A (likely) unsolvable problem with ethanol extraction (keep them terps!)

@Doyathang

Can you re run it through a reflux still and achieved desired proof ?

I would usually say yes, because 95% ethanol (“azeotrope”) is the desired proof.

However, if I recall correctly, you’re asking about Isopropanol, and aiming for 99.5% which is higher than you can achieve with distillation (~91%).

Which is why you were pointed at molsieves.

@Doyathang

Can you use the carbon to higher the proof for iso 99.95 with a diluted unwanted water content

You could also google “salting out”.

why do you find Iso preferable?

Iso vs ethonal

So other then the major price difference can we talk about the pros and cons of using iso vs ethonal. For our process we work with dry sift cause the amount of trim we have comming in we can wash it. Just makes a lot more sense to freeze the material then we shake with dry ice and tumble. We legit get buckets and buckets full every run. After we do a 10:1 iso/sift. Would we get a lot more return if we washed the sift with ethonal vs iso? How does it effect the end product by using iso. Any and…
