Tabulating thermodynamic data

(1/3) > >>

Zero_1846:
My boss asked me to tabulate thermodynamic data (Delta H, S and G) of different organic compounds (ethanol, ethylene, butadiene etc.) in the rage from 473K to 673K, but I have absolutely no clue how to obtain this data… Can anyone of you help me? Thanks!

Corribus:
The CRC Handbook and NIST Chemistry Webbook are good places to start. But they may have limited data for wide ranges of temperatures. You can use the assumption that enthalpy and entropy changes are invariant to temperature over small ranges. But for large ranges you may need to seek out dedicated studies in the peer reviewed literature.

Zero_1846:
I found NIST but how can I obtain the data from this page?

Corribus:
You type in the compound or formula you want, then scroll down to where the thermodynamic data is.

And how I’m applying this data to the temperature? My boss wants me to do it in 20 degree steps.
