Ethylene oxide Safety Data Sheet P-4798 This SDS conforms to U.S. Code of Federal Regulations 29 CFR 1910.1200, Hazard Communication. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. The lower the flash point, the easier it is to ignite the material. Vapor Pressure. Ethylene can polymerize at low pressure if catalyzed by titanium halides. However, even at the higher ethylene glycol concentrations, coolant liberated from an • As a reactant in the preparation of dimethyl carbonate, glycerol carbonate by transesterification … SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam.

CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. 350°F, has an auto-ignition temperature of around 750°F, and a flash point of around 260°F. helps to ensure delivery of ethylene glycol and diethylene glycol when and where you need it. Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Solubility. ethylene oxide and compoundscontaining labile hydrogen atoms; therefore, such compounds are often used to produce derivatives. Ethylene - Thermophysical Properties - Chemical, physical and thermal properties of ethylene, also called ethene, acetene and olefiant gas. However, an essential difference is that ethylene oxide is fully miscible with water.

LARGE FIRE: Water spray, fog or alcohol-resistant foam. Ethylene glycol is a clear, colorless syrupy liquid. Ethylene glycol may be used in the preparation of spiroborate esters by reacting with chiral 1,2-aminoalcohols in the presence of triisopropyl borate. It is very water soluble and solutions of as little as 4% in water are flammable. Ethylene in the presence of aluminum chloride may undergo a violent reaction [J. Inst.
