Participants

Reaction Steps

Sorbitol laurate was prepared in a similar manner as xylitol laurate. In this case, 600.76 grams of lauric acid and 776.01 grams of sorbitol were added to a round bottom flask. Phosphoric acid was used as the catalyst and 54.73 grams of 75% acid was added. A mechanical stirrer was used to provide the agitation and a heating mantle and temperature controller were used to control the temperature. The temperature of the reaction was set at 160° C. The reaction was stopped after 29.5 hours and the free fatty acid was high at 12.0%. The solution was neutralized with calcium hydroxide and filtered to remove the calcium phosphate precipitate. No other analysis was done on this product. The degree of reaction completion was thus 73.2%.
