OK, well the wick is actually nothing but a piece of filter paper on the wall of the jar you perform the TLC and it must touch the solvent and saturate the atmosphere inside with solvent vapors. this is easy to do. Spots should always be applied with a capillary tube. A nail hardening UV lamp is...

Fundamental aspects of science feel different when they keep account for recent discoveries and the conclusions regarding the influence of new ideas are better presented. I see there are advantages but good writing is exactly the best and older stuff like Vogel's 5'th edition is for a...

Eu am dat instant cadou 3-4g cand am vazut pe altul cum face stiind ca asa faceam si eu, sunt foarte multumit ca m-am lasat si ca ma pot bucura ocazional de pae cu iarba. Ca fapt divers se face prea simplu ca sa nu-l prepari tu si profitul e comparativ absurd de mare, ca si cum compari lumina...

Great job Brain! Keep up the good work and stay as motivated as your essay made me.

Hi, here you can find your way towards making the mephedrone yourself and benefit more. If you want the product someone will offer it to you, but, wether you pay thousands per kg and risk quite a lot or pay hundreds per kg and not worry about the way the stuff gets to you, it's up to you. I can...

The procedure in the link starts with a different substrate than ritalinic acid but just check the comments and you will gain more insight.

Most probably yes, but concentrated sulfuric has much less water in it and esterification is an equilibrium reaction where the water resulting from the reaction of the alcohol with the ritalinic acid also has the power to hydrolize the very same bond. This is conventionally accomplished by using...

You must perform an esterification reaction with methanol, this is usually done with sulfuric acid as catalyst but I trust you will find the preparative writeup around here. If you can get your hands on sulfuric acid you will also be able to make HCl.

I'm still hoping NBS will do, just unfamiliar with it's way of use (no p-Tosyl available unfortunately). All he pool chemicals I saw were chlorine based, I am aware there is a bromine based one too but just concluded it's not within my close reach. Used to have 1L of Br2 and it was the most...

I can't seem to find any otc source of any bromide containing inorganic salt where I am at.

In return of a hint regarding the bromination I can point out the absolutely cheapest and most efficient way to get the styrene that I plan to create a video of.

As a detail, working with dimethyl sulfate is at a level of skill way past the mistake we were talking about... the whole thing is somehow designed for a stuck on an island scenario. Or just fundamental science that only proves that it can be done. This route was a journey that thought me a lot...

There are quite a few of us competent enough to proofread what you understood and calculated from the links provided by master G.Patton, including himself. Start small and understand a lot, equipment improvs and substitutes are applicable to a limited extent therefore ask someone you deem...

It's just not the most efficient way... even though possible, I would personally enjoy the MDA since significant losses are to be expected at the final monomethylation step. MDP2NP can also be converted to MDP2P and then subjected to reductive amination with methylamine but I have no idea about...

This is the first actual multistep synthesis my chemical adventures started with... of course 2,5-dimethoxybenzaldehyde is best obtained commercially and my journey ended with getting hold of 2-hydroxy-5-methoxybenzaldhyde which I learned a very important lesson from (never put all your material...

it's how we learn and implement knowledge... things don't typically work from the first try, having it working but very inefficient is what you are normally getting before exploring the reaction. I feel like I'm willing to give it a try with IPA instead of butanol (aware of the miscibility), I...

you have to hydrolize the ester to the acid and then react with another alcohol to obtain a different ester... transesterification reaction is best and can be done with enzymes (novozyme- CAL) but I dont know a protocol... the easiest way is to get the ritalinic acid

Just don't attempt organometallic chemistry if you are unfamiliar with pyrophoric material handling.

I had this prepared with no inconvenience I can remember of, my means of Al/Hg reduction but can't remember what acid is involved I isolated the actual salt but the salt form is suitable for longer term storage and not needed if you plan to methylate the nitrogen (which I never did).

Confirmed, you must take into account the molarity of the aqueous solution and the water of crystalization which is 5 water molecules per CuSO4 molecule when talking about the blue crystals which are the more common form with a molar mass of 249,28 g/mole including the five moles of water in it...
