  • Publication number: 20230030777
    Abstract: Provided is a process for depolymerization of a poly(C2-C4 alkylene terephthalate), which comprises contacting a poly(C2-C4 alkylene terephthalate) with methanol and a catalyst chosen from potassium carbonate, sodium carbonate, magnesium methoxide, 1,8-diazabicyclo[5.4.0]undec-7-ene, and triazabicyclodecene, at a temperature sufficient to effect said depolymerization. The process of the invention can be carried out a substantially lower temperature and requires less methanol than necessary for zinc acetate-catalyzed reactions, and is sufficiently robust to tolerate lower-quality poly(C2-C4 alkylene terephthalate) scrap feeds.

  • Publication number: 20230024745
    Abstract: 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.
