Methyl ester column

A solution of 88 g. (l mole) of freshly distilled pyruvic acid, 1 128 g. (4 moles) of absolute methanol, 350 ml. of benzene, and 0.2 g. of -toluenesulfonic acid is placed in a 1-1. round-bottomed flask connected through a ground-glass joint (Note 1) to a methyl ester column shown in Fig. 1 2 (Note 2). The column is fitted at...
