Hi,

I read on http://www.rhodium.ws/chemistry/meth.workup.html To clean honey is a good thing !

That it s removed contaminant like the PEG

You think that his oneself a good thing?

This method is it really essential?

The general consensus is yes. What you read, I believe is by the Geezmeister. I have yet to read anything of his that was not true. The beauty of the A/B is that while the product is in its hcl form you can wash away the impurities that are soluble in non polar solvents. Then when you convert the product to its freebase form, you can wash away the impurities that are soluble in polar solvents. Thus washing away both of the major types of impurities and leaving only the product.

Of course there's always the other side of the story. Many think it not a good idea, but Swigotta never washes at any stage of the A/B. He dilutes, filters, bases, pulls and titrates. Thats the extent of his post reaction workup.

Now, if you were to smoke the crystals that he scrapes up off the plate, you would be in for one more hell of a suprise. You see, Swigotta believes in the recrystallization when it comes to purification of the meth. He is so anal about loss, that he just can't get used to mixing solvents in 4, 5, or 9 times and then throwing it away, confident that there is no product in those rinses. Every time he actually tested to see if there was anything in the rinse, he found residue of garbage and nothing else.

BUT

he still doesn't do it because for him there is no need. All of the junk will be rewmoved in the first dual solvent if its a good clean run. Two if it had a few problems along the way and three no matter what. If there is any meth (or pseudo & intermediates) it will come out clean by the time you get to the third recrystallization, guaranteed. The only problem is that tweakers are not known to be patient and these things take time. It's worth it though.

Just for clarification, post reaction washing of both the hcl form and the freebase form just the way Geezmeister does it, is a very good thing.

For now.

Thank you gottagogo to have clarify this doubt in my spirit and to have taken the time known as to answer !!!
