Tubular Molten-Salt-Cooled Acrylic Acid Oxidation Reactor from China
This tubular reactor employs molten salt in external jackets to cool the catalyst tubes during the vapor-phase oxidation of propylene to acrylic acid, preventing hotspots. It is specifically covered by HTS 8419.89.60.00 for its cooling mechanism in acrylic acid processes involving temperature control. Ideal for high-volume production with precise thermal management.

Import Tips
• Certify molten salt compatibility with alloys to meet import material standards; provide process flow diagrams
• Avoid pitfalls by confirming 'acrylic acid' specificity in product docs
