I don't get why it's so hard to find these chemistry channels but I'm glad I'm finally here :D

I died laughing when you tried to put out that hydrogen flame😂

GREAT VIDEO........Glad you are still making videos

5:34 : Ah, rubber gloves and open flames... Who doesn't love molten, burning plastic on their skin? (Good to see you back though. Nice Pd crystals on that etched ingot!)

I prefer not touching the flame, with or without gloves

Yeah, I wasn't being too smart there... After that clip I realized how stupid I was, took the gloves off and just used my bare hands :)

Burning plastic on the skin does hurt pretty bad. Lol. I actually lost 50% of the skin on my right hand due to that in August of 2019.

Nice vid, I look forward to seeing your pyridine-whatever reductions. What does your hydrogenator setup look like?

About damn time you upload lol

Great job Tom!

Tom's lab............ I learn something new every time i watch one of your videos. I was wandering why you used KOH to make formaldehyde. I always just used heat. I looked it up and did not know you could use hydroxide to help depolymerize paraformaldehyde. Since you were adding some NaOH right after then why not. GREAT VIDEO by the way

Great channel

I think that every student of Organic Chemistry should learn how simple it is to do this procedure properly. Another Catalyst that would be useful is Adams' catalyst, or simply the Platinum Dioxide that has not been reduced to Platinum Black, but is reduced in situ with the reactants and Hydrogen.

Yo Tom I enjoy watching your vids and if you plan on making anymore it would be neat if you added some background audio music of some sorts. Just thought it might be doable 👍🏻

Good job bro :)

HE'S BACK

can you do a video on making paladium chloride?

It appears he has returned Intelligence 100

Use Aqua Regia in the proper ratio to dissolve Palladium and then boil off the excess Nitric, then add extra HCL and boil to dryness to get your Chloride product.

I did your procedure, but with a palladium extracted from magnetic ceramic capacitors, russian palladium potentiometers and DMG extraction. After reducing that to palladium black I repeated your procedure. I have a question for you - in the end I really got off most of the colour but some green cololouring of the liqud remeined, as well as somefloating white cloudy particles, for wich I think may be due to copper contamination. Any ideas if what I did is ok or not? Any ideas? Now I'm drying the carbon (about 4 gram/5% in my rough callculations..). So I will be able to test it the next days. But I will welcome any coments on what I did. Great video and chanel! Keep going mate!

Love the video. Although I’m curious what form is the Pd in when the KOH sol is added to precip? Is this just elemental Pd or an intermediate? This is an excellent video, thank you👍🏻

I'm not exactly sure, but it was likely some potassium-palladium salt. The exact nature wasn't important to me because I was just trying to get a nitrate-free palladium solution.

It was great, I was looking for such a tutorial, but I did not find anything on KZread, if possible, put platinum emulsions on activated carbon. Thank you

Nice video

if you wanna filter very fine particles through a glad filter and you're not interested in the product in the filter, out a little bit of celite in the glass frit and the filter your solution this should prevent the glass frit from clogging, and even holds back very fine lithium chloride can you provide a link for the paper you used, I would be very interested, thx

Haven’t seen you in while you look a lot smarter already 😂

I prepared the palladium catalyst this way. But over time, the catalyst becomes inactive. Can you guide me?

How can I make Pd/C 10 % ???

tommmmyyyy

When you made benzaldehyde with nitric acid, did you use fuming or azeotropic acid?

@TomsLab

5 жыл бұрын

It was azeotropic nitric acid, 68%.

What does: It was let to "dry over" CaCl2 mean?

@cvspvr

Жыл бұрын

dry means to remove water. cacl2 absorbs water

Pyridin can be reduced with palladium and formic acid. No hydrogen is needed.

How do I scale to 10% Palladium Carbon?

I’d love to see your catalyst’s performance placed against the performance of one made by a reputable company!

@@TomsLab ............You should have put the metal chunk of palladium in the hydrogen flow to see that it does not ignite......i am guessing. But i wander what the temperature differential would have been. Cause i think the metal would have heated up a lot. What if you kept the metal chunk in the hydrogen flow for an hour. I have a gram chunk of palladium. Now i am curious. I bought a cornelus keg to do hydrogenations in

why wash the carbon with nitric acid?
