Hi Margaret:

What is the objective of distilling acids, and what are those acids. Make sure that proper hazard assessment is done. Sulfuric acid and nitric acids can pose significant hazard at elevated temperature. Good luck.

We are in the early stages of preparing for a new researcher who plans to distill various mineral acids using a commercially available acid still. This is totally new ground for me/the college--and I am looking for guidance, SOPs, 'What I wish we knew then' stories.

Also we are constructing a soft-sided clean room for said researcher, who will add two positively pressured laminar flow hoods and 1-2 "zero pressure" enclosures. My understanding currently is that the acid still will go in one of the zero-pressure enclosures (which is a higher level of 'clean' than the outer 'clean' room). The soft-sided clean room will be contained within a larger, negatively pressured lab.

If you have any experience with a setup like this, I would love to hear about it whether that's an email to the listserv, or we arrange a phone call or whatever.

Many thanks!
Margaret
