“…Quaternary ammonium salts are the most widely used cationic surfactants and have been primarily synthesized from tertiary amines [13]. One-step amination has been a mature technology for producing tertiary amines from aliphatic alcohols [14].…”

A novel cationic surfactant Guerbet-cetyl trimethyl ammonium chloride (G-CTAC) was synthesized by combining several traditional synthetic processes in laboratory. The molecular structure of G-CTAC was characterized by Fourier transform infrared (FT-IR) spectra and proton nuclear magnetic resonance ( 1 HNMR). This new amphiphile exhibited excellent performances in aqueous solution, which was investigated by surface tension measurement, contact angle on parafilm, particle size of aggregates, transmission electron microscopy (TEM), emulsifying experiments, and antistatic tests. It was found that the new quaternary ammonium compound could effectively decrease the surface tension of aqueous solution to 26.2 mN m −1 with the critical micelle concentration (CMC) being 5.9 mmol L −1 . In addition, the cationic surfactant synthesized could efficiently decrease the contact angle of aqueous solution on paraffin surface. We suppose that these unique properties are attributed to the presence of the branching Guerbet-cetyl being hydrophobic group in the molecule. Moreover, according to TEM observations, this quaternary ammonium compound was inclined to aggregate into vesicles spontaneously without induction of any other additives in aqueous solution. Antistatic tests and emulsifying experiments were also conducted to explore the potential applications of this new material.

“…This explains the negative θ values and perhaps is in part of the origin of the positive values of diss S 0 for tetraalkylammonium salts [27]. It is likely that the θ values of tetraalkylammonium salts are more negative than the ones for the two macrocyclic aminals of this work, because the quaternary ammonium salts are more hydrophobic as their surface tension values in aqueous solution shows them to be surface active solutes [28][29][30]. Recently published values of surface tension of HMT aqueous solutions at 298.15 K in the entire range of solubility shows that values of ads G 0 are very near to zero [31,32], which indicates that the HMT molecule, and even more the TATD one, are more hydrophilic than quaternary ammonium salts.…”

Densities of several aqueous solutions of two macrocyclic aminals, 1,3,5,7-tetraazatricyclo[3.3.1.1(3,7)]decane (HMT) and 1, 3,6,8-tetraazatricyclo[4.4.1.1(3,8)]dodecane (TATD) at concentrations from 0.001 up to 0.2 mol·kg −1 (molal) between 2.0 and 5.0°C every 0.5°C, were obtained using a magnetic float densimeter designed, constructed and calibrated according to the available literature. The effect of the two solutes on the temperature of the maximum density of the water θ was established. The dependence of density with molality is linear in the entire range of concentration, at all temperatures, and the dependence of θ with composition, for both aqueous systems, does not follow the Despretz law. Based on the variation of θ with composition, the solutes are classified as liquid water structure breakers; the effect of TATD on the solvent is greater. The results are discussed in terms of solute-solvent and solute-solute interactions.

“…The highest values of pC 20 were observed for derivatives with two alkyl chains M 2 M-n. The values of pC 20 and, ipso facto, the efficiency of surface tension reduction in most cases increases with the growth of hydrophobicity of the molecule, which is obvious. It is worth noting that among the derivatives presented in Table 2 two surfactants: DMGAM-12 and DMALM-12 reveal strong biological activity.…”
