Reaction Steps

The AgOH is resuspended in 400 ml of methanol. The purified tetraalkylammonium iodide (0.1 moles or 48.2 g) (Aldrich Chemical Co., Milwaukee, Wis.) is dissolved separately in 100 ml. of methanol and added to the AgOH suspension. Almost immediately, the AgOh develops a greenish cast. The mixture is stirred for an hour and then filtered through a sintered-glass funnel. The filtrate now contains 0.1 moles of tetrahexylammonium hydroxide. A small amount of phenophthalein is added, turning the solution red indicating that the solution is basic. Acrylic acid is added until the red color disappears. The methanol is removed by evaporation in a rotary flash evaporator leaving tetrahexylammonium acrylate. The resulting tetrahexylammonium acrylate was found to be electrically conductive.
