You’re likely to have a decarbed product going 70°c all the way thru. That’s not why I posted the boiling point picture though, I posted the boiling point picture to show you the temperature at which ethanol boils under a vacuum so that you know what temperature to evaporate just the ethanol off. My solid advice is to get a better pump and keep up with the cooling along the way.
I’ve put in golden winterized mixtures and gotten dark orange shit that would be better for eating cause I used to take my RotoVap to 70°c. I learned that lesson last year.
