摘要:
Joint production of formic acid with a \- 2C carboxylic acid (or derivative) involves transesterifying a formic ester (I) with a \- 2C carboxylic acid (II) to give formic acid (III) and the corresponding carboxylic acid ester (IV), and carbonylating part of (IV) to the corresponding carboxylic acid anhydride (V).
