I'm looking for references or dictionaries of boiling points

I'm currently writing an article to post to a journal.

I need to write some boiling points or vapor pressures
of some halides on my article,
so I'm looking for some references or dictionaries
which have those values.

Especially I would like to find those values of
Ti, Ta, Hf, W, Si and Al halides.

I know there are those values in WebElements,
but I hesitate to write URLs in my reference list on my article.
I also know some references are listed in WebElemetns,
but I'm not sure which reference has those values.

Could you help me?
