Does anyone know, or know where I can find info
on the physical and optical properties of ethane
(C2H6) at -178 degrees C and 1.6 atm? It's a liquid
at that temp and pressure.

I need the colour, transparency, reflectivity and ior.
I looked in the newior.inc file, but couldn't find anything.

Thanks

Gail

If you're on school, college, you can ask your Chemistry teacher, he
should have table books, with all that kind of information. The only
think I know by now, is that it will look like water.

or go to your local book store or library and check out the crc handbook
on chemistry.

Maybe if it is newer than the 46th edition...my CRC Handbook of 
Chemistry and Physics had a lot of information on ethane and similar 
compounds, but not the ior.

I think you'll have a hard time finding this information. If you cannot
find it in any of the more common chemistry references, you might have
to go through Chemical Abstracts. For those that don't know of Chem Abs,
it's basically a (massive) index of many chemistry journals, with
listings by author, subject, compound, etc. Any good university science
library will have it.

Thanks. I'll look out for it.

Thanks. I'll look out for it. When was the 46th edition published?

Can't help you there, Gail. If it were ethanol you needed...
especially solved 2:3 in water with some floral extracts, mmm...

Hi Gail.

AFAIK the index of refraction is linked to the density of the
matter. You have to find the density of ethane at the point you
specified and then compared it to the densities and iors you know.
It's an approximation but better then nothing.

Check this:
