Physical property Under normal circumstances, ethylene is a colorless slightly odorous gas with a density of 1.256q, slightly less dense than air, difficult to dissolve in water, easily soluble in organic solvents such as carbon tetrachloride. Appearance and properties: colorless gas, slightly with a unique smell of hydrocarbons. A small amount of ethylene has a faint sweetness. Absorption peak: The absorption band is in the far ultraviolet region. Solubility: insoluble in water, slightly soluble in ethanol, ketone, benzene, ether. Soluble in organic solvents such as carbon tetrachloride. Ethylene source The main source of ethylene production is petroleum. Ethylene is an important chemical raw material, and its output is a symbol of the level of petrochemical industry in a country. The production of ethylene is mainly dependent on the processing of petroleum, including direct distillation of crude oil, secondary processing of distillates, and natural gas and oil field gas. These raw materials through chemical processing, can produce ethylene, and then used in synthetic fibers, synthetic rubber, synthetic plastics and other chemical products. Ethylene industry is the core of petrochemical industry Ethylene products account ...
