Quantification of the Synthetic Phenolic Antioxidant Cyanox 1790 in Bottled Water with SPE-HPLC/MS/MS and Determination of the Impact of the Use of Recycled Packaging on Its Generation
(2023-02-28)
One route of exposure to SPAs is through bottled water since the polymers used to make
plastic bottles contain these SPAs, which migrate from the plastic to the water. Solid-phase extraction
(SPE), HPLC-MS, FTIR, and DSC ...
Theoretical–Experimental Study of the Action of Trace Amounts of Formaldehyde, Propionaldehyde, and Butyraldehyde as Inhibitors of the Ziegler–Natta Catalyst and the Synthesis of an Ethylene–Propylene Copolymer
(2023-02-22)
The copolymer synthesis process can be affected by failures in the production process or by contaminating compounds such as ketones, thiols, and gases, among others. These impurities act as an inhibiting agent of the ...
Cambios en el periodismo y su impacto en la autonomía profesional: evidencia del estudio The Worlds of Journalism en siete países de América LatinaA New Route of Valorization of Petrochemical Wastewater: Recovery of 1,3,5-Tris (4-tert-butyl-3-hydroxy-2,6-dimethyl benzyl)–1,3,5-triazine-2,4,6-(1H,3H,5H)-trione (Cyanox 1790) and Its Subsequent Application in a PP Matrix to Improve Its Thermal Stability
(2023-02-21)
The various chemicals in industrial wastewater can be beneficial for improving its circularity.
If extraction methods are used to capture valuable components from the wastewater and then
recirculate them throughout the ...

Applying a Green Solvent with Microwave, Ultrasound, and Soxhlet Extraction Techniques to Quantify the Slip Additive Cis-1,3-docosenamide and Nine Oxidative Degradation Byproducts in Polypropylene Samples
(2023-08-18)
Erucamide is used as an important slip agent for polymers. However, erucamide can
degrade during processing and long-term storage, forming various oxidation products. These degra dation products can affect the recovery ...
Parts per Million of Propanol and Arsine as Responsible for the Poisoning of the Propylene Polymerization Reactio
(2023-09-01)
Polypropylene synthesis is a critical process in the plastics industry, where control of
catalytic activity is essential to ensure the quality and performance of the final product. In this study,
the effect of two ...
Dimethylformamide Impurities as Propylene Polymerization Inhibito
(2023-09-18)
This research study examined how the use of dimethylformamide (DMF) as an inhibitor af fects the propylene polymerization process when using a Ziegler–Natta catalyst. Several experiments
were carried out using TiCl4/MgCl2 ...
