MEG - Chemicals Products

PROPERTIES:Mono Ethylene 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. Description: Formular: HOCH2CH2OH CAS No.: 107-21-1 HS Code: 2905310000 Molecular Weight: 62.08 Specifications: Index content Purity (Ethylene Glycol) % 99.0 min Diethylenglycol % 0.05 max Iron ppm 0.1 max Water, % 0.1 max Color 10 max Ash Content ppm 10 max Specific Gravity (at 20/20?C) 1.1150 to 1.1158 Distillation at 760mm Hg 195-199?C Applications: MEG is mainly used in the production of polyester, polyethylene terephthalate (PET) and antifreeze solutions. It is an important dehydrating agent, good humectant and an industrial solvent. Packing, Storage and Handling: Packed in 230kg plastic drums, 18.4MTS into one 20??CL. Or in Flexitanks, 20MTs per tank. MEG is stored and shipped in stainless steel tanks (or in ordinary steel drums/tanks with epoxy resin coating) to avoid iron contamination. Where contamination by iron is desirable, metal in contact with the glycol should be aluminum or stainless steel (type 304/316). If contamination by halides is undesirable, the packing of the valves and the gaskets should be made of asbestos or other halide-free materials. Also, an inert gas (nitrogen) blanketing should be maintained to avoid oxygen contact which is a main course of U.V. deterioration.
