Did this researcher even READ the SDS's?  Here's an excerpt from the Fisher SDS for dichloromethane: https://www.fishersci.com/msdsproxy%3FproductName%3DD3720%26productDescr

Forms a detonable mixture with nitric acid.

THIS IS NOT WORTH THE RISK.  SUBSTITUTE, SUBSTITUTE, SUBSTITUTE.  https://www.cdc.gov/niosh/topics/hierarchy/default.html  

Let me refer you here:  http://www.ilpi.com/safety/explosion.html  All because of one momentary lapse, a student almost lost an eye, and I came within seconds of having to pull two burning or unconscious faculty peers out of a situation they should not have tried to fight on their own. It's unbelievable there were no injuries.

Hello,
I had a question from one of the organic chemists here about how to store the waste from a nitration using nitric acid in a dichloromentane/acetic acid solvent. He says there are several examples of this nitration in the literature, but I am still wary. While the reaction is open to the atmosphere, I am worried about storing it until it can be disposed of. Any advice would be greatly appreciated.
