  • accurate, and for the record, EPA, you can take my DCM wash bottle out of my DEAD DEGREASED HANDS

    • Like, so what if we store our tBuLi with other low-flash point flammables? And pyrophoric oxidizers? In the same bin? That's stuck in a block of ice in the 30-year-old freezer because it hasn't ever been de-iced?

      What if the power goes out for a long period of time and the tBuLi goes for a swim? Or we say you have to de-ice the freezer?

      Haha sounds crazy. And, I wouldn't have to do the shitty quench before disposal. Or work on that project anymore.

      Because you're injured or because PI fires you?

      Haha, yeah :)

      Oh, while you're here, does this still smell like DCM? I can't tell if I rotavapped it all off and the NMR tubes all need aqua regia (sorry my b).

      • Aqua regia isn't even that scary. Try pipetting pure bromine while it shoots itself out from constantly evaporating

        That's just bad management and you shouldn't store tBuLi that long anyway because it'll decompose. You shouldn't put it in freezer either

        just put it on high vacuum

        What are you working with that requires aqua regia to clean NMR tubes? I've only had to use piranha once in a decade, while cleaning things that acetone, DCM, and basic ethanol won't touch, and this was just after moving to another lab

    • Look, I'm all for green chemistry, and I'll switch to using safer, more environmentally friendly reagents and solvents the second they are close to the efficacy of the real deal.

      Until then, leave my acetone and heavy-metal catalysts alone!

      • Acetone is rather green (7 in GSK solvent guide), but I for one haven't used heavy metal catalysts in a year, and more if you don't count palladium

    • When I find a solvent on pubchem that has the taste characterized by some mad lad from the 1800s, it makes me want to try it.

      You say THF is spicy water? Now I'm curious. We must confirm this claim.

      I hear ether smells good. We must confirm this claim.

      These fancy new box cutters are safe and cannot cut your hand. We must confirm this claim.
