Acetic Acid → HCID 86745302, compound

Participants

Reaction Steps

6 Mol of an epoxidized oleic acid methyl ester (epoxide oxygen content: 4.61%) were stirred for 4 hours under vigorous reflux with 12 mol acetic anhydride, 10 mol % acetic acid and 1 mol % concentrated sulfuric acid. After neutralization with sodium methylate, the excess acetic anhydride was distilled off; the residue was distilled in a water jet vacuum (approx. 15 torr) up to 120° C. to remove volatile fractions of acetic anhydride. Precipitated salts were removed from the distillation residue by filtration. A brown clear liquid having the following analytical data was obtained: epoxide oxygen content 0.32%, OH value 2.6, saponification value 294.4, acid value 1.1, iodine value 14.7.
