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 ...
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 ...
Effects of Different Concentrations of Arsine on the Synthesis and Final Properties of Polypropylene
(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
(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 ...
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 ...
Study of the Chemical Activities of Carbon Monoxide, Carbon Dioxide, and Oxygen Traces as Critical Inhibitors of Polypropylene Synthesis
(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 ...
