What are your more memorable chemical experiments? Reactions you won't soon forget...
Chemical fragrance:
I did once a reaction in a heated sealed steel autoclave containing, among others, DMSO (CH
3SOCH
3).
I realised afterwards that during the reaction half of the DMSO reduced into DMS (CH
3SCH
3).
When I opened the autoclave, a terrible stench overflowed the lab and corridors. It smelled for nearly a week despite all windows opened and fumehoods working...
Of all reactions I did, that's the one I am never going repeat!!!
