Undecylenic acid (18.8 g, 0.102 mol) was added dropwise gradually to ½ N ethanolic solution of potassium hydroxide (200 mL) with stirring at 0° C. The volatile matter was distilled off under reduced pressure to give a crude product. The crude product was washed with acetone and heated under reduced pressure to give potassium undecylenate represented by the formula given below as a white solid (8.88 g, yield 88%). CH2═CH—(CH2)8—CO2−K+
