Abstract
1506469 Potassium disorbate HOECHST AG 10 June 1975 [12 June 1974] 24846/75 Heading C2C A sorbic acid-potassium sorbate addition compound, C 6 H 8 O 2 .C 6 H 7 O 2 K, is prepared by mixing 12-40 parts by weight sorbic acid and 40-58 parts by weight potassium sorbate in an aqueous solution, with the weight of potassium sorbate with respect to the sum of the weights of potassium sorbate and water being 40-58%, and crystallizing the addition compound. A temperature of 45 to 95C. is used and the solution may be purified by an adsorbent such as active coal, boneblack, kieselguhr, bauxite, bentonite or an adsorption resin.
