| 摘 要： | 本文用核磁共振法研究了制剂中常用的 Span 类与 Tween 类以及混合时 HLB 值的测定,建立了求算 HLB 值的方程式:HLB=18.24R+1.80,式中 R=(ΣH_((W))/(ΣH_((W))+ΣH_((0))),该式对此类单一的和混合的非离子表面活性剂都适用。此方法快速,无破坏性,需样品量少。

| Abstract: | In this paper,the hydrophilic-lipophilic balance(HLB)values have been studied by means of NMR and the equation of calculating the HLB values has been founded:HLB=18.24R+1.80,where R=∑H(w)/∑H(w)+∑H(o).This equation is available not only to the single nonionic surfactants,but also to the mixed ones.The method is rapid,nondestructive and requires only small samples. The results are in good agreement with given HLB values. |
