I really need help with Ammonia

[Kayra]

I need a chart that shows the boiling point at various pressures. I need to determine how much pressure it will take to liquify it at approx 40 C

 

After page 5 on google i gave up.

 

Anyone out there know of such a critter?

Google

ammonia "phase diagram" 87,000 hits

NH3 "phase diagram" 14,600 hits

CRC Handbook gives equation for vapor pressure vs. temperature below critical point.

 

Thermodynamic Properties of Ammonia

Ask gas suppliers like Matheson and Liquid Carbonic.

Thanks UA

 

"phase diagram" were the magic words I was missing in my search :doh:

 

Those silly NIST guys though.. want to charge for access to thier database...

 

Perhaps when I start to make money from my concepts I might consider that :cup:

UncleAl, I had decided that if I have to use an online dictionary just to read the header to your links ( http://www.mazepath.com/uncleal/ ), the articles would likely have been far beyond me.

 

Fortunately for me, I braved a few anyway and was pleasantly surprised to find I only needed 3-5 trips to google per article :doh:

 

The humor is superb, and the links quite entertaining. Thank you.
