Publication number: 20120302772Abstract: Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.Type: ApplicationFiled: September 9, 2011Publication date: November 29, 2012Applicant: EASTMAN CHEMICAL COMPANYInventors: Ashfaq Shaikh, Mesfin Ejerssa Janka, David Milton Lange, Michael C. Morrow, Bradford Russell Bowers, Kenny Randolph Parker, Lee Reynolds Partin, Jason Christopher Jenkins, Paula Moody, Thomas Elbert Shanks, Charles Edwan Sumner, JR.

Patent number: 8178054Abstract: 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: February 9, 2010Date of Patent: May 15, 2012Assignee: Grupo Petrotemex, S. A. DE C. V.Inventors: Alan George Wonders, Lee Reynolds Partin, Wayne Scott Strasser, Marcel de Vreede
