实验性质
| 外观 / 形态 : | Ethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams.；CBI; Other Solid; Liquid；PEG 400 is a clear, viscous, colourless or almost colourless hygroscopic liquid; PEG 3000, PEG 3350, PEG 4000, PEG 6000 and PEG 8000 are white or almost white solids with a waxy or paraffin-like appearance；Clear, colorless, syrupy, odorless liquid. [antifreeze] [Note: A solid below 9 degrees F.]; [NIOSH]；Liquid；ODOURLESS COLOURLESS VISCOUS HYGROSCOPIC LIQUID.；Clear, colorless, syrupy, odorless liquid.；Clear, colorless, syrupy, odorless liquid. [antifreeze] [Note: A solid below 9 °F.]；Clear, colorless, syrupy (viscous) liquid at room temperature. Often colored fluorescent yellow-green when used in automotive antifreeze. |
