Made a large bottle of walnut ink with the kids, finally got around to boiling down the seaweed extract I made in the summer to isolate iodine from, made new labels for chemicals I prepared recently, recrystallised a batch of barium nitrate, fixed the ball mill, and spend a lot of time with a GC-MS analysing e-cigarette vapour.

Nice rig zts.
Excellent chemistry there arkoma.

Still away from home.
Today was coke and mentos to entertain the kids, followed by the best vinegar/baking soda I have ever done. Then was some NaOH drain cleaner and a chopped up soft drink can in a wine bottle to produce a lovely buoyant H2 balloon..




A little shameless self-promotion: You are welcome to tour my newly-completed lab.

I recovered some 2-Propanol from a failed reaction today. Distilled it over then salted out the water azeotrope and separated. Tomorrow I will distill it over again to remove any salt and I should be left with some >99% 2-Propanol.

Yesterday discovered that I seem to have an allergic reaction that causes red blotches on the side of my face,
when exposed to some combination of H2O, NaOH, Na2O and Na droplets :(
stupid + lucky = OK now but rather embarrassed :mad:
also lost my nice big clear rectangular pyrex bowl in the explosion :mad: :mad:

Tidied up my gold refining residues, now down to wet sediment in a weighed tube ... and WASHED glassware :D
When dry and weighed I will attempt to dissolve the gold in a stoichiometric volume of aqua regia for another round of purification.
Learning about physical losses of reagents :(

Warmed up a flask containing a lump of tin plus a stoichiometric volume of 36% HCl to give a 'boost' to the reaction.
(so far 3 weeks in my cold shed) This time I hope for near neutral SnCl2.
(previously I used tin shavings in excess boiling HCl ... very quick and works to detect Au+ ions)

Did a quick check for corrosion/evaporation etc. for acids, bases, solvents, reagents etc.
... all OK except for some sodium under baby oil, hence the beginning of my post.
(down to my last 500 ml bottle of 69% HNO3 :(

EDIT: Update ... nett yield = 0.83 g Au powder, GBP19.30 IF 99.99% at todays prices ... financially a definite loss but I'm glad that I did it.

After 'working' with NOx and SO2 I am considering joining the fume hood owners clan.

Brain&Force happened to be in Texas, so we met up and he's staying with me for a couple days. Last night we stayed up until 1 AM doing chemistry. He brought his lanthanides of course, so we played with those a bit, and got to exchange some element samples. We also finished the hydrazine sulfate synthesis that I started a couple days ago, made a couple esters, and experimented with the two dyes that Oscilllator included in my Secret Santa gift (they're really cool, I'll post pictures later). Today we're going to try luminol now that I have everything needed for it, and I'm not sure what else. We're both having a great time though!

Some seeds got planted, and more plastic tubing got holes drilled in it before being mounted on a makeshift, yet sufficiently sturdy bamboo frame.

Meanwhile, back in the shed, half a kilo of ammonium sulphate was quietly recrystallising ...

I love this thread.

Let's see, last night I distilled my isopropanol over NaCl to get good 91% then distilled some H2O because our city water sucks. Been working on "basic" techniques also like holding a flask stopper between my fingers while pouring fluids rather than setting it down.

Bother !


whilst chemically re-re-refining my tiny gold sample recovered from CPUs etc
I accidentally squirted SnCl2 solution into the gold containing test tube, instead of dH2O (couldn't find the emiticon for 'pissed with ones self')

Feels like I'm playing 'Snakes & Ladders' :(:mad:

Oh well, at least it's only tin, shouldn't be to hard to start over .....

Today I SPENT HOURS recrystallizing my "crude, dark, K2CO3" and distilling off what I euphemistically refer to as "Rectified Spirit" <
Not quite sure what my other nine doppelgangers were up to though.

Wow reading all of these activities from other members, I feel like a total fiend for energetics.

Lets see, so in the last week I did a Picric Acid run, about 10g product but more than enough for me.

Did a batch of Hydrazine Sulfate, 57% yield (that's really good for me), total product is about 34g.

I made a little furnace, so that I can make Calcium Cyanamide, but even though it is definitely hot enough, the two batches I've tried friday and saturday didn't work (fucking pissed about that).

Spent awhile just lurking on youtube, re watching Extractions&Ire/ Chem Player videos.

Finally, made some Calcium Oxide from shells in the furnace.

EDIT: Also extracted some Polyisobutylene from some rat/mouse glue traps.

After two messy trials, I think I made a crude amount of manganese(II) oxalate from some MnO2 I extracted from two dead D batteries:

I'm on a chlorinated solvents binge. I distilled some dichloromethane from paint stripper, and then distilled tetrachloroethylene from brake cleaner. I am gearing up to further chlorinate the tetrachloroethylene to hexachloroethane. I also tried to hydrolyze trichloroethylene to chloroacetic acid by refluxing with H2SO4, but failed. I think it needs to be under pressure for increased temperature.

I am also working on a homemade muffle furnace that has been designed to reach 1200°C. The firebrick arrived from Morgan Thermal Ceramics yesterday and I picked up all the hardware at Home Depot.

@velzee--pretty stuff there.

@hawkguy--have a bag of oyster shell calcium for my chickens, some of which I intend to divert into CaO.

@praxichys--I have a pile of 20 or 30 firebrick in my backyard (came with the house). Oh the possibilities...

Finally, I digested some of the oyster shells in HCl, and OMG is CaCl2 hygroscopic. Humidity here has been way low and it still turns to slush in minutes.

Were the firebricks outside? I'm trying to build a better arc furnace from older heat bricks, and it honestly sucks shit, some problem with the bricks. I'd recommend just buying some new ones. As well, a cool thing to do would be to use your CaO to make Sodium Hydroxide, something not many of us have managed to do cheaply or well.

If one were to go about such an extraction, would one simply grind the ashes and charcoal up and wash them? What of the filtrate?

That's good to have on hand if you're working with elemental bromine.
