The Beckmann rearrangement into e-caprolactam is one of the most industrially
important acid-catalyzed reactions, which is the starting monomer
for the production of nylon 6. However, its practical production has
suffered from serious disadvantages of using environmentally damaging
catalysts such as highly concentrated sulfuric acid and of forming
large quantities of valueless by-products such as ammonium sulfate.
We demonstrate that our supercritical water microreaction system can
achieve a high selectivity in a satisfactory yield for the e-caprolactam
production even in the absence of any acids.
