Jake – you should be able to distill and reuse the hexane and ethyl acetate. The boiling points are significantly different (68C and 77C) so they’ll come off separately. This is NOT illegal treatment, but the waste must be managed as hazardous UNTIL it has been reclaimed. As a large generator, you will need to run a batch at least once every 90 days. Anything that isn’t reclaimed will still be regulated as hazardous waste, including your still bottoms.

Subject: [DCHAS-L] Quick question for the group



Our university just recently became a large quantity waste generator. We have been trying to find ways to reduce/reuse/recycle. One of our largest wastes is from the organic chemists. The waste in question is hexane/ethyl acetate. Has anyone heard of a way to separate these two and reuse them?


Thank you,
