Chemicals that freeze at less than 60 Kelvin

Albertgauss

Does anyone know of a reference to a list of all known chemicals that freeze at less than 50 K? I know lots of organic molecules do, but I don't know which ones. I also can find the freezing points of all the elements pretty easy, but chemicals are proving more elusive.

Alfa Aesar just released a rather large amount of chemical melting point data the other year as part of an "open access" project. If you Google that, you should be able to find that information - as well as other related data sets that are part of this project.

My recollection is that you are probably best off not holding your breath. If you were looking for something around 100 K, you'd have better luck - silanes and certain conjugated organic chemicals can freeze around that point. Even methane freezes at around 90 K (as memory serves).

If you find anything interesting, though, please share! I'd sincerely love to see what you dig up.

CRC handbook of chemistry could be a good place to look

This is a list of elements, http://www.lenntech.com/periodic-cha...ting-point.htm, but it does not include deuterium, which is about 19 kelvin.
