Caprolactam is widely used in new material fields such as textiles, electronics, automotive industry, rail transit, and aerospace. The 200,000 tons per year technology for the esterification and hydrogenation of cyclohexene to produce cyclohexanone, which was successfully developed not long ago, offers significant advantages over traditional cyclohexanone production methods, including a higher carbon yield, reduced emissions of waste gases, wastewater, and solid waste, as well as being safer, cleaner, and more efficient. Both industrial units that applied this technology achieved successful commissioning on the first attempt, producing qualified cyclohexanone while operating in a safe, stable, and optimized manner. This issue features a special report to introduce you to the newly developed, world-first technology by Sinopec for producing cyclohexanone through cyclohexene esterification and hydrogenation.
