Fluorocarbon surfactants were the main components of aqueous film-forming foam extinguishing agents (AFFF). Unfortunately, the widely used fluorocarbon surfactant perfluorooctane sulfonate (PFOS) was limited due to its toxicity, bioaccumulation and biodegradability. In this paper, an environmentally friendly quaternary ammonium cationic fluorocarbon surfactant with high surface activity and simple synthesis route was reported. The surface performance and aggregation behavior of the mixed solution of this fluorocarbon surfactant and sodium n-octyl sulfate were studied by means of surface tension meter and transmission electron microscope (TEM). The results showed that the synergistic effect of sodium n-octyl sulfate and this fluorocarbon surfactant was significant, and many vesicles could be observed in the mixed solution with the concentration of 0.1 mol/L under TEM. Subsequently, three environmental friendly AFFF formulations (F-1, F-2, F-3) were designed with the mixture of the fluorocarbon surfactant, sodium n-octyl sulfate and lauryl betaine BS-12 as foaming agent. Through its foam performance test, it could be seen that F-3 showed relatively excellent foam performance. The initial foam height h 0 was 70 mm, the 25% drainage time was 315 s, the extinguishing time was 28 s, and the burn-back time was 720 s. This kind of fire extinguishing agent had the potential of fire protection application.

“…A significant shift in corrosion potential from ∼−0.26 to ∼−0.06 V was also discovered. The results indicated that the composite SiO 2 @CTACe nanoparticles can adsorb onto the metal surface via the electrostatic interaction between cationic CTACe and copper ,, and generate a potent protective film that can effectively inhibit the water-induced electrochemical corrosions (Figure B). − Figure S16, SI, illustrates that the SiO 2 @CTACe particles can also serve as an effective corrosion inhibitor for metallic materials under ocean salinity (i.e., 3 wt % NaCl). One can see that, in contrast to the copper electrode immersed in saline, the one placed in the 4 mmol L –1 CTACe-containing Pickering emulsion displayed not only a pronounced reduction in corrosion current from ∼3.08 × 10 –6 to ∼8.9 × 10 –8 A cm –2 but also a positive shift in corrosion potential from ∼0.27 to ∼0.11 V. Figure S17, SI, indicates a good anticorrosive performance of the PDMS/water/SiO 2 @CTABr emulsion, as the copper immersed in it exhibited no sign of surface erosion.…”

“…In comparison to traditional oil-based lubricants, emulsion-type lubricants can provide both efficient lubrication and heat dissipation for mutually interacting metallic materials, , which can effectively prevent any damages from mechanical forces or the heat generated during the friction. Such properties are crucial for metalworking and heavy equipment lubrication. , Emulsions for metalworking usually require potent lubricative and anticorrosive performances to prolong the life of workpieces and tools. , For economical concerns, a metalworking emulsion is usually continuously used until it entirely loses its efficiency. Consequently, a long-term stability for a metalworking emulsion is also required.…”

Traditional industrial lubricating emulsions usually contain a variety of constituents to fulfill their functional requirements in long-term stability, lubrication, and anticorrosion. The complexity of the constituents may produce difficulties for their preparation, storage, and recycling. To address this issue, here we design and prepare simple-component, switchable, and multifunctional Pickering emulsions using the green lubricating base oil polydimethylsiloxane, water, and silica nanoparticles m o d i fi e d w i t h a s e r i e s o f m a g n e t i c s u r f a c t a n t s (C n H 2n+1 N + (CH 3 ) 3 [XCl 3 Br] − , n = 12, 14, and 16, X = Ce, Fe, and Gd) as compositions. The Pickering emulsions are demonstrated to be highly stable, lubricative, and anticorrosive. Their magneto-responsiveness indicates a potential application as smart lubricants. Their reversible emulsification and demulsification, which allows an effective recycling and reuse of the composite nanoparticles, can be regulated by alternative centrifugation and homogenization or successive addition of the anionic surfactant sodium dodecyl sulfate and the magnetic cationic surfactants. Both their stability and lubricity can be optimized by using surfactant C 16 H 33 N + (CH 3 ) 3 [CeCl 3 Br] − (CTACe) as the surface coating for the silica particles. The deposition of CTACe-modified silica nanoparticles endows a metallic material with a high resistance to abrasion and corrosion. We envision that such emulsions, consisting of eco-friendly, biocompatible, and low-cost materials, could find extensive applications in sustainable chemistry and engineering.

CALCULATION OF HYDROPHILIC-LIPOPHILIC BALANCE FOR THE SYSTEM OF 2,3-SUBSTITUTED-5,6-DIHYDRO-3H-[1,3]THIAZOLO[3,2-b][1,2,4]TRIAZOL-7-IUM

Cationic surfactants are widely used in industry, medicine, and in studies of a number of physicochemical processes. Analysis of the literature data indicates the high biological activity of cationic surfactants, particularly antimicrobial, antifungal, and in general biocidal. Currently, QSPR methods are increasingly used; they allow the prediction of properties based on the compound's molecular structure. One of the important parameters of cationic surfactants is the ratio of polar (positively charged "head") and non-polar (long hydrocarbon "tail") parts of their molecules. This ratio is called hydrophilic-lipophilic balance (HLB). In 1949, Griffin and Davis developed HLB scales of colloidal surfactants, according to which the HLB parameter can take values in the range from 1 (the substance is insoluble in water but soluble in nonpolar liquids) to 40 (the substance is soluble in water and insoluble in nonpolar liquids) conventional units. Given the complexity of the experimental determination of HLB, mathematical additive models for its calculation were developed. In our previous studies, methods for the synthesis of cationic 1,2,4-triazolium systems, including cationic surfactants based on 1,3-thiazolo-1,2,4-triazole condensed nucleus, were developed. Thus, 2,3-substituted-5,6-dihydro-3H-[1,3]thiazolo[3,2-b][1,2,4]triazol-7-ium were selected as model objects in this study. The construction of model compounds was performed in the Avogadro program with subsequent optimization of the geometry using the force field MMFF94. The HLB index was calculated by three methods: Griffin, Davis, and the ratio of polar and nonpolar areas on the isosurface of the molecule using the software package Vega ZZ. Simple approach for calculating HLB based on the number of carbon atoms in long alkyl substituents have been established. HLB values are the largest when calculating the ratio of polar and non-polar parts of the molecule. The calculated values of HLB vary in a wide range, which allows referring the investigated systems to emulsifiers "oil/water" (for short alkyl chains C1–C4), wetting agents (for short alkyl chains C1–C5), emulsifiers "water/oil" (for alkyl chains C5–C20), antifoams (for alkyl chains C18–C20).
