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.

Can't help you there, Gail. If it were ethanol you needed...

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:

Nice. Is there a formula relating ior and density of liquid or should
I just guess?
Thanks

Try to find two fluids with similiar densities, then try to inter- or
extrapolate the values. It will be hard for somebody to prove that
you are wrong :)

1965-1966. My copy is starting to look a bit worn...especially since one
of the dogs got it.
The newer versions might have the ior...it is apparently available on
the web, I think there is a free 7 day trial. It might be worth looking
at. URL: http://www.crcpress.com/
Look under "Web Products" for the Handbook of Chemistry and Physics.

It is. My copy is over 30 years old. :-)
Still, it is newer than my (incomplete) set of Encyclopedia Britannica,
which is from 1959.

Same date as our dictionary at home - mostly alright, but oddities abound.
Masturbation, for example, is classified as "bodily self-abuse".

Try to hold on to that Britannica set. It will be quite a novelty
someday, when people will marvel at an encyclopedia that isn't on some
sort of magnetic or optical storage medium <s>. It's more interesting to
see what *isn't* contained within the text, as technology has yielded a
heckuva lot of changes since 1959.

The dielectric constant also plays a major role in the IOR, since the
IOR is related to the change in the speed of light at the interface
between the two media, and a high dielectric medium slows light more
than a low dielectric medium (I think). So you'd have to take this into
account too ...
Just my ha'penth worth,
Mike Andrews.

Try to look up anything to do with "computers", for example...

Nothing....at least, nothing that I could find. Not even anything on
mechanical computers...though there might be something under Babbage.

I have the 1955 edition of E.B. and for computers the index refers to
"Mathematical Instruments" which leads to "Calculating Machines". This article
has over 8 pages, with photographs, and is a good survey of mechanical
calculators from Babbage through to Remington Rand. There is a reference to the
IBM sequence controlled calculator at Harvard (1946) and says "under the
control of a sequence tape; multiplication and division up to 23 significant
figures are possible" Under the heading "Relay and Electronic Calculators" it
says "The electronic tube which can operate in the order of millionths of a
second naturally recommends itself for high-speed calculators, and many such
units have been built. Many of these developments were undertaken during World
War II, and complete information is not yet available to the public."

So I was just looking in the wrong place...
My copy covers ENIAC, magnetic core memory, magnetic drums, etc. I now
wonder how I missed all this...
