Raws li xyoo 2025, lub ntiaj teb cyclohexanone noj ntau tshaj 3.7 lab metric tons, nrog kwv yees li 70% coj mus rau Nylon 6 thiab Nylon 66 tus nqi chains. Caprolactam- ua los ntawm cyclohexanone oxime tsim ua raws li Beckmann rearrangement- yog monomer rau Nylon 6. Adipic acid, tau los ntawm nitric acid oxidation ntawm KA roj, yog lub monomer rau Nylon 66. Caprolactam daim ntawv thov nyiaj rau kwv yees li 59.1% ntawm cyclohexanone kev lag luam 22.0%
Paints thiab Coatings
Nrog rau tus nqi KB ntawm 95-98, cyclohexanone ua tiav kev ua tiav ntawm nitrocellulose, alkyd, epoxy, vinyl, thiab acrylic resin systems. Nws qhov nruab nrab evaporation tus nqi tswj cov yeeb yaj kiab tsim thiab txo qhov tsis xws luag xws li blushing thiab cratering. Siv rau hauv kev lag luam tu coatings, marine topcoats, automotive OEM thiab refinish systems, thiab ntoo tiav. Kev thov hauv cov ntawv thov hnyav rau cov xim, cov ntawv pleev xim, thiab cov coatings tau nce li ntawm 5% txhua xyoo ntawm 2022 thiab 2025.
