Swig n Co have been playing with the STE of late.
Since Blue Sulfates are swigs game, the STE forms the first part of the extraction method. Also in this part of the world VM&P naptha is non-existent. Experimentors substituted White Spirits (WS) for VM&P, as after extensive searching found similar properties with boiling point, fuel fraction etc.
So its off to work we go.
The iso - WS hot extraction of the pills works fantastic! This will certainly become a standard start to the clean, as the G man hates crushing.
The problems began when evapping off the iso. Blue dye/wax comes out of the hot solution as the iso boils, leaving a heavy sticky residue. Hot MEK does clean this up, although
after several boils the pm retains a blue colour.
being an impatient lad, swig probably over-basified his A/B
(standard water A/B this time!!)
destroying his yield ( < 50% on 12 packs )
However, obtained pfed HCl was of a much higher quality then has been seen on the last few outings, with a high smokeability rating ( as a test ).
Since toluene is used as the np in the A/B, some pre A/B - post STE boils in the stuff are going to be attempted, as are further MEK and or tone washes.
Following that, swig wants to try a WAB into tone, cos titrations fuck him off.
Cheers and goodnite
