Uses

Used in Manufacturing Industry:
PFOA is used as a key ingredient in the production of non-stick coatings for cookware, providing resistance to food sticking and making cleaning easier. Its stability and resistance to high temperatures make it an ideal component for these applications.
Used in Textile Industry:
In the textile industry, PFOA is used as a finishing agent for fabrics to confer stain resistance and repel water, grease, and oil. This enhances the durability and maintenance of clothing and other textiles.
Used in Firefighting Industry:
PFOA is also utilized in the formulation of firefighting foams, particularly for extinguishing liquid fuel fires and other types of fires that are difficult to control with water alone. Its effectiveness in these foams is attributed to its ability to suppress vapors and create a barrier between the fire and the oxygen in the air.
However, due to the environmental persistence and potential health risks associated with PFOA, there is a significant push towards finding safer alternatives and implementing stricter regulations on its use in various industries.

Synthesis and evaluation of properties of: N, N -bis(perfluorooctyl)imine acetate sodium as a gas-wetting alteration agent

The wettability of a rock's surface is a vital factor for gas flow and fracturing fluid backflow. As a result of this, novel and effective gas wetting alteration agents are required. In this work, a gas-wetting alteration agent, N,N-bis(perfluorooctyl)imine acetate sodium, was synthesized and characterized by different methods. The wettability of a rock's surface was evaluated by contact angle and imbibition measurements, the Owens two-liquid method and glass capillary tube rise testing. The results showed that after treatment with 0.5 wt% N,N-bis(perfluorooctyl)imine acetate sodium the contact angles of water and n-hexadecane on the surface of the rock increased from 36° and 0° to 140° and 119°, respectively. The surface free energy rapidly reduced from primeval 72 mN m-1 to 3.4 mN m-1 after treatment with 0.3 wt% N,N-bis(perfluorooctyl)imine acetate sodium. These values agreed with the imbibition measurements and the results of the glass capillary tube rise testing. Moreover, analysis by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) showed that the roughness of the rock surface significantly increased. The above results fully proved that the wettability of the rock surface is altered from its original water-wetting or oil-wetting to gas-wetting. Furthermore, thermal analysis demonstrated that the gas-wetting alteration agent has good thermal stability, which indicates its great potential to be used as a gas-wetting alteration agent for unconventional gas reservoirs under high temperature conditions.

Micelle Formation in Liquid Ammonia

Perfluorinated long chain alkyl amides aggregate in liquid ammonia with increasing concentration which reflects micelle-type formation based on changes in 19F NMR chemical shifts. The critical micelle concentrations (cmc) decrease with increasing chain length and give Kleven parameters A = 0.18 and B = 0.19. The micelles catalyze the ammonolysis of esters in liquid ammonia. The corresponding perfluorinated long chain alkyl carboxylates form ion pairs in liquid ammonia, but the equilibrium dissociation constants indicate favorable interactions between the chains in addition to the electrostatic forces. These perfluorinated carboxylates form micelles in aqueous solution, and their cmc's generate a Kleven B-value = 0.52 compared with 0.30 for the analogous alkyl carboxylates. The differences in hydrophobicity of CH2 and CF2 units in water and liquid ammonia are discussed, as is the possible relevance to life forms in liquid ammonia.
