The surfactant have been synthesized by the reaction of propylene glycol(PG)、tripropylene glycol(TPG) 、polypropylene glycol (PPG M.W. =700, 1000)、triethyl orthoformate (TEOF) and polyoxyethylene stearyl ether. FTIR, 1H-NMR and element analysis have been used to confirm the structure of these compounds. We used buffer solution pH=4,7,10 to observe the degradation of products under acidic, neutral or alkaline conditions. The structure change of these cleavage products was confirmed by FTIR analysis. The fundamental surface activity including surface tension, contact angle, foaming and emulsifying power was studied. Keng-Ming Chen 陳耿明 2006 學位論文 ; thesis 87 zh-TW |
