Acetaldehyde ammonia trimer is a chemical compound described by the formula (CH 3 CHNH) 3. The pure material is colourless but samples often appear light yellow or slightly beige due to the degradation by oxidation. It is hygroscopic, and can be found in a trihydrate form.
Paraldehyde is the cyclic trimer of acetaldehyde molecules. [2] Formally, it is a derivative of 1,3,5-trioxane, with a methyl group substituted for a hydrogen atom at each carbon. The corresponding tetramer is metaldehyde. A colourless liquid, it is sparingly soluble in water and highly soluble in ethanol.
Three molecules of acetaldehyde condense to form "paraldehyde", a cyclic trimer containing C-O single bonds. Similarly condensation of four molecules of acetaldehyde give the cyclic molecule metaldehyde. Paraldehyde can be produced in good yields, using a sulfuric acid catalyst.
In chemistry, a trimer (/ ˈ t r aɪ m ər /; from Ancient Greek tri- 'three' and -mer 'parts') is a molecule or polyatomic anion formed by combination or association of three molecules or ions of the same substance. In technical jargon, a trimer is a kind of oligomer derived from three identical precursors often in competition with polymerization.
Acetaldehyde ammonia trimer is the cyclic trimer formed in the condensation reaction of acetaldehyde with ammonia: 3 CH 3 CHO + 3 NH 3 → (CH 3 CHNH) 3 + 3 H 2 O. The aldehyde ammonia does not need to be isolated as an intermediate. The configuration of the three methyl groups in thialdine can differ, so that multiple cis-trans isomers are ...
Ethanimine is an organonitrogen compound classified as an imine.It is formed by reacting acetaldehyde and ammonia, but rapidly polymerizes to acetaldehyde ammonia trimer.. It has two tautomers: ethanimine, an imine, and ethenamine or aminoethylene, an amine.

Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
