Fluid phase equilibria of the reacting mixture in the dimethyl carbonate synthesis from supercritical CO2 [PDF]

, 2003
In order to investigate the dimethyl carbonate synthesis from methanol and supercritical CO2, the thermodynamic behaviour of the reacting mixture, i.e. the quaternary methanol/CO2/DMC/water mixture, has to be known.

Short-term interactions between Longmaxi shale and carbon dioxide-based fracturing fluids

Heliyon
The shale is a dense quarried rock material containing abundant shale oil/gas. Extracting shale gas usually requires fracturing the rock formation to speed up gas desorption and migration.

Methods for synthesizing diethyl carbonate from ethanol and supercritical carbon dioxide by one-pot or two-step reactions in the presence of potassium carbonate [PDF]

, 2009
Carbon dioxide sequestration was studied by synthesizing diethyl carbonate (DEC) from ethanol and CO2 under supercritical conditions in the presence of potassium carbonate as a base. The co-reagent was ethyl iodide or a concentrated strong acid.

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

Journal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.
