432.44 grams of octanoic acid was put into a 2-liter round bottom, three-neck flask with a short distillation head. A mechanical stirrer was connected and 598.51 grams of sorbitol was slowly added. The catalyst in the reaction was phosphoric acid and 30.93 grams were added. A temperature controller and heating mantle were attached and the temperature of the reaction was set at 150° C. The reaction was stopped after 21 hours. The phosphoric was neutralized with 26.02 grams of calcium hydroxide. The solution was filtered to remove the calcium phosphate precipitate. The density of the product was 1.4 g/cc and the free acid was 6.40%. The degree of reaction completion was thus about 85.5%
