Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). |
As implied by its name, it is a trimeric species formed from the reaction of acetaldehyde and ammonia:
- 3 CH3CHO + 3 NH3 → (CH3CHNH)3 + 3 H2O
Studies using NMR spectroscopy indicate that the three methyl groups are equatorial, thus the molecule has C3v point group symmetry.[2]
The compound is related to hexamethylenetetramine, which is the condensation product of ammonia and formaldehyde.
