FLEXIBLE METHOD FOR THE COMMON PRODUCTION OF FORMIC ACID, A CARBOXYLIC ACID HAVING AT LEAST TWO CARBON ATOMS, AND/OR THE DERIVATIVES OF THE SAME

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).
