Haven't just yet, since I'm busy watching star trek on TV, but after TOS and voyager, plus tonight's episode of another, rather retro (understatement of the year, it being shown in color part-way through one of the episodes) show called 'lost in space'
But then I'm going to get myself some new Buchner funnels, of the type that have glass frits and vacuum adapters (the ones I have need vacuum flasks, there are two basic types, one that plugs into a flask that has a side-arm to connect to a vacuum source, the other has the vacuum takeoff built in near the top of the neck, above a ground-glass joint which fits to any kind of flask, and a longer hollow glass stem running through the center of the joint.
I fancy getting myself some more of that type, and especially, something I don't have atm, namely really small ones, 5ml, 10ml, 20/50/100ml, even 1ml if I can find one that small for ultra-microscale work.
Got a bit under half a grand, so after buying a range of different sized fritted buchner funnels, methinks I shall go shopping for some other goodies. Could do with some more dichloromethane and methanol, another 10 liters of each, same of methanol. I'm out of ethanol atm, although I only use it where ethanol is specifically needed rather than a general purpose solvent, since its usually more expensive, particularly when it is of drinkable grade (I.e very pure and clean) because its taxed to fuck wherever the govt can get at it first. Although I get mine at about $20 a liter of 95% ethanol, the remainder being only water, imported from russia and needs only drying of that last 5% water, being quite clean, more than sufficiently to be drinkable, and indeed far better, when diluted to a suitable concentration with another potable liquid, than is even quite pricy and well-made vodka, and tax free)
So could do with some more EtOH too, as I do have a few uses that other alcohols are not suitable for. Might see if I can grab some carbon disulfide as well, as far as solvents go, after that, definitely going to pick up some lithium aluminium hydride, some more iodine since I'm down to my last 1/4kg or so, figure I might as well divvy it up into 100g portions, get some n-propyl alcohol as well, and prepare methyl-, ethyl- propan-1-yl and propan-2-yl iodides for use in alkylations (of the I2 I already have I mean) and then buy a fresh kilo of iodine. Maybe a little more, so as to further my project working on interhalogens and investigating whether interhalogens other than iodine monochloride form the rather perculiar hydrohalic acid which aren't oxyacids, since on hydrolysis with H2O, ICl forms a perculiar hydrohalic acid which contains only hydrogen and three halogen atoms, two of one species and one of the other, I forget which, but either HICl2 or HI2Cl, which is most unusual, since conventional halogens, fluorine, chlorine, bromine, iodine, astatine form, not counting their multiple oxyacids, simple binary hydrohalic acids, of the formula HX where X=a single halogen atom [as far as oxyacids go fluorine being slightly different, forming only the very unstable hypofluorous acid, not sure if it exists itself, as such, but hypofluorite esters exist at least, it doesn't form the myriad of different oxyacids the other halogens do), but that unusual phenomenon shown in the case of iodine monochloride forming that funky-ass hydrohalic acid justifies some further study with iodine trichloride, iodine monobromide, bromine chloride...although I'll skip at least the vast majority of the fluorinated interhalogens, since they both hydrolyze giving hydrogen fluoride, lethal stuff at the best of time. And most of them are even deadlier than fluorine gas, quite capabe of causing concrete to burst into fame on contact with even a low concentration diluted in inert gas. Chlorine trifluoride for example was considered by the axis side during world war II as a chemical weapon but abandoned before it was deployed due to its being too damn dangerous to handle, to the german factory workers meant to produce the stuff and/or store it. It and chlorine pentafluoride are probably the two most dangerous but none of the fluorinated ones are in the least pleasant. Iodine monochloride is, of the interhalogens probably the safest to handle but my first encounter with it left me having to use an inhaler for several days after a chance accident due to a fault in my gas mask that caused a valve to slip and me to get a trace breath, as I noticed a slight change in the smell of the air and ran hell for leather to repair the mask (and stay alive in the process
)
(although ever since then, I've been triply careful in checking, rechecking, adjusting the fit and re-re-checking the fit of my gas mask, and changing the canisters extra-often, way more than required, every few tens of minutes rather than several hours at worst just to be on the safe side, and the several ounces of iodine monochloride has behaved itself, even during distillation to purify it, and since then bottled up in a chemically-resistant bottle with a fluoropolymer cap, fluoropolymer seal under the cap and a heavy wrapping of teflon tape round the screw thread of the bottle neck, the bottle filled with argon and kept in the fridge unless its needed, and never permitted to contact anything but glass and fluoropolymers, needing all-glass syringes with no plastics or metals in the seals, or no seals at all, not even metal needles for transfers, since it is brutally corrosive stuff, disintegrating any but perfluorinated plastics within a quarter to a half hour or so in many cases, sometimes less, and taking maybe 12 hours to a little longer to eat halfway through a stainless steel keck clip; meaning if I used the usual method of transferring hazardous chemicals, via cannulae, the iodine monochloride would attack the needles and contaminate the reagent at best, or burn through them if they were used too many times. The fluorinated interhalogens on the other hand are....well they just aren't anywhere nearly like that friendly, not by a long shot.
