摘要
本文用苯酚滴定法研究了酯类对吐温80,40,20亲水亲油平衡值的影响。结果表明:乙酸乙酯、乙酸甲酯均使上述三种表面活性剂的亲水亲油平衡值降低,而乳酸乙酯则使之升高。本文还对上述结果的原因进行了简要讨论。
In this paper,the effect of various esters on HLB value of tween 80,40,and 20 has been studied by the phenol titrimetric method,The results indicate that methyl acetate and ethyl acetate decrease HLB values of tween 80,40 and 20,but ethyl lactate increases HLB values of them.
