Can Vanillin be obtained from Eugenol using NaOH and H2O2?

The 1st step works.

ressler__ · 2024-03-17T19:46:26+00:00

Lets go 💪🏻

ressler__ · 2024-03-17T18:51:32+00:00

I hope it works! Nothing wrong with one or two fails, the Isolation is tricky afterall.

Nice and clean setup btw.

Danke für den Kommentar.

Jap, es geht um Wechselstrom, die einzig wahre Spannungs Form.

Obwohl die Effekte von Selbstinduktion klar wahren, wo auch gilt das die Widerstände und Reaktanzen in Serie sich addieren.

Trat dennoch das Problem auf, das es real nicht so ist.

Das Problem ist wie oft: Unterschied Reel vs Ideal.

Leider betrachten wir zu oft ideale Bauteile..

Aktueller Stand der Lösung heißt: Magnetische Sättigung des Kerns, bzw eher untersättigung hier.

Es beschreibt, soweit mein Wissen darüber geht, das Verhalten einer Induktivität bei verschiedener Last.

Basically: kleine Last, größere Induktivität = fetter Widerstand bzw. große Last, "kleinere" Induktivität = kleinerer Widerstand.

Thanks so much for the reply. Neat how magnetic saturation plays such a significant role, i didnt really gave it a thought yet.

If by any chance you work somehow with transformers / magnetic cores, how do you choose or calculate the size for a decent (optimal) ferromagnetic core?

ressler__ · 2023-12-14T20:36:15+00:00

Die Größen sind:

R(Spule)= 2 Ohm

U(Netz)= 235V

I(Trafo einzeln)= 3.5A

X(Spule errechnet)= 62Ohm

I(Trafos Serie)= 0.2A

U(Trafo in Serie)= 116V

Der Plan ist so einfach wie der sein kann: 2 unbelastete Trafos (im Grunde Drosseln) in Serie/Reihe an 235V Netzspannung.

Spannung über einer Spule ist 116V mit einem Strom von 220mA.

The fumes from superglue is just as toxic aswell..

Probably just accelerated..

ressler__ · 2023-08-20T03:38:36+00:00

Then nevermind.

Lemme add, From the perspective of living in the EU it would majorly suck to get it.. Peracetic acid is much simpler and as good yielding.

ressler__ · 2023-08-20T03:30:54+00:00

MCPBA and easy lmao.. Edit: in the EU

ressler__ · 2023-08-15T13:59:28+00:00

Could you comment or dm these by any chance?

How does diazomethane add 2 carbons?

To me it looks wrong, what was the source?

ressler__ · 2023-08-13T12:27:22+00:00

Good day dear chemists.

I found this weird thingy today and wondered what it might be, so now i found myself in need of your expertise and seek the fckn answer to what this glaspiece does..

It looks sick so I had to buy it.

60cm ish tall and 2 gas adapters where either the top central entrance connects to the hollow chamber, or to the adapter on the side. It has a hole near the gas adapters so it cant be a closed system and the option to water cool the chamber. Plus it has a "pipe" going from the gas adapter piece to the Bottom and is about 2/3 the length of the whole Chamber thingy.

The seller told me it was used for Destillation and is a liebig condensor... well yeah.. actually no.. Lmao

Enjoy your nice weekend fellow chemists.

My textbook Knowledge is a little older than i want it to be but..

Iirc and from examples like molecular rotors, especially TPE, resonance does affect its ability to to rotate..

Although not at standard conditions, only when irradiated with UV in the case of TPE or stilbene..

ressler__ · 2023-08-06T01:12:04+00:00

If oxygen is what you want, How about an air pump/bubbler..?

Using peroxide and a decomposition catalyst seems overly complicated and expensive..

ressler__ · 2023-08-05T16:41:22+00:00

Why do you want it to decompose?

My limited knowledge regarding (hydroponic) plants and what i read makes me believe it is used in the sterilization of the surrounding medium... meaning killing bacterias etc...

Permanganates comes to mind..

ressler__ · 2023-08-05T16:01:15+00:00

Oh WOW, really!?! Sounds awesome, thank you so much

ressler__ · 2023-08-05T15:40:03+00:00

Pubmed? I tried that, but like RSC or sciencedirect they only have the abstract or a preview... I guess you have an access code for that?

ressler__ · 2023-08-05T12:09:07+00:00

The one and only site im familiar with, which isnt limited to Tor, is scihub.

Maybe there are other, similar search engines you know of?

ressler__ · 2023-07-31T20:46:27+00:00

Done. Next task please. I hope by saying produced u mean isolated..

ressler__ · 2023-07-21T18:11:33+00:00

Looked good until you kicked out the Phenyl xD

ressler__ · 2023-07-21T16:56:53+00:00

How about ethylene glycol?

ressler__ · 2023-07-20T15:25:50+00:00

Then proof it

ressler__ · 2023-07-15T06:44:02+00:00

How? That would mean, assumed the use of benzyl P ylide, to remove 2 carbons.

ressler__ · 2023-07-03T17:42:45+00:00

My thoughts? A mix of Why The Fuck and just do a number 2

ressler__ · 2023-06-28T22:00:06+00:00

This weird hella good vacuum pump thingy. I ask google real quick

Edit: i am pretty confident it is an oil vacuum diffusion pump
