The unusual solution behavior of a series of N-alkyl-2-pyrrolidones has been exploited for efficient flocculation of hydrophobic and hydrophilic particles in aqueous dispersions. These pyrrolidones are surface-active low vapor pressure solvents of in

The phase behavior of N-cyclohexyl-2-pyrrolidone and a homologous series of N-alkyl-2-pyrrolidones mixed with water or with paraffins has been studied, and the effect of additives investigated. Depending upon the alkyl chain length, concentration, an

The properties of aqueous solutions of poly(maleic acid/octyl vinyl ether), PMAOVE, were studied by pyrene solubilization and fluorescence, solution viscosity, and phase separation induced by inorganic salts. The results indicate the existence of hyd

The interaction of poly(vinyl caprolactam) (PVCAP) with sodium dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) in aqueous solutions has been studied systematically by measuring the phase separation temperature, hydrodynamic radius,

The aggregation of N-cyclohexyl-2-pyrrolidone (CHP) in aqueous solution and its adsorption at the air–solution interface were investigated using surface tension, pyrene solubilization, fluorescence, viscosity, freezing point, light scattering and c

Diclofenac potassium 25mg (Cataflam®, Novartis New Zealand Limited) was reclassified from prescription medicine to pharmacist-only sale in New Zealand in 1992. This paper discusses methodological issues in postmarketing surveillance of Cataflam. Con

Purpose - Postmarketing surveillance of prescription medicines is a routine practice, yet similar evaluation of non-prescription medicines, including those recently switched from prescription status, is uncommon. This study presents the methodologic

The aggregation and surface activity ofN-butyl-2-pyrrolidone (BP) in water is investigated using surface tension, solubilization, fluorescence and NMR methods. The micelle point is high (-1.0 M) as expected for the butyl chain length, and the aggrega

While nonaqueous liquids are widely used commercially, the interfacial chemistry of nonaqueous liquid/liquid systems has received scant attention. In this paper interfacial properties of partially miscible two-component systems ofn-hexadecane with 2-
