I have encountered the same problem as you. Using methylamine hydrochloride and sodium hydroxide also requires heating, and the color changes from green to yellow. Did you synthesize iodone by yourself? Did you finally synthesize 4-MMC successfully?

Did you synthesize 4-MMC with methylamine hydrochloride?

Add NaOH, so that there is NaCl in the mixture. It is not a pure aqueous solution of methylamine, does it affect the reaction?

Excuse me, how to make

What should I do if there is only methylamine hydrochloride and no 40% methylamine aqueous solution?

Is it because the unreacted CBD reacted with lye and turned purple?

Alas, keeps failing.

Ask you where the problem lies? CBD99%

Ethanol, acetic acid, and CBD were reacted for 9 hours, and a golden yellow solution was obtained during the reaction. Later, NaOH solution was added to remove the acetic acid, but no stratification was obtained and it turned into a purple mixed solution. What's the matter?

Sir, can HFIP replace nitromethane?

Can AlCI3 aluminum chloride replace nitromethane? Can't buy nitromethane.

Does CBD have to isomerize THC with 95% ethanol? Can I use 99.9% ethanol? What is the pH adjusted to with glacial acetic acid?How many hours does the reflux have the highest 9-THC yield?

Can it be used as a solvent?

Absolute ethanol

steps i changed 1. Add 25% sodium hydroxide directly to the whole material 2. Instead of crystallizing with acetone, directly add 85% phosphoric acid to the upper oil layer. How much does this change affect this route?

The precipitated salt is dried and used without medicinal effect. I couldn't dissolve the precipitated salt with 15% NaOH, the salt settled on the bottom with a small amount of yellow oil on top.

After the reaction, the temperature was lowered to room temperature, and I poured 25% sodium hydroxide solution directly into the whole material and stirred. Stand still and divide into take the oily layer, then add 85% phosphoric acid directly to the oily layer. The pH value is adjusted to 6...

I request to purchase CAS705-60-2. I bought two barrels, which have changed color after being stored for a long time, and the discolored raw materials were recrystallized with absolute ethanol to restore their original appearance. The merchant clearly stated that they are CAS705-60-2. I...

thank you very much

I don't know how to use it. I swallowed 0.5g and inhaled a bit through my nose, nothing works
