Have a grignard reaction coming up and the easiest carbonyl for me to get is carbon dioxide. But it has to be anhydrous because grignard reactions are water sensitive. So since i am doing a practice run making the anhydrous CO2 i thought i would do a video about it and then when i do the grignard video i can skip over a lot of this information about how to make the CO2 anhydrous
In the illustrious words of Vinny Boberino..........UP YOUR NOSE WITH A RUBBER HOSE,,,,,,,,It is going to take a while to finish my cellulose nitrate ester video so in the mean time i got a couple easy videos like this one. I only go over the 2 main types of hoses used by home chemist although i am sure there are more types. And then i show my soxhlet apparatus in the "extra video" part at the end
Please do not make this if you do not know what you are doing. And if you do then do it at your own risk. Storing this product is EXTREMELY DANGEROUS because even if you do everything right it still may under go SPONTANEOUS COMBUSTION AND EXPLODE. We are just making an ester between nitric acid and the POLY alcohol called cellulose. Sulfuric acid catalyst is needed to form nitronium ions. Very important to do at 0 C. Part ONE is the paper work, Also i make 70% nitric acid and then make nitronium ions from that. Part TWO i will nitrate some cellulose with the nitronium ions i made in part ONE AND THEN start cleaning/neutralizing the gun cotton ..............PART 3 i will finish cleaning (neutralize) the gun cotton and talk about storing it
Sorry about the audio at the end. But if you turn the audio all the way up you will hear me talk. Please do not make this if you do not know what you are doing.

When i improve a method of synthesizing a compound from the method in one of my videos i will post the new method in the description under that specific video..... AND,,,,,,,, on my "discussion page" at https://www.youtube.com/channel/UCu6JpDaLoyLvkPnETLpO_YQ/discussion?disable_polymer=1 or https://www.youtube.com/channel/UCRlRakXX0hacAXBzen1dZcg/discussion ...........ALSO........Lately i have been adding easter eggs/extra video to some of my videos at the end of the video. Giving lab tips or just showing some of my equipment or showing some chemical that looks cool like maybe some crystals or something..............THE COVER PIC IS 240 mL OF FUMING RED NITRIC ACID
Bitchute does not really have playlist but my channel on youtube does. So if you are trying to learn a specific functional group like alcohols or nitro alkanes or alkenes etc... i have about 40 or 50 playlist at https://www.youtube.com/channel/UCu6JpDaLoyLvkPnETLpO_YQ/playlists?disable_polymer=1 ........ALSO.......If you like music i have a playlist labeled "GOOD MUSIC" that has a hundred or so good songs
This procedure should easily get 34 to 36 % by wt HCl acid. Getting 37 to 38% really takes a LOT of waste and time because the rate of HCl gas you pump in to the water is only slightly faster than the release of HCl ...........so it takes forever. Getting a higher percentage of HCl in water will take higher pressures than the atmosphere can supply. Seriously though anything 32.5% or better is GREAT AND SUFFICIENT FOR MOST EXPERIMENTS...............................Well i took the 2nd suckback trap that had 250 mL of water in it. Remember there were no tubes leading in to the water. So anyways i put it in the freezer for a while and some ice formed. I filter the ice out and got 70 mL of 10% HCl acid.
I show how to synthesize concentrated hydrochloric acid from drain cleaner and table salt. Clean and clear as water.....well except for the HCl that is in there. Most of "part 1" is the paper work or math. Then i start the experiment. Part 2 i will finish the experiment.
This was just a way to use my iodine waste when i cleaned my iodine in the last video. HOWEVER IT DID NOT WORK TO GOOD. This was a failure because i tried to make some iodoform (the iodine anolog to chloroform) via the haloform reaction. But i could not make any iodoform (tri iodomethane). Maybe i made the iodine bleach toooooo basic. Or maybe some impurities from the original iodine was in there and screwed things up. Or maybe i used to much acetone and the tri iodomethane (iodoform) is some what soluble in the acetone/water mixture. Maybe a combo of all. I really do not know. But i did learn this. Next time i will use stoichiometric amounts to make it the way u are supposed to make it and not just to try to use the waste from cleaning iodine in a constructive way........................Well i filtered out the crap in the supposed iodine bleach i made. AND I SEE THE PROBLEM................There was no iodine in there at all. I believe the discolor was just contamination from the providone the iodine was extracted from. Even the frit filter i put in aqueous NaOH at the beginning of the video was stained at the bottom with an orange/brown color like providone extract. I think i pretty much got all the iodine out of the frit funnel so there was no iodine in any thing
ATTN: THERE IS A MISTAKE IN THE STOICHIOMETRY IN THE EQUATION AT THE END OF THE VIDEO.....IT IS Cl2 +2NaOH >>>> NaClO + NaCl + H2O and not Cl2 + 4NaOH >>>> 2NaClO + 2NaCl +2H2O............Same with iodine...........it should be I2 + 2NaOH >>>> NaIO + NaI + H2O..................... OXYACID NOMENCLATURE............Just some misc stuff showing some patterns in oxyacid nomenclature and etc...
