A mixture of 5.0 g (0.0156 mole) of (E)-3-[5-(1-oxododecyl)-2-furanyl]-2-propenoic acid, 1.0 g of potassium hydroxide and 100 ml of methanol is heated with stirring on a steam bath for 1 hour. The methanol is distilled off to 50 ml and the mixture cooled. The solid is separated by filtration to give potassium (E)-3-[5-(1-oxododecyl)-2-furanyl]-2-propenoate, m.p. 220°-230° C. (decomposition).
