10,12-Pentacosadiynoic acid → Methyl 10,12-tricosadiynoate

Participants

Reaction Steps

Alcoholic Monomer Solution of TDA/PDA: 10,12-Tricosadiynoic acid (TDA, 6 gm GFS Chemicals) and 10,12-pentacosadiynoic acid (PDA, 0.9 gm GFS Chemicals) were dissolved in 60 ml ethanol (Fisher). The solution was slightly warmed and stirred. The solution (TDA/PDA) was filtered (Whatman No. 1) to remove residual polymer. Dye colorant could be added to the alcoholic monomer solution as an indicator. Standard organic solvent based dyes were added at 2 drops per ml.
