Molten-Salt-Cooled Acrylic Acid Fixed-Bed Reactor from Japan
This industrial reactor facilitates the catalytic oxidation of propylene to acrylic acid using a molten salt cooling system to manage the highly exothermic reaction and maintain optimal temperatures. It falls under HTS 8419.89.60.00 as specialized machinery for chemical processing involving temperature change via cooling in acrylic acid production. The design ensures efficient heat transfer for high-purity output.
