No, the data was never published. I was finishing a paper on controlling
gas flow under Knudsen conditions for ion implanters that was published and
did not have time to continue the experiments. I find it unusual that there
is little information on RP-1 behavior under extreme conditions.

Is that empirical data published? If so, references please! I have
trouble believing that the solid would be stable in vacuum for any length
of time, unless the thermal situation was very unusual.
