Selective Synthesis of 1,4-Dialkylbenzenes from Terephthalic Acid
Terephthalic acid reacts with alkyl halides under Birch conditions to substituted 1,4-cyclohexadienes in high yields and good stereoselectivities. Electrophiles containing ester or nitrile groups undergo a surprising fragmentation under the reaction ...

Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Purification Of Terephthalic Acid By Supercritical Fluid Extraction
A process for the purification of terephthalic acid comprising (1) contacting an impure terephthalic acid with an amount of supercritical fluid, at a temperature and pressure, and for a period of time, sufficient to dissolve the terephthalic acid and its
core
The synthesis of terephthalic acid from biomass remains an unsolved challenge. In this study, we conducted the selective oxidation of p-cymene (synthesized from biodegradable terpenes, limonene, or eucalyptol) into terephthalic acid over a Mn–Fe mixed ...

The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

A method for producing terephthalic acid by, Comamonas testosterone DSM6577
p-Toluic acid was used as a sole source of carbon and energy to screen for a bacterium to produce terephthalic acid. Comamonas testosterone strain DSM6577 can oxidize p-toluic acid to terephthalic acid through sequential reactions catalyzed by a series ...

We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.
