A recently granted patent (Publication Number: US11884622B2) discloses a tricyclodecane dimethanol composition that includes tricyclodecane dimethanol and an ether compound represented by a specific formula in a minimal amount. The composition may also contain a C11-12 diol compound in a limited quantity. The patent further details a method for preparing this composition, involving various steps such as purifying dicyclopentadiene, performing hydroformylation and hydrogenation reactions, as well as thin film evaporation and vacuum fractional distillation processes. The method aims to produce a high-quality tricyclodecane dimethanol composition with specific characteristics.
Moreover, the patent outlines specific conditions for each step of the preparation method, including temperature ranges, reaction pressures, catalyst compositions, and addition rates of dicyclopentadiene. For instance, the retro Diels-Alder reaction of dicyclopentadiene is conducted at 150°C to 250°C, while the hydrogenation reaction is carried out at 80°C to 250°C under a pressure of 20 bar to 200 bar. Additionally, the inclusion of an organophosphorus compound in a defined ratio per mole of rhodium in the catalyst composition is highlighted. These detailed instructions aim to ensure the efficient and controlled production of the tricyclodecane dimethanol composition with minimal impurities and optimal chemical properties.
