Appearance/Description: | Clear, colourless, slightly viscous oily liquid, Fatty odour not more intensely coloured than reference solution Y6 |
Solubility: | Soluble in water, miscible with ethanol (96%), toluene alcohol, ether, and with chloroform |
Boiling point: | About 260°C. |
Identification (By IR): | IR spectra of the sample should be concomitant with IR spectra of the corresponding standard. |
Identification (By GC): | The retention time of the triacetin peak of the sample solution corresponds to that of the standard, as obtained in the assay. |
