21. Effects of a Novel Amphiphilic Graft Copolymer on Ternary Mixtures of Surfactant, Water, and Oil
Sammanfattning : An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. LÄS MER
22. Green Colloid Chemistry: Characterization of Environmentally Friendly Nonionic Surfactant Systems
Sammanfattning : Phase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. LÄS MER
23. Alkylglucosides - physical chemical properties
Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER
24. Novel Gemini Surfactants Based on Natural Products Aggregation Behaviour in Aqueous Solutions
Sammanfattning : There is currently much interest in using natural products to obtain novel types of surfactants. One of the reasons for increasing the proportion of surfactants based on natural products and replacing products based on petroleum raw materials is the growing concern about the environment. LÄS MER
