WebJan 25, 2024 · Fine Chemical Synthesis Hydrogenation reactions. Hydrogenation reaction has been widely considered as one of the most critical reactions in industry. It is extensively employed in various industrial processes to synthesize a wide variety of products, including fine chemicals. In terms of molecular structure, one distinguishes first between low-molecular-weight (LMW) and high-molecular-weight (HMW) products. The generally accepted threshold between LMW and HMW is a molecular weight of about 700. LMW fine chemicals, also designated as small molecules, are produced by traditional chemical synthesis, by microorganisms (fermentation or biotransfor…
