Trimethyl citrate, C<sub>9</sub>H<sub>14</sub>O<sub>7</sub> (systematic name: trimethyl 2-hy-droxy-propane-1,2,3-tri-carboxyl-ate), <b>2</b>, was prepared by the esterification of citric acid and methanol in the presence of thionyl chloride at 273 K. The bond lengths and angles in <b>2</b> compare closely with those observed in citric acid. The C-C bonds adjacent to the terminal carboxyl groups are significantly shorter than those around the central C atom. The central carboxyl-ate group and the ...[more]
