The present invention provides a process for producingnaromatic compounds or polymers thereof from a plant materialnin a short period of time and by a simple procedure.nConcretely, the process treats the plant material withnsupercritical water or subcritical water to liberatenaromatic compounds, which are contained in the plantnmaterial, and/or aromatic compounds, which have beenngenerated upon decomposition of components of the plantnmaterial, to the outside of the plant material, and isolatesnthe liberated aromatic compounds to produce aromaticncompounds or polymers thereof. |
