Year 2003: Re: ORGLIST:AMINE WORK-UP

Hello,

you will have to use a solvent to make amine soluble and the solvent should be water immiscible like chlorobenzene, ethylene dichloride, toluene, etc. the pH of reaction mass has to be made near to neutral but careful in avoiding precipitation of iron hydroxides, then filter over hyflo type material to remove the slimy solids if present, then separate the layers from filtrate. recover your amine from organic layer.
