Description
General description
For technical and safety information about Diazald and Aldrich diazomethane generators see Technical Information Bulletin AL-180.
For the large-scale (200 to 300 mmol) generation of diazomethane. The dry ice condenser quantitatively condenses all the diazomethane/ether vapor during diazomethane generation from Diazald. Designed by M. Hudlicky [J. Org. Chem., 1980, 45, 5377]. The stopcock is closed at the start of distillation. As the distillate drips off the condenser, the stopcock is opened and the first portions fill the trap, allowing diazomethane/ether condensate to collect in the 500 mL Erlenmeyer flask, but prevents the escape of uncondensed vapors into the receiver. Glassware has Clear-Seal® joints, which do not require grease and are safer because of their smooth surfaces (sharp edges and ground glass must be avoided in diazomethane generation). Thermometer not included.

NOTE: Sigma-Aldrich is unable to supply certain Diazomethane precursors in some countries. Check availability of starting materials prior to glassware purchase.
