功能

• As an example, put 0.2 g of MNNG (N-methyl-N '-nitro-N-nitrosoguanidine) and 0.5 mL of purified water into the reaction vessel (1), put 5 mL of ether into the recovery vessel (2), cool the lower part of the apparatus, and attach the double sphere to (4).
• Next, use a syringe to add 0.6 mL of 20% sodium hydroxide from the upper septum (3).
• Add the product carefully while observing the generation of yellow gas.
• After completion of the reaction, aeration is performed gently from step (4) to dissolve and recover in the ether of step (2).
• Diazomean is a yellow odorless toxic gas that easily explodes.
• It will decompose quickly due to light, heat, or other stimuli, so be careful when preparing it in the draft.
• Store in a cool dark place with anhydrous ether solution, but ideally prepare before use.
