Synthesis of Cleavable Aryl Sulfonate Anionic Surfactants and a Study of their Surface Activity
Jul 01, 2008; Chen, Lin; Hu, Zhiyong; Zhu, Hailin; Xue, Zhuanru ... Abstract A series of cleavable aryl sulfonate anionic surfactants were synthesized from cyanuric chloride, aliphatic amine and H-acid mono sodium salt. Their structures were identified by ^sup 1^H NMR, Infrared Spectrum (IR) and Elementary Analysis (EA). Their critical micelle ...
Analysis of Minor Products in Linear Alkylbenzene Sulfonation. Comparison Between the Traditional Gravimetric Method and High Performance Liquid Chromatography (HPLC) Procedures Versus High Temperature Gas Chromatography (HT-GC)
Jul 01, 2008; Bengoechea, C; Fernández, A ... Abstract During the sulfonation process of the linear alkylbenzene (LAB) other products like sulfones and anhydrides are also formed in addition to the linear alkylbenzene sulfonic acid (HLAS). Most of them are transformed in different degrees during the aging and hydrolysis steps of the ...
A Study of the Technical Route of the Synthesis of Alkylbenzenes for Use as an Oil Displacement Agent
Jul 01, 2008; Dai, Xihai; Suo, Jishuan; Duan, Xia; Bai, Ziwu; Zhang, Li ... Abstract This paper describes the technology of synthesizing alkylbenzenes containing C^sub 16-19^ alkyl chains. The heavy alkylbenzenes were prepared by C^sub 16-19^ liquid paraffin dehydrogenation, followed by alkylation with benzene. A novel catalyst containing Pt and Sn as its main ...
Microemulsion Formation and Detergency with Oily Soil: IV. Effect of Rinse Cycle Design
Jul 01, 2008; Tanthakit, Parichat; Chavadej, Sumaeth; Scamehorn, John F; Sabatini, David A; Tongcumpou, Chantra ... Abstract The objective of this work was to apply a microemulsion-based formulation for the removal of motor oil in laundry detergency at low salinity. To produce the desired phase behavior, three surfactants were used: alkyl diphenyl oxide disulfonate (ADPODS), sodium dioctyl ...
Synthesis and Characterization of some Alkyl Polyglycosides Surfactants
Jul 01, 2008; El-Sukkary, M M A; Syed, Nagla A; Aiad, Ismail; El-Azab, W I M ... Abstract Alkyl polyglycosides (APGs) of different hydrocarbon chain lengths were prepared using an indirect method involving the condensation of fatty alcohol with dextrose. The chemical structures of the prepared compounds were confirmed using different spectroscopic techniques, ...
Syntheses and Characterization of Some Cationic Surfactants
Jul 01, 2008; Shehata, H A; El-wahab, A A Abd; Hafiz, A A; Aiad, I; Hegazy, M A ... Abstract A series of novel cationic surfactants were synthesized from the quaternization of triethyl amine and various long chain alkyl halide. The chemical structure of the prepared compounds was confirmed using elemental analysis, FTIR and ^sup 1^H-NMR spectra. The physical properties ...
The Characteristic Curvature of Ionic Surfactants
Jul 01, 2008; Acosta, Edgar J; Yuan, Jessica Sh; Bhakta, Arti Sh ... Abstract Characterizing the hydrophilic-lipophilic nature of a surfactant molecule has been a challenge for colloid scientists and technologists. The hydrophilic-lipophilic balance (HLB), the packing factor, the phase inversion temperature (PIT) and the natural curvature of the ...
Effect of Selected Nonionic Surfactants on the Activated Sludge Morphology and Activity in a Batch System
Jul 01, 2008; Liwarska-Bizukojc, E; Drews, A; Kraume, M ... Abstract In this study, two nonionic surfactants, one alcohol ethoxylate (AE) and one alkylphenol ethoxylate (APE) were investigated with regard to their influence on the morphology of activated sludge flocs, microbial activity and wastewater treatment efficiency in a laboratory batch ...
Synthesis and Performance Properties of Cationic Fabric Softeners Derived from Different Fatty Acids and 1(2-Hydroxyethylpiperazine)
Jul 01, 2008; Mishra, Shilpi; Tyagi, V K ... Abstract Quaternary ammonium salts (otherwise known as "quats") commonly form the foundation of formulations in the antimicrobial industry. Many studies have been conducted on the biological activity of surfactants derived from fatty acids viz. lauric acid, myristic acid, stearic acid ...
Preparation and Application of Fluorinated Cationic Surfactants
Jul 01, 2008; Mohamed, M Z ... Abstract Four fluorinated cationic surfactants were prepared by condensing 2,2,3,3, tetrafluoro-1-propyl chloroacetate with stoichiometric amounts of pyridine, 2-hydroxypyridine, 8-hydroxyquinoline and 8-hydroxyquinaldine to produce four quaternary ammonium salts. The surface and ...
