Synthesis and Characteristics of Dodecyl Isopropylolamine and Derived Surfactants

Abstract

Dodecyl isopropylolamine has been synthesized on the basis of dodecylamine and propylene oxide. The structure of dodecyl isopropanolamine has been determined by X‐ray diffraction, elemental analysis, IR‐ and NMR‐spectroscopic methods. Ionic surfactants have been synthesized by interaction of dodecyl isopropylolamine with various acids (HCl, HBr, acetic and propionic) and alkyl halides (methyl iodide, ethyl bromide and n‐propyl bromide). Colloidal‐chemical parameters, petroleum‐collecting and petroleum dispersing capacities of the synthesized cationic surfactants have been studied.

Synthesis and Properties of Quaternary Ammonium Surfactants Based on Alkylamine, Propylene Oxide, and 2‐Chloroethanol

“…For cationic surfactants based on ethanolamines and nonyl bromide, K max in seawater is 40.5 (Asadov, Nasibova et al, ), in the case of cationics formed by interaction of dodecyl isopropylolamine with various alkyl halides and acids—30.4 (Asadov, Rahimov et al, ), and for gemini cationic surfactants based on Guava fat—15.5 (Abo‐Riya, Tantawy, & El‐Dougdoug, ). As seen, K max for the synthesized quaternary ammonium surfactants is substantially higher than for similar cationic surfactants.…”

“…Petroleum‐collecting properties of the obtained surfactants (as is and 5% wt aqueous solutions) have been investigated using Pirallahy oil (the value of density at 20 °C—0.9244 g cm −3 ; the value of kinematic viscosity at 30 °C—1.05 cm 2 s −1 ) collected from a field near Baku (Azerbaijan) (Asadov, Rahimov et al, ; Asadov, Rahimov, Mammadova, Ahmadova, & Ahmadbayova, ). The sample (0.02 g) or its solution (also 0.02 g) was added to a thin film (thickness 0.16−0.17 mm) of the crude oil on the surface of distilled, fresh, and Caspian Sea water in separate Petri dishes.…”

“…Surface tension was measured by Du Nouy ring using a KSV Sigma 702 tensiometer (Attension Biolin Scientific, Finland) (Asadov, Rahimov, Mammadova, Gurbanov, & Ahmadova, 2017). The sample was introduced to a doublejacketed glass cell thermostated with a water bath.…”

Crystal structure and Hirshfeld surface analysis of 4-{2,2-dichloro-1-[(E)-(4-fluorophenyl)diazenyl]ethenyl}-N,N-dimethylaniline

“…Both inter-and intramolecular weak interactions play a crucial role in determining the properties of organic compounds and controlling their molecular organization in solution and in the solid state, which is sensitive to their chemical environment, solvent polarity, temperature, etc. (Asadov et al, 2016;Maharramov et al, 2009Maharramov et al, , 2010Mahmudov et al, 2013Mahmudov et al, , 2014aMahmudov et al, ,b, 2015Mahmudov et al, , 2017aMahmudov et al, ,b, 2019Shixaliyev et al, 2013Shixaliyev et al, , 2014. For example, in catalysis monomeric, oligomeric or polymeric compounds can promote various organic transformations not only by coordination bonds but also through non-covalent interactions, such as hydrogen, halogen, chalcogen, pnictogen, tetrel and triel bonds, as well as metal-metal, cation-, anion-, lone pair-,stacking, agostic, pseudo-agostic, anagostic, dispersion-driven, lipophilic, etc, or their cooperation (Akbari Afkhami et al, 2017;Gurbanov et al, 2017Gurbanov et al, , 2018Kopylovich et al, 2011a,b;Ma et al, 2017a,b;Mahmoudi et al, 2016Mahmoudi et al, , 2017aMahmoudi et al, ,b,c, 2018a.…”

“…are much weaker than covalent bonds. Nevertheless, they can control the reactivity of molecules, the crystal packing, tautomerization and other properties (Asadov et al, 2016;Mahmudov et al, 2019). For example, such kinds of weak interactions can create interesting supramolecular networks in coordination compounds, involving monomeric, oligomeric or polymeric subunits, which affects their catalytic activity (Afkhami et al, 2017;Gurbanov et al, 2018).…”
