1. A method of preparing a 2-alkylanthracene, comprising:
carrying out an alkylation reaction of anthracene with an alkylation reagent under an alkylation condition and in the presence of an alkylation reaction solvent and a catalyst;
obtaining a reaction product comprising anthracene and a plurality of alkylanthracenes,
wherein the plurality of alkylanthracenes comprise 2-alkylanthracene; and
separating 2-alkylanthracene from the reaction product,
wherein the separation comprises separating anthracene by melting crystallization and separating 2-alkylanthrancene by distillation, and
the alkyl in the 2-alkylanthrance is one or more selected from C4-C7 alkyls.
