ЭТИЛ Н-ПРОПИЛ Эфир химические свойства, назначение, производство
Использование
Ethyl Propyl Ether (cas# 628-32-0) is used in the composition of methanol fuel for vehicles which solves the problems of vehicle methanol fuel meeting water and low temperature stratification, rubber swelling, metal corrosion, hot air resistance, and cold start.
Общее описание
A colorless liquid with an ether-like odor. Less dense than water. Flash point below 0°F. Vapors heavier than air. Used to make other chemicals.
Реакции воздуха и воды
Highly flammable. Soluble in water. Ethers tend to form unstable peroxides when exposed to oxygen. Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. Ether peroxides can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid.
Профиль реактивности
Ethers, such as ETHYL N-PROPYL ETHER, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
Угроза здоровью
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Пожароопасность
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Профиль безопасности
A slight inhalation
hazard. Very dangerous fire and explosion
hazard when exposed to heat or open flame.
To fight fire, use alcohol foam. When
heated to decomposition it emits acrid
smoke and fumes. See also ETHERS.
