Compound 10a is an ester with a molecular formula of CsH₂O). When 10a is allowed to react with glycerin in the presence of an acid catalyst a triester (10b) is generated. This triester reacts remarkably fast when treated with sodium ethoxide in ethyl acetate as the solvent giving two products: 10c (an ester) and 10d (a triester).
