1-METHYLPHENANTHRENE Chemical Properties,Usage,Production

Uses

1-Methylphenanthrene is a polycyclic aromatic hydrocarbon that has been found in particulate matter from small-scale biomass combustion from old and modern technologies and that has caused acute systemic and lung inflammation in mice after intratracheal aspiration.

Definition

ChEBI: A member of the class of phenanthrenes that is phenanthrene substituted by a methyl group at position 1.

General Description

White crystalline powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 1-METHYLPHENANTHRENE, 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. 1-METHYLPHENANTHRENE is sensitive to excessive heat and light.

Fire Hazard

Flash point data for 1-METHYLPHENANTHRENE are not available. 1-METHYLPHENANTHRENE is probably combustible.

Source

Detected in 8 diesel fuels at concentrations ranging from 0.10 to 210 mg/L with a mean value of 44.33 mg/L (Westerholm and Li, 1994). Identified in a South Louisiana crude oil at a concentration of 111 ppm (Pancirov and Brown, 1975). Schauer et al. (1999) reported 1- methylphenanthrene in diesel fuel at a concentration of 28 μg/g and in a diesel-powered mediumduty truck exhaust at an emission rate of 17.0 μg/km.
California Phase II reformulated gasoline contained 1-methylphenathrene at a concentration of 3.91 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were approximately 1.63 and 122 μg/km, respectively (Schauer et al., 2002).
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The respective gas-phase and particle-phase emission rates of 1-methylphenanthrene were 2.22 and 0.579 mg/kg of pine burned and 1.04 and 0.050 mg/kg of oak burned. The gas-phase emission rate was 0.720 mg/kg of eucalyptus burned.
