Hello everyone . the thread was created due to the fact that I have a few unanswered questions.
questions :
1.should amphetamine free base (oil) be mixed with a solvent toluene / dcm etc before neutralization?
if so, in what proportions? 20-30% of the oil volume will be OK?
2. in what ratio to dilute sulfuric acid with IPA? does this affect performance?
I use a ratio of 1: 4 acid / IPA , I also used a ratio of 1:10 acid / IPA
3. What could be the cause of the drop in performance? I'm going down from the pH to 5-6. diluted acid is slowly added in portions of 50-100 ml. the agitator fired all the time. recently I added IPA to the oil (could it cause a drop in efficiency?) from a liter of oil I came out 700-800g after drying. the weight of the oil was 960g pH 12. I understand that about 960g of amphetamine sulphate should come out, right?
