Database for chemical and physical properties

[dRic2]

Do you know any website where I can find chemical and physical properties of common substance (heat capacity, enthalpy of formation, boiling point ecc...)?

Thanks

I use and love Pubchem which branches off NCBI if I remember correctly.

This sire might be more what you're looking for:

Mhm I found it earlier, but no. It lacks lot of information like enthalpy of formation and heat capacity.

I used to know an amazing website, but I can't remember its name

In general best databases are behind a paywall.

Of course, but I though properties of common substances (i.e. CO2, K2CO3, H2S, HCL, stuff like that) would be easy to find. Wikipedia has a some nice stuff, but I am looking for a little bit more informations.

That's the website I used to use, thanks!

But I think KHCO3 is not that common after all guess I'll have to go to the library...

That site has a lot of information, just not what you are looking for.
Melting Point: Decomposes before melting

http://www.sciencelab.com/msds.php?msdsId=9927398
All it says is "irritant", "avoid contact", "wear respiratory equipment", and CAS# 298-14-6

http://www.chemicalbook.com/CASEN_298-14-6.htm
Plenty of background info. Melting Point 292C

https://www.scbt.com/scbt/product/potassium-bicarbonate-298-14-6
Their MSDS shows:
Melting: 100C
Boiling: 333.6C
Flash Point: 169.8C
Pay attention to MSDS section 11. TOXICOLOGICAL INFORMATION

Many more if you search on the CAS 298-14-6, just not the info you are looking for.

Good Luck!

exactly. Well, I can't do much about it...
