(geezmeister: "The post-reaction workup: a cook's summary", Stimulants)(thanks Geez ;D )Remember to base the reaction BEFORE adding DCM, Xylene/Toluene - add first, and then base
I think what kris meant by add first is the base. This is usually done with a diluted Sodium Hydroxide solution, to making the basing not as exothermic as opposed to adding the dry soium hydroxide to water.
The reason naptha is often preferred is because it is not as an aggressive solvent as Xylene or tolly and won't pull back as much garbage. Remember that naptha must be warm to perform well as it is lazy at room temperature. Swim read once where Wareami said that a 50/50 mix of ether and naptha would be the ideal NP.
On the other hand swim wouldn't wash his post reaction fluid without including xylene, tolly or some other "aggresive" solvent. TCE(tetrachlorethylene) is also a great post rxn fluid washer.
