Stearic Acid → Cyclododeca-1,3,5-triene

Participants

Reaction Steps

A 600 mL beaker was charged with 150 g deionized water, 100 g of 91% pure 1,5,9-cyclododecatriene and 5.0 g of stearic acid. The resulting mixture was heated to 75°-80° C. to melt stearic acid and was intensively mixed at this temperature using a high shear Tekmar agitator while adding sufficient 50% aq. KOH to raise the pH to 10.5-11.0. The emulsion was cooled to room temperature and allowed to stand overnight. (Note: density differences between bulk water and emulsified particles caused some separation overnight, but gentle mixing again gave a uniform emulsion). The final emulsion contained 39.2 percent 1,5,9-cyclododecatriene (I) by weight.