Finally going to test that toluic acid (carboxy methylbenzene) i made in a previous video. I should have recrystallized the toluic acid so i got a more accurate "actual yield". Admittedly i got a bad yield here but it is not the reaction. I should have got at least 70%. But the toluic acid was not pure to begin with. The amounts i was working with were small which usually yields a lower yield than usual. Plus i stopped the decarboxylation early cause it was making me paranoid that the can may leak and catch on fire.....etc etc................I did realize it is probably better to use the salt of the acid to start with. So in this case sodium toluate..........if it was benzoic acid then sodium benzoate would be better to start with.........BECAUSE the whole reason to put NaOH and the acid together is to make the salt anyways. That way you know you got a 100% conversion of the acid to the "salt of the acid"...........In the video above the NaOH has to find the toluic acid to make it the salt of toluic acid............SO WHY NOT JUST START OFF WITH THE "SALT OF THE ACID"
More females should get in to the sciences. This stuff is not free but 5 or 6 times cheaper probably. This is just another way companies rip women off in the beauty industry. A gallon of acetone cost $12 in a hardware store but.......... a pint cost $6 .........or a liter for $13 for women cause they change the label saying "nail polish remover".
The Jasco acetone can be used just out of the can. If you need it dry then throw some anhydrous MgSO4 or CaCl2 or 3A molecular sieves to dry them. If you wanted it ultra pure then distill it with a vigorex column and discard the first few mL and the last few.............The startex acetone i never used but it could be any where from 90 to 100 % acetone so you will have to distill it to make sure
Part 2 is about the isolation and purification of the ammonium chloride I got a very bad yield but being the first time i did it and having to figure things out and deal with the camera i think it was ok. I could definitely do better on a second attempt with no cam..........I am GUESSING I could get an 85 or 90% yield or better............IT IS DEFINITELY PURE SINCE THE CALCIUM SULFATE WAS NOT ABLE TO PRECIP OUT IN COLD WATER
Part 1 is about how to make and extract the calcium sulfate. It is an interesting way to make 2 salts at one time. Your yield if you don't have to deal with a camera should be very high (98 to 99%). But i did not collect the CaSO4 in the filters that i used after the first collection. All those tiny amounts add up and i got a 90% yield
DID GET SOME GREAT CRYSTALS BUT I COULD NOT REALLY DRY THEM WITHOUT THEM MELTING IN TO THEIR HYDRATE AND THEN DECOMPOSING. IT ABSORBS WATER FROM THE AIR SO FAST IT CAN NOT BE DRIED UNDER NORMAL PROCEDURES. i ONLY GOT A 50% YIELD BUT MOST OF THAT WAS DUE TO ME TRYING TO DRY THE SALT. NOT SO IT WAS ANHYDROUS BUT JUST SO TO THE TOUCH IT WAS DRY BUT IF I USED HEAT THE CACL2 JUST DECOMPOSED AND EVAPORATED WITH THE HYDRATE AND IF I USED NO HEAT THE CACL2 WOULD ABSORB WATER FROM THE AIR FASTER THAT IT WOULD DRY
Great precursor to benzene. Then i got a nice clean/empty ring to put stuff on. Or just add stuff to benzoic acid. Plus benzene is a great solvent..............The benzoic acid crystals formed are VERY UNIQUE. Needle like and very silky smooth. The crystals glide over one another. You will not forget these crystals once you see them

JUST OF VLOG OF THE EXPERIMENTS I DO OR LEARN ABOUT. I LOVE TALKING ABOUT CHEMISTRY SO IF ANYONE HAS ANY QUESTIONS PLEASE ASK. I WOULD LIKE THIS CHANNEL TO BE ABOUT PEOPLE LEARNING CHEMISTRY AND SHARING WITH EACH OTHER WHAT THEY LEARN OR JUST DEBATE ABOUT DIFFERENT REACTIONS. ALL ARE WELCOME IF THEY LIKE CHEMISTRY. PLEASE PLEASE PLEASE DO NOT LEAVE NEGATIVE COMMENTS OR START FIGHTS.
