프로필벤젠 속성

프로필벤젠 C화학적 특성, 용도, 생산

화학적 성질

colourless or light yellow liquid

물리적 성질

Clear, colorless, mobile liquid with an odor similar to ethylbenzene or toluene. An odor threshold concentration of 3.8 ppb_v was determined by a triangular odor bag method (Nagata and Takeuchi, 1990). Cometto-Mu?iz and Cain (1994) reported an average nasal pungency threshold concentration of 1,487 ppm_v.

용도

n-Propylbenzene is used to prepare benzoic acid. It is employed as a solvent for gas chromatography. It is also used as a solvent and an intermediate in organic synthesis. Further, it is used in fuels and fuel additives.

정의

ChEBI: An alkylbenzene that is benzene having one of its aromatic hydrogens substituted by a propyl group.

일반 설명

A clear colorless liquid. Insoluble in water and less dense than water. Flash point 86°F. Mildly toxic by ingestion and inhalation. Used to make other chemicals.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as PROPYL BENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

위험도

Flammable, moderate fire risk.

건강위험

May be harmful by inhalation, ingestion, or skin absorption. May cause eye and skin irritation.

화재위험

Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flashback.

환경귀착

Biological. A Nocardia sp., growing on n-octadecane, biodegraded propylbenzene to phenylacetic acid (Davis and Raymond, 1981). Propylbenzene was cometabolized by a strain of Micrococcus cerificans to cinnamic acid (Pitter and Chudoba, 1990).
Estimated half-lives of propylbenzene (0.8 μg/L) from an experimental marine mesocosm during the spring (8–16 °C), summer (20–22 °C), and winter (3–7 °C) were 19, 1.3, and 11 d, respectively (Wakeham et al., 1983).
Photolytic. A rate constant of 3.7 x 10^-9 L/molecule?sec was reported for the reaction of propylbenzene with OH radicals in the gas phase (Darnall et al., 1976). Similarly, a room temperature rate constant of 5.7 x 10^-12 cm³/molecule?sec was reported for the vapor-phase reaction of propylbenzene with OH radicals (Atkinson, 1985). At 25 °C, a rate constant of 6.58 x 10-12 cm³/molecule?sec was reported for the same reaction (Ohta and Ohyama, 1985).
Chemical/Physical. Propylbenzene will not hydrolyze because it does not contain a hydrolyzable functional group (Kollig, 1993).
