| Specifications | |
|---|---|
| Description: | A clear, colourless, viscous liquid; practically odourless; hygroscopic. |
| Solubility: | Miscible with water, with ethanol (95%) with acetone and with chloroform. |
| Identification A (By IR): | IR spectra of the sample should be concomitant with IR spectra of the standard |
| Identification B (Diethylene glycol): | NMT 0.1% |
| Identification B (Ethylene glycol): | NMT 0.1% |
| Identification C (By GC Chromatogram): | The retention time of the propylene glycol peak of the sample solution corresponds to that of the standard solution |
| Acidity: | Not more than 0.2mL of 0.1 M sodium hydroxide should require to change the colour of the indicator to original pink. |
