Well the heptane was kind of a bonus, it was a mixture of diisopropyl ether, diethyl ether and heptane, car cold-start fluid. I'd usually not bother, but I needed the range of solvents quickly and straight away. Its over the counter, and the only other ingredient is traces of very, very high-boiling lubricant oil that stays behind. Like I said, usually wouldn't bother but I'd have had to wait if I ordered the ether and DIPE. All thats needed is fractional distillation, the diethyl ether come off first, then diisopropyl ether, and finally the heptane. The cylinder lubricant probably wouldn't come off without vacuum. So doing the distillation at atmospheric pressure works fine enough with a water or oil bath. Didn't exactly need the heptane, but won't throw it away.
Got some regular diethyl ether on its own also, though. Will need drying though. Going to use it for an in-situ Birch-Benckeser reduction of PSE. That is to say, immerse the flask in a cryo bath, cool some dried diethyl ether right down to increase solubility, fill flask with appropriate quantity of finely cut up lithium, then gas with dry ammonia, forming Li-bronze in-situ, then introduce PFED in ether solution. Avoids having to condense anhydrous ammonia down to a liquid, and less fumes to deal with. Never done a Birch-B before, but no time like the present. Although still investigating this new bisulfite scheme. Going to try the same with addition of HCl this time also.
What do you mean cheese to cut? mozzarella bites were just...well for macdonalds food they aren't too bad. And I do like the double cheeseburgers, preferably with bacon and extra cheese on them. All that grease and salt and melted cheese and bacon...it just hits a certain spot, no?
