Cooking wine is actually kind of "dirty". It's full of congeners, some of which also form azeotropes. I strongly recommend using a double Vigreaux column to make temperature fractions as sharp as possible. The heads will contain crap like methanol and ethanal. The tails will contain higher alcohols and their azeotropes. If purity is a serious concern, I would carefully redistill the hearts before further processing. Great video! 💯
Thanks for the input, congeners are definitely something I should take into account but unfortunately MSDS are not available for cooking wine. For getting higher purity ethanol, I also would recommend doubling the length for the fractionating column to allow precise control, although you might not want to do it inside a fumehood (It shouldn't fit).
Your editing is phenomenal, and your setup is spotless unlike mine 😅, liked and subscribed. Btw I’m doing this rn, however mine contains 95% ethanol, and a few point percent of denatonium benzoate and methyl isobutyl ketone. Great video !
Thanks for your compliment, I did cleaning between shots as I have OCD, my usual setup for testing wasn't as clean though. I make ethanol from cooking wine specifically because I found my denatured ethanol has too much unwanted impurities in it that could affect my reaction.
@@DangerousLab Kinda wish i had OCD now so my lab would be clean , Using cooking wine is smart, just stopped the distillation due to the small amount of ketone probably coming over, in total around 3ml in 900ml of liquid so hard to keep them separated during distillation, should've realised earlier. Have to figure out other routes now... Reason I want to try this is that denatured ethanol is so cheap in abundance, I can get litres for a mere 10 dollars.
The cost calculation needs your working time as well, considering that the procedure takes several hours to a full day at least, so that's the biggest factor
That's total true. Indeed, the biggest limiting factor for me is the time and lab space it occupied, I can only run a single distillation at a time, I will also account for this in any future videos regarding cost calculation.
Oh ya sorry, I forgot to include that book, I should have included it too in the reference. I will update it after I get back to my lab, but that book is pretty old though, I will probably include a few more recommendations as well for your info.
I have added 2 books to the reference section, the one shown in the video is "Practical Skills in Chemistry". My production cycle is a bit long, so next video probably take 2 months, hope to see you there!
I’ve noticed a drying powder added to the ‘cotton’ that comes inside your aspirin bottle, and I would like to know what it is. Maybe it says on the label?
I am not aware that there is drying powder being added to the cotton in aspirin bottle, the cotton is usually there to prevent pills being shaken excessively during transport, I suspect the powder you saw might be some binder of the pills stuck onto it.
