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.
Acetaldehyde is an important precursor to pyridine derivatives, pentaerythritol, and crotonaldehyde. Urea and acetaldehyde combine to give a useful resin. Acetic anhydride reacts with acetaldehyde to give ethylidene diacetate, a precursor to vinyl acetate, which is used to produce polyvinyl acetate. [24] The global market for acetaldehyde is ...
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.
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 ...
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.
