Uses
Diazodiphenylmethane (CAS NO.883-40-9) is used for organic synthesis.
Production
Adding benzophenone hydrazone, anhydrous sodium sulfate, ethyl ether, ethanol saturated potassium hydroxide solution and yellow mercuric oxide into pressure bottle, and being shaked for 75 min, then filtered. Being decompressed to remove solvent at room temperature, and residue is dissolved in petroleum ether, filtered again. The filtrate is decompress to remove solvent, and the remaining oily matter is Diphenyldiazomethane .
Safety Profile
An unstable substance forbidden for transport. When heated to decomposition it emits toxic vapors of NOx.
