Publication number: 20180022676Abstract: Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.Type: ApplicationFiled: September 29, 2017Publication date: January 25, 2018Applicant: Eastman Chemical CompanyInventors: Venkata Bharat Boppana, Kenneth Wayne Hampton, JR., Zhufang Liu, Charles Edwan Sumner, JR., Gerald Charles Tustin, Guy Ralph Steinmetz, Melissa Page Steffey

Publication number: 20160068655Abstract: The invention relates to a process that integrates the oxidation of toluene to benzoic acid with the production of benzoate plasticizers. Toluene is fed to an oxidation vessel in the presence of oxygen and an oxidation catalyst wherein benzoic acid serves as the solvent for the oxidation. The crude benzoic acid produced is not purified and is then reacted with an alcohol in the presence of an esterification catalyst to produce the crude benzoate ester. The oxidation catalyst, esterification catalyst, and other impurities can be mostly removed from the crude benzoate ester in subsequent washing and filtering steps. The benzoate esters produced through this method can be made in fewer steps with both yields and purities above 80%.Type: ApplicationFiled: November 13, 2015Publication date: March 10, 2016Applicant: EASTMAN CHEMICAL COMPANYInventors: Pinguan Zheng, Jonathan J.
