To determine the solubility of tosylmethylisocyanide and octadecyl amine in acetonitrile by NMR.
Saturated solutions of tosylmethylisocyanide and octadecyl amine
were made in
acetonitrile. Inorder to saturate the solutions, after the last addition of solute to acetonitrile they were vortexed for 10min each. After centrifuging the vials the supernatants (100uL) were placed into NMR tubes containing 700
Proton NMR of the solutions were obtained on a 500MHz
Varian Unity Inova
The solubility of the isocyanide and the amine was determined using
TOSMIC in AcCN
TOSMIC in AcCN/ DCE
- in CDCl3
Octadecylamine in AcCN
[also routinely get a regular spectrum of new solutes in CDCl3 and upload to ChemSpider JCB]
[can't see how you can count 6H for octadecylamine JCB]
18:00 Madeup a saturated solutions of tosylmethyl isocyanide and octadecyl amine in acetonitrile. After the last addition of the solute each solution was vortexed for 10min to ensure saturation.
19:20 Centrifuged the saturtated solutions...clear supernatants were seen at the top.
19:30 Obtained a picture of the solutions.
19:45 placed CDCl3 (700uL) in to two clean NMR tubes labeled
. Added the supernatant from tosylmethyl isocyanide vial (100uL) to NMR tube
Also added the supernatant from octadecylamine (100uL) to the NMR tube
20:00 Obtained HNMR of the solutions.
20:55 Added 10uL of 1,2-dichloroethane to the NMR tube
containing TOSMIC in acetonitrile. Obtained a HNMR.
