De-natured alcohol vs. Acetone
This might be good information for some
of us newbs trying to think straight.
De-natured alcohol is an alcohol that is
very forgiving to rubbers,plastics,waxes
and stuff with polymers or whatever.
De-natured alcohol is used on computer printer paper rollers to clean them without eating up the rubber roller. therefore De-natured might be good for say...obtaining
RedPHOZ of of matchbooks WITHOUT carrying
too much glue off of the book with the RP.
Or soaking P/feds that are time re-lease
because it will absorb the psuedo without
breaking down the waxes in those pills
carrying wax BS over into dissolvation.
Acetone is very harsch on plastics, rubbers
waxes(some) and anything but glass metal
and some High density plastics(chlorethylene)
There fore being useful for say acetone boiling psudo mass after D-natured pulling.
Acetone can at high temperatures(hot not bioling) degrade waxes and BS from a de-natured alc. pull to be strained out and sepereated or evaporated after straining.
All in all the educated use even from a newb
can result in some of the cleanest PHoZ and
psuedo if used right....with acetone and de-natured alc.
Evaporation rates for acetone and de-natured
correspond directly to its CH and CO molecules. One is more succebtible to air than the other. VE's extraction technique
is excellent for red 60's,W/120's and up.
But 'round here I can get psuedo 60's
that have this in the ing:
Psudoephedrine HCI 60 mg
Guifanesin 200 mg
inactives: stearic acid,titanium dioxide,
and something starch. THATS IT. if someone could please tell me
what guifanesin is or what it will and will not dissolve in I can rid my Pfed mass of this bs without transferring it over to my vessel. thinking a(one) previous attemp at
reduction failed for lack of psudo that I thought was sudo....may have been 20%psudo
80% guifan. Dunno but out of 1g of { psuedo?}
all i could come up with was a .30g of the
snatch that I wanted. this is going to be unnacceptable for a larger rxn. I need to find an "easy" way to rid my psudo's of this
guifanesin from the start or from right after
d-nat pull and filter.
