Patent number: 10233410Abstract: A novel minimum boiling binary azeotrope of n-undecane and n-butyl-3-hydroxybutyrate is shown to have utility as a solvent for degreasing of both nonpolar and polar contaminants. The components of the azeotrope are stable against degradation and the composition is largely invariant with pressure, yielding a unique solvent that can be used in cold cleaning and in vapor degreasing at elevated temperatures and over a wide range of pressures.Type: GrantFiled: June 15, 2017Date of Patent: March 19, 2019Assignee: Eastman Chemical CompanyInventors: Travis Matthew Gott, Venkata Bharat Ram Boppana

Patent number: 9493390Abstract: 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: February 19, 2015Date of Patent: November 15, 2016Assignee: EASTMAN CHEMICAL COMPANYInventors: Venkata Bharat Ram Boppana, David William Norman, Melissa Page Steffey
