  • Process for the production of dialkyl terephthalate
    Patent number: 11591283
    Abstract: A process for preparing dialkyl terephalate comprising the following steps:—i) providing furan-2,5-dicarboxylate; ii) esterifying the furan-2,5-dicarboxylate with alcohol to form furan-2,5-carboxylic acid dialkyl ester; iii) reacting the furan-2,5-carboxylic acid dialkyl ester with ethylene under Diels Alder conditions, elevated temperature and pressure and in the presence of a catalyst such that dialkyl terephthalate is produced; wherein the Diels-Alder reaction is free from solvent; wherein the catalyst comprises a clay comprising metal ions and having Lewis acidity.

  • Preparation of TMTHF
    Patent number: 10738021
    Abstract: A process for the preparation of 2,2,5,5-tetramethyltetrahydrofuran (TMTHF) includes contacting a TMTHF precursor with a solid catalyst, where the TMTHF precursor is 2,5-dimethylhexane-2,5-diol and/or 2,5-dimethyl-4-hexen-2-ol, and where the solid catalyst is a beta zeolite. TMTHF produced by the process may be used as a solvent.
