Ethylene glycol dimethyl ether

Ethylene glycol dimethyl ether Physical and chemical properties Appearance and characteristics: Colorless liquid with a slight ether odor. Relative density: 0.87 Relative vapor density: 3.11 Melting point: -69 Boiling point: 83 Concentration: Saturated vapor pressure of pure substance: 6.40 (20°C) Solubility: Soluble in water and hydrocarbons. Heat of combustion (kJ/mol): 2516.7 Critical temperature (°C): 362 Critical pressure (MPa): 3.87 Uses: Used as a solvent, pharmaceutical extractant, and intermediate in organic synthesis. Operation and Storage Operating precautions: Operate in a sealed environment with adequate ventilation. Operators must receive specialized training and strictly adhere to operating procedures. It is recommended that operators wear filter-type gas masks (half-masks), chemical safety goggles, anti-static work clothing, and oil-resistant rubber gloves. Stay away from flames and heat sources; smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the workplace air. Avoid contact with oxidizers and acids. During filling, the flow rate should be controlled, and a grounding device should be in place to prevent static electricity buildup. Handle with care during transportation to prevent damage to the packaging and containers. Equipped with appropriate types and quantities of fire-fighting equipment and emergency response devices for leaks. Empty containers may still contain harmful substances. Storage precautions: Usually, the product contains stabilizers. Store in a cool, well-ventilated warehouse. Keep away from flames and heat sources. The storage temperature should not exceed 30°C. The packaging must be sealed to prevent contact with air. It should be stored separately from oxidizers and acids; mixed storage is strictly prohibited. Use explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools that may generate sparks is prohibited. The storage area should be equipped with emergency response equipment for leaks and appropriate containment materials. Transportability: Hazardous goods code: 32093; UN number: 2252; Packaging marking: No information available. [Fire hazard] Peroxides may form upon long-term storage. It reacts violently with oxidizers and hydrides, as well as with lithium aluminum hydride (LiAlH4). It is prone to combustion and explosion when exposed to high temperatures or open flames. [Disposal methods] Water-resistant foam, carbon dioxide, dry powder, sand. Last edited by zxh6267 on 2009-2-12 at 11:59
