The main components are benzene, toluene, xylene, and trimethylbenzene (the above are referred to as "light aromatics") as well as naphthalene, methylnaphthalene, indene, and gumarone, with small amounts of styrene and phenolic substances. Among them, naphthalene, methyl naphthalene, indene, gumarone, etc. have high added value, so it is necessary to extract them. However, due to the complex composition of heavy benzene, there are few ways to process it, mainly and mostly at a relatively low processing level, with low resource utilization efficiency and little value-added products, so further research is needed. In terms of application, heavy benzene can be used to formulate paints, inks, adhesives, etc. It can also replace toluene and xylene to make banana water and tianna water, etc.

Light yellow needle-like crystals. Melting point 113.3-114.5 ℃, with a strong musk gas, with a sweet musk-like animal aroma, lasting fragrance.

An organic compound with the molecular formula C8H10, a colorless and transparent liquid, is the product of the substitution of two hydrogens on the benzene ring by methyl, and there are three isomers: o-, m- and p-. In industry, xylene refers to the mixture of the above isomers.
