Trimethylhexamethylenediamine is the name used to refer to a mixture of two isomers of trimethyl-1,6-hexanediamine.The mixture is used as a monomer in nylon TMDT. It is available commercially under the trade name Vestamin TMD from the company Evonik Industries.
Trimethylhexamethylenediamine is synthesized from isophorone.[1] Isophorone is reduced by hydrogenation to the trimethylcyclohexanol, which is then oxidized with nitric acid (in the same fashion as adipic acid is synthesized from cyclohexane). The diacid, again a mixture of two "trimethyladipic acids", is converted to the diamine via the dinitrile.[2]
TMD is used as a component in certain curing agents for epoxy resins.[3]
