Publication number: 20230024745Abstract: An esterification process that uses an acetic acid composition from a wood acetylation process as a reactant. Even though the acetic acid composition contains impurities, such as ethyl acetate, methyl acetate, acetaldehyde, acetone, terpenes and/or terpenes derivatives, the impurities do not adversely affect the quality of the ether-ester products. This process can be economically advantageous by using cheaper acetic acid—one sourced directly from a wood acetylation process.Type: ApplicationFiled: December 16, 2019Publication date: January 26, 2023Applicant: EASTMAN CHEMICAL COMPANYInventors: MESFIN EJERSSA JANKA, KEVIN JOHN FONTENOT

Patent number: 9388111Abstract: Disclosed is a method for purifying aromatic dicarboxylic acid such as isophthalic acid or terephthalic acid. The process treats a crude carboxylic acid (CCA) composition by feeding a CCA composition comprising a liquid and a solid to a filter cake formation zone to form a CCA wet cake composition and a first mother liquor stream; dewatering said CCA wet cake composition to form a dewatered CCA wet cake composition having a second liquid level that is lower than the first liquid level or having no liquid level and a second mother liquor stream; and washing the dewatered CCA wet cake composition with a wash stream in a wash zone to forma washed CCA wet cake composition and a wash liquor stream.Type: GrantFiled: December 27, 2013Date of Patent: July 12, 2016Assignee: Eastman Chemical CompanyInventors: Kenny Randolph Parker, Jennifer Caroline Moffitt, Kevin John Fontenot
