1-펜텐 C화학적 특성, 용도, 생산
화학적 성질
1-Pentene, C5H10, is a flammable liquid with specific gravity 0.641. It occurs in coal tar and in petroleum cracking mixtures, and polymerizes on extended periods of storage (15, 320).물리적 성질
Clear, colorless, volatile, very flammable liquid with a disagreeable odor. An odor threshold concentration of 10 ppbv was determined by a triangular odor bag method (Nagata and Takeuchi, 1990).용도
1-Pentene is used in the preparation of d-xylitol, l-arabinitol and hydrazones of substituted salicylaldehydes. It is also used as a blending agent for of high-octane gasoline. It reacts with p-toluenesulfinate to yield 1-(2-iodo-pentane-1-sulfonyl)-4-methyl-benzene. It is also involved in Gas Chromatography and Liquid Chromatography analysis.생산 방법
1-Pentene is prepared from allyl bromide and ethyl magnesium bromide in ether or in dipropyl ether.일반 설명
Colorless liquid with an odor of gasoline. Flash point -20°F(Aldrich). Insoluble in water and less dense than water. Hence floats on water. Flammable vapor is produced. Boiling point 86°F.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
1-Pentene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. May undergo exothermic polymerization reactions in the presence of various catalysts (such as acids) or initiators.건강위험
Acts as a simple asphyxiant or weak anesthetic in high vapor concentrations. Similar to effects caused by gasoline vapors.화재위험
Behavior in Fire: Containers may explode in fire.화학 반응
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.잠재적 노출
Workers in petroleum refineries and petrochemical plants.환경귀착
Biological. Biooxidation of 1-pentene may occur yielding 4-penten-1-ol, which may oxidize to give 4-pentenoic acid (Dugan, 1972). Washed cell suspensions of bacteria belonging to the genera Mycobacterium, Nocardia, Xanthobacter, and Pseudomonas and growing on selected alkenes metabolized 1-pentene to 1,2-epoxypentane. Mycobacterium sp., growing on ethene, hydrolyzed 1,2-epoxypropane to 1,2-propanediol (Van Ginkel et al., 1987).Photolytic. The following rate constants were reported for the reaction of 1-pentene and OH radicals in the atmosphere: 1.8 x 10-13 cm3/molecule?sec at 300 K (Hendry and Kenley, 1979); 3.14 x 10-11 cm3/molecule?sec (Atkinson, 1990). Atkinson (1990) also reported a photooxidation rate constant of 1.10 x 10-17 cm3/molecule?sec for the reaction of 1-pentene and ozone.
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.

UN1108 1-Pentene, Hazard Class: 3; Labels: 3-Flammable liquid비 호환성
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Excessive heat may cause polymerization. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, heat. Incompatible with strong reducing agents such as hydrides; oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.1-펜텐 준비 용품 및 원자재
