I would like to ask how to find the specific heats and enthalpies of organic substances in energy balance calculations Such as pentaerythritol and the like! I searched for a long time but couldn’t find it! Hope to get some help! Thank you.
It is available in the \"Handbook of Physical Properties of Chemicals and Materials\"
What the guy above said is correct; you can also check the \"Solvent Handbook\". There is a website that provides some commonly used data: http://www.chemyq.com/xz.htm. There are many useful things there as well – take a look: http://bbs.hcbbs.com/thread-398714-1-2.html. This post was last edited by Flyupwards86 on 2009-3-10 at 12:56
The molecular formula can be drawn using ChemDraw, and an automatic estimation will be provided
I’m currently learning ChemOffice, and I found that it can also be used to look up the physical properties of compounds. Additionally, if one has Aspen Plus or Pro/II, it’s also very convenient for checking such properties
You can also program it yourself and use the UNIFAC model for calculations, which yields quite accurate results as well.
