Synthesis and Characterization of Glucosamide Surfactant

Abstract

The synthesis and structural analysis of glucosamide surfactants of the general formula C n H 2n?1 NH(CH 2 ) 2 NHCO(CHOH) 4 CH 2 OH (n = 8, 10, 12) are described, and the surface activity properties of the surfactants are studied. N-alkylethylenediamines were synthesized by the alkylation of the ethylenediamine with alkyl bromide. The glucosamide surfactants, N-alkyl-N 0 -glucosylethylenediamine (C n GA), were prepared by amidation of the precursor diamine with D-gluconic acid d-lactone. They were structurally characterized by IR, 1 H NMR and MS. They reduced the surface tension of water to approximately 26-27 mN m -1 at concentration levels of (0.5-1.6) 9 10 -3 mol L -1 .

Biosurfactant Derived from Fenugreek Seeds and Its Impact on Wettability Alteration, Oil Recovery, and Effluent Treatment of a Rock System of Mixed Composition

“…An IFT value of 10 mN/m at 0.2 wt % was found to be the minimum as thereafter, IFT exhibited a constant trend and barely showed any variation till the concentration of the surfactant was explored (0.5 wt %). The trend of reducing IFT with increase in surfactant concentration has been also reported in the literature. , The point, where the IFT curve showed a constant trend despite increasing the surfactant concentration, is said to be the CMC value of the surfactant, consistent with the research findings in the literature . It is expected that the oil–water interface is saturated by surfactant micelles at the CMC, and above CMC, these micelles prefer to stay in the bulk liquid phase .…”

Amphoteric and cationic surfactants for enhancing oil recovery from carbonate oil reservoirs

“…Nowadays because of the soaring tendency of countries to energy use and the subtractive of the new oil fields (greenfield) discoveries, there is a crucial need of technological methods to re-expand the oil fields to reinforcement at the reservoir condition [1][2][3][4]. The rate of exploitation of different trapped sorts of fossil resources affects common energy requisition [5][6][7][8][9]. Although the high amount of oil is exploited daily, approximately thirty percent of the oil reserves have been produced by natural drive mechanisms of oil recovery techniques [10][11][12][13][14][15].Thus, enhanced oil recovery (EOR) methods can exploit the extra oil [16][17][18][19] because the remaining trapped oil is a huge and charming target for EOR techniques in petroleum industry [20][21][22][23][24].…”

Synthesis of Glucose-Modified Siloxanes by a Simplified Procedure

“…A great variety of carbohydrate-modified siloxane surfactants have been prepared by Wagner and colleagues (3)(4)(5)(6)9). An alternative is the ring-opening reaction between an amino-functional siloxane and a carbohydrate lactone (9,(13)(14)(15), but other methods have also been used and are still developed (1,12,(16)(17)(18).…”
