Monoethylene Glycol ( MEG )

Description Monoethylene Glycol (MEG) is a colorless, virtually odorless and slightly viscous liquid. It is miscible with water, alcohols, aldehydes and many organic compounds. MEG will not dissolve rubber, cellulose acetate or heavy vegetable and petroleum oils. MEG has a low volatility and it is 50% more hygroscopic than glycerol at room temperature.    Ethylene Glycol Specification Purity % 99.9 Color, (Pt-Co)(No. before heated) ≤addition of acid (heated) ≤ 520 Density, (20)g/cm3 1.1131-1.1136 Water, %(m/m) ≤ 0.05 Boiling range (0.0.10133MpaInitial point ≥Dry point ≤IBP-DP 196-2 Acidity (calculated as), % (m/m) ≤ 0.001 (calculated as formaldehyde), %(m/m) ≤ 0.0008 Iron calculated as Fe2+), % m/m) ≤ 0.00001 Ash, % (m/m) ≤ 0.002 DEG and TEG, % (m/m) 0.1 Chlorine (calculated as chlorine ion), % (m/m) 0.00005 Ultraviolet transmittance %220nm ≥275nm ≥350nm ≥ 709098     Main Parameter Allowances Determined Value Appearance Colorless, transparent, syrupy liquid Colorless, transparent, syrupy liquid Purity (%) ≥99 99.5 Hazen before heating ≤5 5 Hazen after heating with HCL ≤20 10 Density at 20 °C(g/cm³) 1.1128-1.1138 1.1135 Initial boiling point at 0°C,10133MPa(°C) ≥196 197.6 Dry point at 0°C,10133MPa (°C) ≤199 198.6 Moisture (%) ≤0.10 0.0356 Acidity (as acetic acid %) ≤0.001 0.0006 Fe assay (mass fraction %) ≤0.00001 0.000004 Ash (mass fraction %) ≤0.001 0.0008 Diethylene glycol(%) ≤0.10 0.034 Aldehyde (as methanal %) ≤0.0008 0.0002 UV transmittance at 220nm (%) ≥75 86.5 UV transmittance at 275nm (%) ≥92 99.5 UV transmittance at 350nm (%) ≥99 99.9   Ethylene Glycol Application  1. Freeze protection, heat transfer and hydraulic fluids; Natural gas  And hydrocarbon treating agents;  2. Hydroscopic agents for paper, cork and textile conditioning;  3. Plasticizer formulations and raw materials for ester and  Polyester production.  4. The ethylene glycol family's solvency properties are useful
