3,3,5-Trimethylcyclohexanone is an excellent solvent for resins, paints, varnishes and other coatings, as well as materials such as nitrocellulose and low-molecular-weight polyvinyl chloride. Its chiral enantiomers are important intermediates in the pharmaceutical, fragrance and other industries. In industry,3, 3, 5-trimethylcyclohexanone is usually obtained through the selective hydrogenation of isophorone, with the reaction product being the racemic form. To obtain a single chiral product, further chiral separation is required.
