Dimethylformamide Impurities as Propylene Polymerization Inhibito
(Cartagena de IndiasCampus Tecnológico, 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 ... -
Effects of Different Concentrations of Arsine on the Synthesis and Final Properties of Polypropylene
(Cartagena de Indias, 2022-07-31)This article studies the effects of arsine on the synthesis and thermal degradation of 4 sam ples of virgin polypropylene (PP-virgin) and proposes reaction mechanisms that allow understanding of its behaviour. Different ... -
Impact of Traces of Hydrogen Sulfide on the Efficiency of Ziegler–Natta Catalyst on the Final Properties of Polypropylene
(Cartagena de Indias, 2022-09-19)Sulfur compounds are removed from propylene through purification processes. However, these processes are not 100% effective, so low concentrations of compounds such as H2S may be present in polymer-grade propylene. This ... -
Linear model to estimate the degradation index on the processing of recycled polypropylene due to the addition of stabilizer
(Universidad de Tarapaca, 2016)In the present research work, a lineal model to estimate the Processing Degradation Index (PDI) of polypropylene from recycled industrial waste and municipal solid waste is presented. According to the previous thing an ... -
Parts per Million of Propanol and Arsine as Responsible for the Poisoning of the Propylene Polymerization Reactio
(Cartagena de Indias, 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 ... -
Recovery of (Z)-13-Docosenamide from Industrial Wastewater and Its Application in the Production of Virgin Polypropylene to Improve the Coefficient of Friction in Film Type Applications
(Cartagena de Indias, 2023-01-09)Additives play an important role in the production of plastic materials through their application, in which the mechanical, thermal, and physical properties of polymers are improved, making them last longer and be more ... -
Study of the Chemical Activities of Carbon Monoxide, Carbon Dioxide, and Oxygen Traces as Critical Inhibitors of Polypropylene Synthesis
(Cartagena de IndiasCampus Tecnológico, 2024-02-23)This study outlines the investigation into how the compounds CO2 , CO, and O2 interact with the active center of titanium (Ti) on the surface of MgCl2 and how these interactions impact the productivity of the Ziegler–Natta ... -
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
(Cartagena de IndiasCampus Tecnológico, 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 ... -
Valoration of the Synthetic Antioxidant Tris-(Diterbutyl-Phenol)-Phosphite (Irgafos P-168) from Industrial Wastewater and Application in Polypropylene Matrices to Minimize Its Thermal Degradation
(Cartagena de IndiasCampus Tecnológico, 2023-04-02)Industrial wastewater from petrochemical processes is an essential source of the synthetic phenolic phosphite antioxidant (Irgafos P-168), which negatively affects the environment. For the determination and analysis of ...
