4MMC Reagent Kit - First Synthesis (100g Scale)

My question is, since I'm not hunting the pics down, how does one test the pH of DCM? DCM doesn't have a pH. My litmus papers don't work on non-polar solvents. Can you trust a pH reading that isn't in water?

Frit BuchnerEverything has a ph; if its reading neutral then yore a couple drops away from being slightly acidic. You could get away with the ole red cabbage ph paper with the requirements of this synthesis.

I didn't graduate high school in the traditional sense, and obtained my G.E.D. while serving my first out of 3 bids in the joint, cause I too am a little bit off kilter, lol. I am just fascinated by o.chem and like to party so instead of working research and development for some piece of shit pharmaceutical company I chose to go this route. There is a lot I don't know though and many things I overlook until they're pointed out to me so am always looking to learn whatever I can from whoever is willing to teach me.

Johnny_HammersticksHey I respect this guys motivation AND your reasoning isnt far from the most sane thing to say in justification to your reasoning my friend! I too have the interests and reasoning in the same situations! We should be friends and possibly help eachother from time to time pm me.

5. Approximately 175ml of DH2O was added to the previously obtained Meph-Oil (300ml). Stirrer was turned on so that the layers will not seperate
6. ph 5 was reached and the solution was set aside to sepeate layers. The top layer was decanted, the ph of both layers was confirmed.

The procedure in sticky posts by Marvin says to make sure absolutely no water is present in the freebase mixture, otherwise problems with precepitating, even describing to freeze it and seperate the water.

And you just pour 175ml water on it and start acidification ?!

Maybe i'm missing something which is in the "pictures" ?
