Title: 2CT2 Melting Point
Post by: raybeez on January 31, 2003, 02:20:00 PM

Hello,

Was wondering if anyone had any values for the melting point of any 2CT2 salts. Checked Phikal, Merck, UTSFE, etc, and couldn't find mention of it. Any info would help.

Thanks

It is not listed in Beilstein Crossfire either, so your only hope is if it is in SciFinder, or if someone has a sample of their own to test for you.

Hey Rhodium,

If I were to draw the molecule out in ChemDraw, there's some kind of algorythm that it can run to predict the melting point. Do you know how accurate a method this would be?

Anyone else: Let me know if you've ever tested a sample of this before

Thanks

For most organic salts, the decomposition temperature lies below the melting point.

My chemdraw program analyze sez that 4-Ethylthio-2,5-dimethoxy-PEA freebase melting point is 450 K and bp 617 K

...which is obviously nonsense - don't trust those predictions.

It might be little inaccurate but it guessed some bp's with an accuracy of +-5C.Enough for rough guess.

I think it may be very correct when it comes to molecules containing few hydrogen bonds, but for more complex things it will probably wander off in the wrong direction.
