In this communication, we describe p-xylene oxidation with molecular oxygen at 373 K and atmospheric pressure using N-hydroximide catalysts. p-Xylene conversion was rather high over the first 2 h of reaction and complete by the end of the experiment. The product distribution curves versus reaction time are typical of consecutive reactions. The main intermediate product is p-toluic acid. Peak co...

A pad-plate method of assaying residual amounts of chlortetracycline (CTC) and oxytetracycline (OTC) using Bacillus cereus 213 was used to determine amounts of antibiotic left in tissues and eggs of poultry fed 1,000 and 200 ppm of CTC and OTC in basal feed mixtures. The effects of various methods of cooking the tissues and eggs and the potentiating effect of terephthalic acid (TPA) were studie...

Exploiting biomass as an alternative to petrochemicals for the production of commodity plastics is vitally important if we are to become a more sustainable society. Here, we report a synthetic route for the production of terephthalic acid (TPA), the monomer of the widely used thermoplastic polymer poly(ethylene terephthalate) (PET), from the biomass-derived starting material furfural. Biobased ...

In the title compound, C(12)H(10)N(4)·C(8)H(6)O(4), 1,4-bis-(imidazol-1-yl)benzene and terephthalic acid mol-ecules are joined via strong O-H⋯N hydrogen bonds to form infinite zigzag chains. Both mol-ecules are located on crystallographic inversion centers. The O-H⋯N hydrogen-bonded chains are assembled into two-dimensional layers through weak C-H⋯O and strong π-π stacking inter-actions [centro...

In this study, a Cu–Ce@Az ozone catalyst with multiple active components was prepared through the impregnation method to treat purified terephthalic acid (PTA) wastewater, and characterized by X-ray diffraction, fluorescence spectroscopy, scanning electron microscopy, specific surface area analysis, energy photoelectron other methods. The had developed pore structure large crystal structure. Af...

The adsorption of terephthalic acid molecules [C(6)H(4)(COOH)(2)), TPA] on a single layer of graphene grown epitaxially on Ni(111) has been investigated by means of near-edge X-ray absorption fine structure (NEXAFS) spectroscopy and X-ray photoelectron spectroscopy (XPS) at room temperature. The assignment of the NEXAFS resonances was aided by ab initio calculations for the free TPA molecule. F...

The alkaline depolymerization reaction of poly(ethylene terephthalate) (PET) under quasi-solvent-free conditions was investigated. This is a new approach for recycling PET waste to its monomer building blocks: terephthalic acid and ethylene glycol. influence base particle size, temperature, rotational speed the employed laboratory kneader on yield in quasi-solid-solid depolymerized almost quant...

Due to the presence of dyes and additives, textile recycling is challenging, therefore majority waste downcycled low-value products, incinerated or landfilled. In this study, a continuous depolymerization post-consumer polyester textiles was conducted by alkaline hydrolysis. The degree assessed found be 94 %. After recovering analyzing terephthalic acid ethylene glycol monomers were successfull...
