The closest thing I can think of off-hand is dimethylformamide and carbon
tetrachloride.  The MSDS(Aldrich?)of either probably has an incompatibility
Other than that, the only danger (that I can think of) is the more flammable
non-halogenated substance heating the halogenated solvents to decompose
during a fire, but then the fire is probably a greater concern and
separation might not help that much.

Subject: [DCHAS-L] Storage of Chlorinated Solvents and Flammables


I have asked our staff to store chlorinated solvents separately from
flammable substances.  I know that this is generally good practice, but I
also read that some chlorinated solvents can react with some flammables to
produce phosgene, and perhaps other toxic gases as well.  This made some
sense to me since I know chlorinated solvents can produce these gases when
exposed to heat or UV.

I am being challenged on this and asked to produce the names of flammables
that will react with chlorinated solvents upon contact to produce dangerous
gases.  Does anyone have information on this?   Are there other compelling
reasons not to store chlorinated solvents with flammables?
