物理形态与操作说明

  • 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]
