(OP)
Does anyone know of a heat transfer fluid that will not vaporize at a temperature of 455 celcius while under a pressure of 3000 psig? I can get to 371 with dow corning 710 oil but this still isnt what I need, also the viscocity is much too high at lower temperatures, I suspect the only thing available is a liquid metal alloy.

Check the NASA tech briefs as they have done a lot or research in this area. There is a lot of work been done under the auspices of the NRC on high temperature heat transfer.
We used a molten salt as a heat transfer medium on some very large reactors. The salt was used to extract heat from the exothermic reaction and generate steam. It was heated electrically to start/maintain and circulated with a pump. This wasn’t primarily my area but if not mistaken they ran at your temperature, 850°F @ atmospheric.
You might look at the processes for manufacture of organic anhydrides/acid by the catalytic oxidation of Butane.
