OSTI ID:6325451
During the past year we have continued three major projects: (I) further delineation of surfactant adsorption mechanisms, (II) the systematics of chromatographic separation processes, and (III) the design and evaluation of surfactants. In I we have: (a) explored surface condensed structures and plateau adsorption levels; and (b) expanded absorption theory to encompass heterogeneities, studied the critical admicelle concentration and multicomponent adsorption. In II we have traced the composition path for several pure alkyl benzene sulfonates in the grid diagram and examined surfactant wave fronts. In III we have developed two and quantitative surfactant synthesis schemes and finished studies on ..cap alpha..-olefin sulfonates, ethoxylated oleyl sulfonates and alkane sulfonates. The following 5 papers in III have been processed for inclusion in the Energy Data Base: (1) synthesis and performance of isomer-free secondary alkane sulfonate surfactants; (2) synthesis and performance of linear monoisomeric ethylene oxide sulfonate surfactants; (3) alpha-olefin sulfonates for enhanced oil recovery; (4) ethoxylated oleyl sulfonates as model compounds for enhanced oil recovery; (5) phase behavior of simple salt tolerant sulfonates.
