Production of Copolyester Monomers from Plant-Based Acrylate and Acetaldehyde

PCTA is an important copolyester that has been widely used in our daily necessities. Currently, its monomers are industrially produced from petroleum-derived xylene. To reduce the reliance on fossil energy, we herein disclose an alternative route to acces

Preparation method of terephthalic acid and diester thereof

The invention discloses a preparation method of terephthalic acid and diester thereof. Specifically, under the action of a supported metal catalyst, 2-cyclohexene-1,4-dicarboxylic acid undergoes catalytic dehydro-aromatization in a polar solvent or a nonpolar solvent so as to prepare terephthalic acid and diester. The polar solvent is water, methanol, ethanol, n-propanol, isopropanol, n-butanol, glycol dimethyl ether and diglyme. The nonpolar solvent is one or more than two components selected from a group consisting of n-hexane, n-heptane, normal octane, cyclohexane, benzene and toluene. A metal active component of the supported metal catalyst is non-noble metal and/or noble metal. A carrier for the supported metal catalyst is one or more than two components selected from a group consisting of a carbon carrier, nanoscale metal oxide, nanometer nonmetal oxide and a molecular sieve. When conversion rate of 2-cyclohexene-1,4-dicarboxylic acid is 95% and above, selectivity of terephthalic acid or diester of terephthalic acid can reach 90%.

Production of Diethyl Terephthalate from Biomass-Derived Muconic Acid

We report a cascade synthetic route to directly obtain diethyl terephthalate, a replacement for terephthalic acid, from biomass-derived muconic acid, ethanol, and ethylene. The process involves two steps: First, a substituted cyclohexene system is built through esterification and Diels-Alder reaction; then, a dehydrogenation reaction provides diethyl terephthalate. The key esterification reaction leads to improved solubility and modulates the electronic properties of muconic acid, thus promoting the Diels-Alder reaction with ethylene. With silicotungstic acid as the catalyst, nearly 100 % conversion of muconic acid was achieved, and the cycloadducts were formed with more than 99.0 % selectivity. The palladium-catalyzed dehydrogenation reaction preferentially occurs under neutral or mildly basic conditions. The total yield of diethyl terephthalate reached 80.6 % based on the amount of muconic acid used in the two-step synthetic process.
