“…Yet, the best retention (above 95.8%) is obtained by the 10 CMC CG surfactant and 1 mM phenol solution. The size of micelles studied herein is in the order of CG > SDS > DTAB > Brij35, in accordance with their aggregation number [24,[26][27][28]. Because the aggregation number of surfactant is an indicator of the size of micelles [24].…”

“…All of these syntheses are based on the nucleophylic attack of a tertiary amine to the carbons of 1,3-DCH supporting the chlorine atoms. The presence of a hydroxyl in the spacer group confers tuneable properties to these compounds [222,223].…”

Crude glycerol (C3H8O3) is a major by-product of biodiesel production from vegetable oils and animal fats. The increased biodiesel production in the last two decades has forced glycerol production up and prices down. However, crude glycerol from biodiesel production is not of adequate purity for industrial uses, including food, cosmetics and pharmaceuticals. The purification process of crude glycerol to reach the quality standards required by industry is expensive and dificult. Novel uses for crude glycerol can reduce the price of biodiesel and make it an economical alternative to diesel. Moreover, novel uses may improve environmental impact, since crude glycerol disposal is expensive and dificult. Glycerol is a versatile molecule with many potential applications in fermentation processes and synthetic chemistry. It serves as a glucose substitute in microbial growth media and as a precursor in the synthesis of a number of commercial intermediates or fine chemicals. Chlorinated derivatives of glycerol are an important class of such chemicals. The main focus of this review is the conversion of glycerol to chlorinated derivatives, such as epichlorohydrin and chlorohydrins, and their further use in the synthesis of additional downstream products. Downstream products include non-cyclic compounds with allyl, nitrile, azide and other functional groups, as well as oxazolidinones and triazoles, which are cyclic compounds derived from ephichlorohydrin and chlorohydrins. The polymers and ionic liquids, which use glycerol as an initial building block, are highlighted, as well.

“…As these surfactants have superior properties with regard to conventional surfactants, numerous Gemini surfactants with different chemical structures have been synthesized and analyzed (Menger and Keiper, ; Rosen and Tracy, ; Zana, ). They exhibit interesting physical–chemical properties; for instance, they have lower CMC and higher surface activity than their parent monomeric counterparts (Tehrani‐Bagha et al, ; Wani et al, ). These surfactants attract interest of the researchers in the field.…”

N,N′‐bis [3‐(dodecanoylamino)propyl]‐N,N,N′,N′‐tetramethylhexane‐1,6‐diaminium dibromide is a cationic Gemini surfactant including quaternary ammonium salt with amide groups. Critical micelle concentration (CMC) and some thermodynamic parameters of the cationic Gemini surfactant were investigated using surface tension and conductivity methods. Mixed micellization of binary mixtures of the cationic Gemini surfactant with a conventional surfactant cetyl trimethylammonium bromide (CTAB) was investigated using the conductometric method at five different temperatures ranging from 303.15 to 323.15 K. CMC, micellar ionization degree (αm), counterion binding constant (g1), interaction parameter (β), and activity coefficients (f1M and f2M) of mixed systems were found out from data of conductivity at different mole fractions for all studied temperatures. Additionally, the effects of some inorganic salts with different concentrations on the surface properties of cationic Gemini surfactant were examined by surface tension measurements. Some surface properties of the pure cationic Gemini surfactant and mixed salts systems were calculated using the data of surface tension.
