摘要
本文研究了混合表面活性剂中碳链长度差别和双键对微小乳状液形成温度影响。发现碳链长度差别和双键均可使微小乳状液自发形成温度下降，二者同时存在可使乳化温度降得更低。提出了不太紧密的混合膜可能有利于微小乳状液自发形成的观点。
The effect of the difference in the HC chain length and the double bond(in the HC chain)of the mixed surfactants on the temperature of miniemulsion for-mation were studied. For the systems studied in this work,the greater the difference in the HC chain length of the mixed surfactants, the lower the temperature of the miniemulsion formation。 The presence of the double bond in the surfactant HC chain may also depress the temperature of miniemulsion formation。The formation temperature of miniemulsions can be depressed to even Iower in the case of coexi-tence of the above-mentioned two factors.A viewpoint was proposed that the mixed film with less compactness was favorable to the formation of miniemulsions。
