BEIGE TO LIGHT YELLOW-BROWN CRYSTALLINE POWDER

2-Methylanthracene (cas# 613-12-7) is a compound useful in organic synthesis.

Detected in 8 diesel fuels at concentrations ranging from 0.18 to 160 mg/L with a mean value of 46.16 mg/L (Westerholm and Li, 1994). Schauer et al. (1999) reported 2- methylanthracene in diesel fuel at a concentration of 6 μg/g and in a diesel-powered medium-duty truck exhaust at an emission rate of 10.4 μg/km.
California Phase II reformulated gasoline contained naphthalene at a concentration of 5.54 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were approximately 1.14 and 94.1 μg/km, respectively (Schauer et al., 2002).

Chemical/Physical. 2-Methylanthracene will not hydrolyze because it has no hydrolyzable functional group.

Chromatograph it on silica gel with cyclohexane as eluent and then recrystallise it from EtOH [Werst J Am Chem Soc 109 32 1987]. [Beilstein 5 IV 2311.]
