摘要： 研究了醇对非离子型表面活性剂浊点的影响,发现直链醇的碳原子数小于4时随着其在表面活性剂中含量的增加浊点上升;当碳原子数大于4时,则随着醇含量的增加浊点下降。醇的构型对浊点起着重要作用。

关键词: 浊点, 非离子型表面活性剂, 直链醇, 支链醇

Abstract: The solution of straight chain alcohols made the cloud points of Triton X-100 system increase if the number of alcohol carbon nc<4, and decrease if nc≥4. The longer the chain of straight chain alcohol, the stronger the effect on the cloud point. When the branch chain alcohols were added in the Triton X-100 system, the less the space resistance and the solubility of branch chain alcohols, the lower the cloud points of Tirton X-100 system. The effect of alcohols on the cloud points of Triton X-100 was related to the hydrophilicity and space structure of alcohol and solubilization position in the micelle.
