2. Lintho tsa lik'hemik'hale: Ke joala bo mafura, bo nang le hydrophilic le lipophilic, 'me bo ka sebelisoa e le emulsifier le surfactant. E na le thepa ea ho thibela, e thusang ho laola le ho tsitsisa tekanyo ea acid-base. Li-dodecane diols le tsona ke thepa ea bohlokoa ea ho haha, solvent ea indasteri le lik'hemik'hale.

 

3. Mokhoa oa ho itokisa: Ho lokisoa ha li-dodecane diol hangata ho fumanoa ka hydrododecane aldehyde reaction. Karabelo ena e susumetsa substrate dodecanealdehyde e nang le hydrogen, ka boteng ba "catalyst" e nepahetseng, ho hlahisa li-dodecane diols.
