Does anyone know the freezing points of n-alkanes?
Thread Content
I can’t find the freezing points of normal alkanes at all; does anyone know them?
Normal alkanes are a large class of substances; their molecules can have from a few carbon atoms to several hundred carbon atoms, and they exist in forms ranging from gases to solids. How is it possible for them to have a uniform freezing point?
I’m definitely asking about monomers; for example, the freezing point of hexadecane is 18.2°C, and it’s not possible to determine the values for others.
Check a book on material properties; it’s probably not available online
The problem is that it’s not even mentioned in many books on physical properties.
Yes, n-normal alkanes have the highest freezing points. I don’t have the exact freezing point values for specific alkanes right now; I think I saw them in a book. I’ll go look for it:sleepy:
N-hexadecane 291.31K N-pentadecane 283.07K N-tetradecane 279.01K N-tridecane 267.76K N-dodecane 263.57K N-undecane 247.57K N-decane 243.51K What does the original poster want to do? Do we need to collect so many freezing point data points? It took me a long time to find it.
What books did you use to look it up? Are there any more? Any over 20?
Why are no manufacturers entering the monohydrocarbon project?
Hydrocarbons are mixtures, and it is difficult to separate individual hydrocarbons; those with a small number of carbon atoms are hard to separate, let alone those with more carbon atoms
