Hydrogenation of Maleic Acid to Tetrahydrofuran

At purities greater than 60%, the maleic acid begins to separate from the solution. 2.3.2 Reaction Train Maleic acid is hydrogenated to THF via a series of simultaneous reactions in a back-mix tank reactor. The reactions are a series of hydrogenations in which bonds are broken in the reacting maleic acid and chemical intermediates.

Maleic Anhydride - an overview | ScienceDirect Topics

Maleic anhydride as well as maleic and fumaric acids were first prepared in the 1830s. However, commercial manufacture did not begin until a century later. In 1933, the National Aniline and Chemical Co., Inc., used a process for producing maleic anhydride based on benzene oxidation using a vanadium oxide catalyst.
