Procedure

The AgOH is resuspended in 400 ml of methanol. Purified tetraalkylammonium iodide (0.1 moles or 53.77 g) (Aldrich Chemical Co., Milwaukee, WI) is dissolved separately in 100 ml. of methanol and is 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 tetraheptylammonium hydroxide. A small amount of phenolphthalein 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 tetraheptylammonium acrylate. The resulting tetraheptylammonium acrylate was found to be electrically conductive.
