When i bought my Turbo 500 still i was given the same instructions as everyone else on how to use it based on the dvd supplied. After reading this forum it seems i have been mislead as to how i should be distilling. My question is a little lengthy but if you bare with me your feedback will be extremely helpful.
I understand alot of you will be reading this and rolling your eyes but i have read countless pages of literature on distillation and every source varies dramatically. :angry-banghead:
Therefore i am opening it up to you guys as i cannot find an explanation for my problem.
If we agree that the alcohols in the wash come off at specific temperatures.
• Acetone 56.5C (134F)
• Methanol (wood alcohol) 64C (147F)
• Ethyl acetate 77.1C (171F)
• Ethanol 78C (172F)
• 2-Propanol (rubbing alcohol) 82C (180F)
• 1-Propanol 97C (207F)
• Water 100C (212F)
• Butanol 116C (241F)
• Amyl alcohol 137.8C (280F)
• Furfural 161C (322F)
Then my understanding is that anything collected between 78-82C is Ethanol.
So when i turn on my Turbo 500, alcohol begins to drip out usually at 65-68C, by the time i collect 50ml my temperature gauge at the top of my condenser (as it is the original T500 it has 2 temperature gauges) is 78C and my water outlet temperature gauge is at 60C. I collect about 150ml total and discard this, which from the table above would be considered Aceton/Methanol/Ethyl Acetate and now my still is running at 78C, the correct temperature for me to be collecting Ethanol.
I then continue to run my still at these temperatures until the Ethanol coming out slows dramatically and switch of the still. It never goes above 80C at the top of the condenser, nor 60C at the water outlet gauge. Therefore i have not let the temperature get hot enough to collect Propanol 1 or 2 Nor anything above that.
So in theory i should have 3-4 liters of Ethanol without any heads/tails???
Why then is it necessary for me to do an initial stripping run, then re-run the same alcohol taking 200ml cuts and allow the temperature to go higher and lower than what is listed above. Dont i already have 3-4 litres of pure ethanol??
Thanks for any advise you can lend! Cheers :handgestures-thumbupleft:
