Safety

Wear lab gloves and eye protection.

There is a serious fire risk - a fire extinguisher should be ready. Make sure there is nothing flammable nearby.

This experiment must be performed in a well-ventilated room or in a fume hood.

Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.

Reaction formula

((CH3)2NH2)Cl + NaOH → (CH3)2NH + NaCl + H2O

4 (CH3)2NH + 15 O2 → CO2 + 14 H2O + 2 N2

Step-by-step instruction

WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments

  1. Put some dimethylamine hydrochloride and sodium hydroxide into a test-tube.
  2. Pour some water into the-test tube. The dimethylamine gas evolves from the reaction mixture.
  3. Close the test-tube with a rubber stopper equipped with an outlet glass tube.
  4. Put a burner to the outlet tube to ignite the produced dimethylamine.

Scientific background

Dimethylamine hydrochloride and sodium hydroxide react in water forming dimethylamine gas. It is a flammable gas which reacts with oxygen forming carbon dioxide, water and nitrogen.
