Available in PDF, EPUB and Kindle. Book excerpt: Thermodynamic properties and aggregation behaviour of mixed micellar systems, comprised of sodium alkylcarboxylate salts, CnNa (where n = 8,10,12), ethoxylated alcohols, C4EOx (where EO = ethylene oxide group, X = 0,1,2,3,4), and n-alkyltrimethylammonium bromide salts, RNMe3Br (where R = octyl, decyl, and dodecy), have been studied to characterize the micellization process of the surfactants and to explore the specificity of interactions that lead to distinctive solubilization behaviour of polyethylene alkyl ether compounds in anionic and cationic micelles. The changes in the apparent molar properties of the surfactant in the monomer state, YSÓ, S, and in the micellar state, YMÓ, S; the distribution coefficient of the alcohol, KD between the micellar and aqueous phases; the change in the partial molar properties of the alcohol, Ø YMAS, and alcohol, NA?sub, in the mixed micelle, have been correlated with the chemical structure of the surfactants and alcohols. The apparent molar volumetric properties of the binary aqueous surfactant systems were analyzed using a mass-action model, which provides a quantitative description of the surfactant micellization process. The volumetric transfer functions for C4EOX, Ø YA(W · W + S), at a low concentration of 0.05 m (0.02 m in long chain surfactant systems), from water to the micellar phase were analyzed using a chemical equilibrium model to obtain the solubilization parameters of the alcohol in the micellar system, namely, the distribution coefficient, KD, and the change in the partial molar properties of the alcohol, Ø YMA, between water and the micellar phases. The mean aggregation number, NS?sub, of Csub8Na and Csub10Na in the mixed micelle, obtained from fluorescence quenching measurements, remains unc.

Download or read book Surfactants from Renewable Resources written by Mikael Kjellin and published by John Wiley & Sons. This book was released on 2010-01-26 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most modern surfactants are readily biodegradable and exhibit low toxicity in the aquatic environment, the two criteria for green surfactants. However the majority are synthesised from petroleum, so over the past decade the detergent industry has turned its attention to developing greener routes to create these surfactants via renewable building blocks. Surfactants from Renewable Resources presents the latest research and commercial applications in the emerging field of sustainable surfactant chemistry, with emphasis on production technology, surface chemical properties, biodegradability, ecotoxicity, market trends, economic viability and life-cycle analysis. Reviewing traditional sources for renewable surfactants as well as recent advances, this text focuses on techniques with potential for large scale application. Topics covered include: Renewable hydrophobes from natural fatty acids and forest industry by-products Renewable hydrophiles from carbohydrates, amino acids and lactic acid New ways of making renewable building blocks; ethylene from renewable resources and complex mixtures from waste biomass Biosurfactants Surface active polymers This book is a valuable resource for industrial researchers in companies that produce and use surfactants, as well as academic researchers in surface and polymer chemistry, sustainable chemistry and chemical engineering.

Book excerpt: Colloidal Surfactants: Some Physicochemical Properties focuses on the study of surface active agents. This book elaborates the importance of surface active agents in detergency, textile industry, and biological research. The four distinctive features of the substance—moderate maximum concentration of molecularly dispersed species; surface and interfacial depression in very dilute solution; micelle formation above a certain concentration; and solubilization of water-insoluble substances by micelles, are also described. Other topics include the effect of molecular type on the critical micelle concentration, critical micelle concentration, interaction of paraffin chain electrolytes with colloids, and monolayer studies of surface active agents. This publication is suitable for chemists and specialists researching on colloidal surfactants.

This book contains a thorough discussion of surfactant types and gives information of main routes of preparation. A chapter on novel surfactants has been included in the new edition. Physicochemical phenomena such as self-assembly in solution, adsorption, gel formation and foaming are discussed in detail. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface active polymers are presented and their interaction with surfactants is a core topic of the book. Protein-surfactant interaction is also important and a new chapter deals with this issue. Microemulsions are treated in depth and several important application such as detergency and their use as media for chemical reactions are presented. Emulsions and the choice of emulsifier is discussed in some detail. The new edition also contains chapters on rheology and wetting. Surfactants and Polymers in Aqueous Solution is aimed at those dealing with surface chemistry research at universities and with surfactant formulation in industry.
