Subject: ORGLIST Distilling Thionyl Chloride
We got an old damn dark bottle of thionyl chloride and the boss wants me to distill it before we order a new one... The procedure for purification of thionyl chloride as per the bible - Purification of Laboratory Chemicals - is damned involved and will take days.... Has anyone tried just a simple one pass distillation and used that? Likely still contains impurities but good 'enough' for lab work?
