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

Patent number: 9573119Abstract: The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed. Additionally, the catalyst composition is catalytically active towards the formation of acrylic acid from methylene diacetate and methacrylic acid from methylene dipropionate; both reactions are carried out with high space time yields.Type: GrantFiled: September 21, 2015Date of Patent: February 21, 2017Assignee: EASTMAN CHEMICAL COMPANYInventors: Liu Deng, David William Norman, Gerald Charles Tustin, Bharat Venkata Boppana, Melissa Page Steffey
