HCID 23692638Potassium Undecylenate

Procedure

To 1/2 N-potassium hydroxide/ethanol (200 mL) is added undecylenic acid (18.8 g, 0.102 mol) slowly dropwise at 0° C. with constant stirring. The volatile matter is then distilled off to give a crude product. This crude product is washed with acetone and heated in vacuo to provide potassium undecylenate of the following formula as white solid (8.88 g, yield 88%). CH2═CH—(CH2)8—CO2−K+
