摘要：
Oil soluble polyethylene glycol (PEG-1500) diesters of stearic, 12-hydroxystearic, oleic and 12-hydroxy oleic (ricinoleic) acids were prepared by standard condensation reaction procedure. The surface active/emulsifying properties of the products were evaluated by determining interfacial tension and through performance test in making water-in-oil emulsion. The presence of double bond or hydroxyl group in the C//1//8 acids, PEG content of reacting mixture, and nature and concentration of the catalyst in preparing the emulsifier all were found to have great bearing on the emulsifying property and stability of w/o emulsions, particularly when the aqueous phase contained a significant quantity of ions. The first factor, the effect of double bond and/or the hydroxyl group, is discussed in this paper.
