2-Methoxynaphthalene from 2-Naphthol

Nice job. Often commercial activated carbon is not activated at all. Another procedure I suggest is in DMSO. Generate naphtolate ion by dissolvin it in DMSO along with potassium carbonate at 40 C, stirring for few hours. Then quickly add methyl iodide in 1.5 equivalent and stopper. Leave at least 24 h, but even more can be required. After, just pour in water, filter and proceed as usual.

Sounds good but MeJ will react with DMSO as well, and you will need more MeJ, which is not that cheap too.

It's important to note for 7:56: having the same melting point is not a true confirmation that your two substances are identical. There is a method of determining of so-called "mixed melting point temperature". Having two substances with the same melting point you mix two small samples mechanically, with a spatula on a glass plate, to make 1:1 solid mixture, rubbing the mixture very carefully. And then you measure the melting point temperature of this fine mixture. If both substances are exactly same (except for optical isomers) then you will have same melting point or intermediate, if the two samples have slightly different M.P. But if the two substances in question are different and the same melting point is just a concidence, then you will see depression of the melting point and mixter will melt at much lower temperature. I successfully applied this ancient method in Moscow State University lab, because of lack of modern analytical equipment in the organic synthesis lab in russia.

To check the purity use TLC. This way you can often discriminate any unreacted starting material and side products.

Love the video. Would love longer videos, keep it up bro!

Very nice! Where i live nerolin is quite cheap, about US$4 for 100g.

This is Amazing! INSTANT SUBSCRIBE🌻 keep it up! Can’t wait to see your channel grow

[@bobsagely812]

Did you use a lab fume hood or home fume hood for dimethyl sulfate? I've always wondered how that stuff is handled

[@Anar10n]

Great video! I've seen references of alkylation with MeHSo4 which is somewhat less bad for you, do you know if it works at all?

[@midwestchem368]

I wonder this as it's less toxic too but I'd imagine it needs more heat and time but is also less efficient but I'd wager that It works

[@alllove1754]

How did yours smell???

[@otkcabral4434]

I am way too high and i have NO idea what is going o n but nice video dude

[@peterolsen9131]

oh man , you work with some toxic things ! and i thought the guy that built a ketene lamp was crazy ...

[@kamilstanisawczyk9813]

I didn't supose that methyl sulphate is so toxic.

[@christopherthumm4348]

I wonder if the thicker charcoal that was accidentally introduced on the last video is a better filter then the activated charcoal powder ?🤔

[@TomatDKProductions]

The video is very good quality :D
