| Abstract | ||||
| A novel five series of monoesters were prepared two series by reaction of oxypropylated 1, 6 hexane diol with two types of fatty acid chloride (lauroyl and palmi and three series by the reaction of polyethylene glycol (MWs = 400, 1500, 2000) with three types of fatty acid chloride (decanoyl, lauroyl and palmitoyl chloride)]. The unique structural features of these surfactants were confirmed by spectroscopic tools (IR- 'H NMR). These nonionic monoesters have been found to exhibit excellent surface active properties including surface tension, interfacial tension, critical micelle concentration (CMC), low foaming, emulsion stability, and wetting. Also good biodegradability in river water, stability to hydrolysis in acidic and alkaline media, solubilization and dispersant properties in disperse dye systems were determined and evaluated. The antimicrobial and antifungal properties of these prepared monoesters were measured and evaluated .A comparison studies were done between the chemical structures and surface properties of such compounds. | ||||
