New cocogem surfactants were synthesized by interaction of dodecylisopropylol amine with dicarboxylic (oxalic, succinic, adipic, sebacic, tartaric, maleic, fumaric, isophthalic) acids. By tensiometric method, the surface activity aqueous solutions at border air was studied and, conductometric specific electrical conductivity these determined. The degree counterion binding (β), critical micelle concentration (CMC), effectiveness tension reduction (πCMC), excess (Γmax), area per molecule...
Abstract Octyl amine, nonyl dodecyl hexadecyl amine and octadecyl are propoxylated with propylene oxide at mole ratios 1 : 2. The structure of the synthesized compounds has been identified by IR-and NMR-spectroscopy methods. Colloidal-chemical indices these have also determined their surface-active parameters measured, including critical micelle concentration (CMC), effectiveness surface tension reduction (π CMC ), excess (Γ max area per molecule interface (A min changes Gibbs free energies...
AbstractThe influence of counterions on the surface properties N-lauryl diisopropanolamine surfactants is delineated using conductometry and tension measurements. Twelve types organic have been studied: C1–C12 monocarboxylic acids anions. The synthesized surfactants, including tension, critical micelle concentration (CMC), effectiveness (πCMC), efficiency (pC20), maximum excess (Γmax), minimum area (Amin), Gibbs energy micellization (ΔGmic), adsorption (ΔGad) processes in aqueous....
Liquid-phase aerobic oxidation of naphthene-paraffinic hydrocarbons at 217-330о С diesel fraction Balakhany oils in the presence mixtures Mn, Cr salts natural petroleum acids (MeNPA) has been investigated. The catalytic process is realized for 7 hours temperature 135-1400C a barbotage reactor. Samples were taken every hour and oxidized product was separated by composition accordance with known methods. Mechanism studied IR- spectroscopy. It found that, after 5 yield obtaining synthetic rich...
N-Methylethylolamides have been synthesized on the basis of vegetable oils (corn, coconut, canola, olive, cotton-seed, and palm) modified with orthophosphoric acid. The structure N-methylethylolamides their phosphate derivatives has identified by IR NMR spectroscopies. Surface activity at water–air border determined colloidal-chemical parameters (maximum surface excess concentration minimum area per molecule aqueous solution–air interface, pressure critical micellization (CMC), standard...
The paper deals with the liquid-phase aerobic oxidation of naphthene-paraffinic hydrocarbons separated from distillate transformer oil T-1500, a mixture Azerbaijani oils.Reduced graphene oxide was used as reaction catalyst.The purified aromatic by sulfonation before process.The number in fraction ~1% after sulfonation.By spectral analysis methods, physicochemical properties fractions and process were determined, their structural group composition studied.The catalyst obtained wellknown...
The interaction of soybean oil triglycerides with hexamethylenediamine resulted in a nonionic surfactant – hexamethyleneamide mixture acids, which was then modified using alkyl dihalides (1,2-dibromoethane, 1,3-dibromopropane, and 1,5-dibromopentane). These reactions synthesized ionic surfactants. composition structure the resulting amidoamine its modifications were identified infrared spectroscopy. obtained products characterized by key physicochemical parameters. Conductometric...
