cyclohexene usage and synthesis

cycloolefin	cyclohexene is a cyclic olefin, and is a colorless, flammable liquid with a special pungent odor at room temperature. long-term placement in the air it can be oxidated into peroxide by air. naturally present in coal tar, soluble in acetone, carbon tetrachloride, benzene, ether, hexane, ethanol and other organic solvents, can form binary azeotrope with lower alcohols, acetic acid, etc. cyclohexene has the general nature of olefin, decomposes rapidly in the presence of uranium salts under sunlight or ultraviolet rays, is constant as being heated in a sealed tube at 200 ℃ for a long time, forms benzene and naphthalene at 400~500 ℃. it is obtained by dehydration of cyclohexanol at high temperature in the presence of an acid catalyst in industrial. it is obtained by sulfated dehydration of cyclohexanol in the laboratory. figure 1 is the chemical reaction equation of sulfated dehydration of cyclohexanol to obtain cyclohexene. cyclohexene is an important chemical raw materials, used for the production of adipic acid, adipic aldehyde, maleic acid, cyclohexane acid, cyclohexane aldehyde, maleic acid, cyclohexyl carboxylic acid, cyclohexanecarboaldehyde in industry. it is also used as the extraction agent, the stabilizer having a high-octane gasoline. inhalation can cause mild poisoning. here are some of these important compounds prepared by cyclohexene, (1)chlorinated cyclohexane is made, useful as pharmaceutical intermediates, a solvent and rubber additives. (2) cyclohexanone is made from cyclohexene, can be used as intermediates raw materials of medicine, pesticides, perfumes, and dyes, as polymer modifiers. (3) cyclohexyl acetate is made, used as a plastic solvent. (4) cyclohexanone phenol is made, can be used as raw materials medicine and pesticides. (5) aminocyclohexanol is made, can be used as surfactants and emulsifiers. (6) the product can also be used directly as organic intermediates, solvents and additives when spices are prepared. it can be used in the preparation of butadiene in the laboratory. the above information were edited and collated by yan yanyong of chemicalbook.
chemical properties	colorless flammable liquid. insoluble in water, soluble in ether.
usage	1. used in organic synthesis, it is also used as a solvent. 2. it is used as organic synthetic raw materials, such as synthetic raw materials for lysine, cyclohexanone, phenol, polycycloolefin resin, chlorinated cyclohexane, rubber additives, cyclohexanol, etc. it is also used as a catalyst solvent and petroleum extraction agent, high octane gasoline stabilizer. 3. it is used for preparation of adipic acid, maleic acid, hexahydro benzoic acid and acetaldehyde, preparation of butadiene in the laboratory. it is used as high-octane gasoline stabilizer.
production method	cyclohexanol is heated to generate cyclohexene in the presence of sulfuric acid catalyst, distilled to obtain crude products. washed with a fine saturated salt solution, then sodium sulfate solution is used to neutralize traces of acid, then washed with water, layered, dried, filtration, distillation, collecting 82-85 ℃ distillate products to obtain cyclohexene.
category	flammable liquids.
toxicity grading	toxic
acute toxicity	inhalation-rats tcl0: 600 ppm/6 hrs/26 weeks.
explosive hazardous characteristics	it can be explosive mixed with air.
flammability hazard characteristics	in case of fire, high temperature, oxidant, it is flammable, burning produces irritant smoke.
storage characteristics	treasury ventilation low-temperature drying, stored separately from oxidants and acids. not long storage to prevent polymerization.
extinguishing agent	dry powder, dry sand, carbon dioxide, foam, 1211 fire extinguishing agent.
occupational standards	twa 1015 mg/cubic meter.
chemical properties	colourless liquid
general description	a colorless liquid. insoluble in water and less dense than water. flash point 20°f. vapors heavier than air. inhalation of high concentrations may have a narcotic effect. used to make other chemicals.
air & water reactions	highly flammable. insoluble in water.
reactivity profile	cyclohexene may react vigorously with strong oxidizing agents. may react exothermically with reducing agents to release hydrogen gas. in the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. oxidizes readily in air to form unstable peroxides that may explode spontaneously [bretherick, 1979 p.151-154].
health hazard	may cause toxic effects if inhaled or absorbed through skin. inhalation or contact with material may irritate or burn skin and eyes. fire will produce irritating, corrosive and/or toxic gases. vapors may cause dizziness or suffocation. runoff from fire control or dilution water may cause pollution.
fire hazard	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.
