2,6-DIMETHYL-2,4,6-OCTATRIENE Usage And Synthesis

Definition

ChEBI: (4E,6E)-2,6-dimethylocta-2,4,6-triene is an ocimene that consists of octa-2,4,6-triene bearing methyl substituents at positions 2 and 6 (the 4E,6E-isomer). It has a role as a semiochemical.

Purification Methods

Fractionally distil allocimene through an efficient column and repeatedly distil it at 15mm through a long column of glass helices, with a final distillation from sodium under nitrogen. It should be stabilised with ca 0.1% of hydroquinone. UV: max nm( 1cm-1) 290 (32 500), 279 (41 900) and 278 (42,870). [Alder et al.
