I was searching about the boiling point of some material at a pressure of 550 psig
but I could not find any ???
so can any one help me by any reference or fromula to caculate and I will be thankfull

Hope you find this helpful.
I was thinking of using Antoinne's Equation which comes in the form of:
lg P = A - B/(T + C) where
P: Saturated Vapour Pressure of the substance (usually in mmHg)
A, B, C: Antoinne's constants which are specific to the substance.
T: the boiling point (usually in oC)
The values of A, B and C are tabulated in many data books.
You should be able to find the values of A,B and C at the links I had supplemented you or the infamous CRC Handbook for Physics and Chemistry.
