Phosphoric Acid → HCID 178443457, compound

Participants

Reaction Steps

Xylitol decanoate was prepared. 602.5 grams of xylitol were placed in a two liter round bottom flask with a mechanical stirrer and heating mantle and temperature controller attached. 517.08 grams of decanoic acid were added to the flask. Phosphoric acid was used as the catalyst and 44.52 grams of 75% phosphoric acid was added. The reaction proceeded for 13 hours and 30 minutes. At the end of the reaction the phosphoric acid was neutralized with calcium hydroxide and the solution was filtered to remove the calcium phosphate precipitates. The free acid was measured and the value was 6.9%. The degree of reaction completion was thus 85.7%.
