Recycling DCM
« on: March 19, 2014, 05:17:42 PM »
If you were to do a large scale swern oxidation and there was dimethyl sulfide left in the solvent.  How would you remove it? 

Oxidize it and then remove by fractional distillation?
If you're not part of the solution, then you're part of the precipitate

For a large scale Swern you use a long chain sulphide. This reduces the smell because it's not so volatile. Then you can recover the solvent.
But solvent recovery is expensive unless you are using tons per day, on your scale it's not worth the effort.
I can't remember the exact sulphide but it's around C10.
Development Chemists do it on Scale, Research Chemists just do it!
