Melting Point of the Liquids in Chemistry
« on: May 09, 2013, 04:54:07 AM »
Can someone please give a long roll of lists indicating the melting points of the liquids in Chemistry? I am trying to obtain glacial Acetic acid from Coconut vinegar by putting it in the fridge and I found out that it's melting point is lower than water. I want to separate it from water through fractional difference in melting points.

Alas! This is scarce data... You can have a look at the
"Open Notebook Science Melting Points"
for instance there
http://www.sciences.drexel.edu/onsc/databook/meltingpointdatabook.php

Generally speaking: be very wary of published melting points, even in paperbooks. Software exists to predict compound properties, and such software is extremely inaccurate (like 60K error) on melting points, but is commonly used and without a warning.

If a melting point is given with <1K precision, or if isomers are given with the same melting point, it's probably false.
