Encyclopedia
Triacetone amine is the heterocycle that arises via the condensation
of acetone
and ammonia
according to the following equation:
It is used to prepare the hindered amine 2,2,6,6-tetramethylpiperidine
, CH2[CH2C(CH3)2]2NH.
Condensation
Condensation is the change of the physical state of matter from gaseous phase into liquid phase, and is the reverse of vaporization. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition....

Ammonia
Ammonia is a compound of nitrogen and hydrogen with the formula . It is a colourless gas with a characteristic pungent odour. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or...
according to the following equation:
- 3 CH3C(O)CH3 + NH3 → OC(CH2C(CH3)2)2NH + 2 H2O
It is used to prepare the hindered amine 2,2,6,6-tetramethylpiperidine
2,2,6,6-Tetramethylpiperidine
2,2,6,6-Tetramethylpiperidine or TMP or HTMP is a clear liquid with an amine odor. This amine is used in chemistry as a hindered base because it can dissolve in organic solvents unlike ordinary bases such as potassium hydroxide....
