Try this. . . . <a href="http://www.aopis.org/" target="_blank">AOPIS</a> . .. .It'll frighten you! Skydrol, Chevron HiJet and similar fluids are organophosphates. Allegedly hazardous to health and sting your willy if you go to the loo without washing your hands after working with the stuff! (I've assumed you are a bloke!!).. .Once you have clicked onto the link, look under the heading "Oils & Fluids". Then click on to "Skydrol MSDS". MSDS = Material Safety Data Sheet. . .Couldn't find boiling point (but I was skimming through) but flash point is mentioned. Try a search on "Skydrol".. .. .Why do you want to boil it?. . . . <small>[ 29 March 2002, 23:23: Message edited by: Bus429 ]</small>

WHY...
Hi
Thanks for the replies, although I still can't find it!!
Its not for me (why the hellwould I need that), its for a Materials lecturer who is going mad trying to find it. He does lots of work for the F1 racing teams, needs the bp value, but can't say what it is for (top secret apparently). These academics are all rather strange...
Cheers

Perhaps they want to use the crappy stuff 'cos it's supposed to be lighter than 5606 or others. I had thought for years that it didn't burn, but it does!!
However a 747 load is quite a lot lighter than other fluids.

The boiling point of Skydrol can be determined by experimental means, any academic worth his salt knows that!
Put some into a calorimeter, place a temperature measuring device into the fluid and heat with a bunsen burner until the Skydrol boils. By observing the temperature indicated on the thermometer scale when this occurs, the boiling point can be established. Caution should be exercised, as there is evidence from the field that although Skydrol itself is non-flammable, the vapour IS flammable.
Once the boiling point has been established please return to the site and let us know the result - we are all gagging to know now...

Hi
You'll probably find it difficult to find the answer written down. Most of the oil manufacturers will concentrate more on Kinetic Viscosity at various temps and Thermal Stability.
They normally need the oil to pass Thermal Stability checks at 274 deg C for 96 hours so that is a starting point for you!

Oh and another thing. At what pressure do we want the skydrol to be at when it boils? The thought of being scalded by superheated Skydrol vapour is rather scary, I think I'll keep away from that glowing brake for while...

Skydrol will burn in a mist, but it won't explode....unlike 5606 (red dyed petroleum based) That was the reason for Skydrol in the first place; when you get a hyd leak it often is from a pinhole in a hose, then a mist forms. Add one ignition source - and BANG!!!
So, for the safety of airline pax, phosphate ester based fluid (Skydrol) was invented. The military don't worry about such trivialities, and carry on with 5606 or derivatives on most of their aircraft.
The researcher may be after using Skydrol in Formula 1 cars for the same safety reasons, but of course you never know - that lot are worse than Area 51 for security!!

Skydrol LD-4, 500B-4, Chevron Hy-jet 4.
As stated, when you get a hyd leak it often is from a pinhole in a hose, pipe, seal, then a mist forms. Not very pleasent for the Lungs, causes you to Cough and Choke, Eye Irritation, and Irritation of Sensetive Body Parts.
Have been involed with problems where the liquid has been heated by the aircraft braking systems, Breaking down the hydralic fluid into an acid, the residue entering the system and causing system failures.
Another thing to think about, but maybe not so for F1, is this liquid tends to break down plastic based structure and components, if allowed to be in contact for any length of time.
