Barium carbonate in uranium extraction The thing about barium carbonate that is critical here is the Ba2+ ions. Any soluble barium salt wo ...	13-9-2022 at 16:16 by: j_sum1
Barium carbonate in uranium extraction I would not have thought of Ba salts as being expensive in this context. And other Ba salts would s ...	13-9-2022 at 14:43 by: j_sum1
Secret Santa You guys are hilarious. Any thoughts on how to make this year even better. May as well get those ...	8-9-2022 at 03:00 by: j_sum1
Secret Santa I am up for it again. It is not too big a task for me and it is a lot of fun. The only thing is, I ...	6-9-2022 at 14:44 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) Hmmm. Should not be any dicyclopentadiene after treating with permanganate. Certainly not enough to ...	4-9-2022 at 13:35 by: j_sum1
Acetic acid yellow/brown colour. What is the source of your bisulfate? If it is pool grade, it can be pretty dirty.	4-9-2022 at 03:26 by: j_sum1
Making Iron from Sand Cast Iron has a carbon content of typically 4.3% by mass. That is the eutectic point of the carbon ...	3-9-2022 at 20:10 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) I was prepared to consider the effect of residual MnO2 particles acting as a catalyst. They could h ...	3-9-2022 at 19:54 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) Ok. Mystery solved. I am not going crazy. The most likely explanation is that the thermocouple ...	3-9-2022 at 19:51 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) Tested with KMnO4. No reaction at room temp. Oxidised with some difficulty in Bunsen flame. But the ...	3-9-2022 at 18:31 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) Cracking was not something I expected. I thought some kind of catalyst and a higher temperature wou ...	3-9-2022 at 04:52 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) [rquote=676383&tid=158863&author=Rainwater]Might be a secondary reaction. You can confirm ...	3-9-2022 at 04:43 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) Yeah. That was my first thought. But with such a large last fraction, such a high distillation rate, ...	3-9-2022 at 01:18 by: j_sum1
Distillation tails at lower temperature. (Damn. I thought I fully understood distillation.) See thread title. I have been distilling solvents recently to obtain some fractions that are clea ...	2-9-2022 at 23:50 by: j_sum1
Disposal of tar and organic waste I am sure that there have been threads that have mentioned this, but I do not see it coming up often ...	2-9-2022 at 20:45 by: j_sum1
Making Iron from Sand Yeah. This guy is good. A lot of skill in mandling clay and other bushcraft techniques. Fundament ...	2-9-2022 at 20:36 by: j_sum1
Naptha for essential oil extraction [rquote=676279&tid=158854&author=PirateDocBrown] j_sum, you'd be surprised how much toluene ...	1-9-2022 at 05:31 by: j_sum1
Naptha for essential oil extraction Ethanol will not be suitable in this case because it is miscible in water and the OP is attempting a ...	31-8-2022 at 20:55 by: j_sum1
Naptha for essential oil extraction I distil petrol (gasoline) and collect a suitable fraction for extractions like this. You can also ...	31-8-2022 at 18:33 by: j_sum1
Phenol from Salicylic acid Sounds like a temperature problem. IIRC, Doug's lab has a video on this that is better and clearer ...	30-8-2022 at 20:26 by: j_sum1
James Webb Space Telescope - replaceable mirrors? I am really surprised that they were able to do it at all. The L2 is a feature of the sun-earth sys ...	30-8-2022 at 18:05 by: j_sum1
James Webb Space Telescope - replaceable mirrors? [rquote=676183&tid=158846&author=Texium]Yeah, while Hubble is in low Earth orbit and thus ea ...	29-8-2022 at 19:03 by: j_sum1
Isononyl alcohol While on the topic, ammonium nonanoate is used as a weedkiller: an alternative to glyphosphate. That ...	29-8-2022 at 04:27 by: j_sum1
Myth of Streching Space [rquote=676177&tid=77818&author=Chalo] Needless to say a galaxy is far too hefty a thing to ...	28-8-2022 at 16:06 by: j_sum1
Isononyl alcohol Make some interesting esters?	28-8-2022 at 01:30 by: j_sum1
