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.^[2] 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.^[3]

Uses

TMD is used as a component in certain curing agents for epoxy resins.^[4]
