Patent number: 7563926Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.Type: GrantFiled: June 16, 2005Date of Patent: July 21, 2009Assignee: Eastman Chemical CompanyInventors: Marcel de Vreede, Lee Reynolds Partin, Wayne Scott Strasser

Patent number: 6036885Abstract: A cellulosic ester has associated with the ester at least one near infrared fluorophore. A method for incorporating the near infred fluorophore into the cellulosic ester is also provided. In the method, the near infrared fluorophore is dissolved in a strong acid and precipitated to form an acid paste. The paste is then added to an activated cellulose, such as a hydrolyzed cellulose acetate, in the presence of at least one acid and acid anhydride. Advantageously, such marked cellulosic materials can be solvent spun into staple fibers which may be further utilized in known materials, webs and articles.Type: GrantFiled: September 15, 1998Date of Patent: March 14, 2000Assignee: Eastman Chemical CompanyInventors: James John Krutak, Sr., Thomas Vernon McCray, Edwin Taylor Boyd, Fred Dewey Barlow, Jr., Melvin Glenn Mitchell, Lee Reynolds Partin
