Hi,

Does anyone know if Methylene Chloride and Copper react?

I am investigating a cooling system using Methylene Chloride and plan on using Copper, but am not sure if it reacts.

If it does, can you explain.

Thanks

Dont think so, but just to be sure get a small piece of copper and submerge it in some DCM for a prologned period, copper isnt particularly active in reactivity (under normal conditions) so if there is a reaction it would be over a period of time.

This is from the MSDS for copper metal -->
Copper is incompatible with oxidizers, alkalis, acetylene, chlorine plus oxygen difluoride, phosphorus, nitric acid, potassium peroxide, 1-bromo-2-propyne, sulfur plus chlorates. Reacts violently with ammonium nitrate, bromates, iodates, chlorates, ethylene oxide, hydrozoic acid, potassium oxide, dimethyl sulfoxide plus trichloroacetic acid, hydrogen peroxide, sodium peroxide, sodium azide, sulfuric acid, hydrogen sulfide plus air, and lead azide. A potentially explosive reaction occurs with actylenic compounds. Copper ignites on contact with chlorine, fluorine (above 121C), chlorine trifluoride, and hydrazinum nitrate (above 70C). An incandescent reaction occurs with potassium dioxide.

Doesnt sound like DCM flowing through copper pipes (i assume this is what you meant?) would be a problem but just do the check like a outlined above to be sure.
