The present invention provides a process for producing aromatic compounds or polymers thereof from a plant material in a short period of time and by a simple procedure. Concretely, the process treats the plant material with supercritical water or subcritical water to liberate aromatic compounds, which are contained in the plant material, and/or aromatic compounds, which have been generated upon decomposition of components of the plant material, to the outside of the plant material, and isolates the liberated aromatic compounds to produce aromatic compounds or polymers thereof.

A invenção atual fornece um processo produzindo compostos ou polímeros aromatic disso de um material de planta em um período do tempo curto e por um procedimento simples. Concreta, o processo trata o material de planta com água supercritical ou água subcritical para liberate os compostos aromatic, que são contidos no material de planta, e/ou os compostos aromatic, que foram gerados em cima do decomposition dos componentes do material de planta, à parte externa do material de planta, e dos isolates os compostos aromatic liberated para produzir compostos ou polímeros aromatic disso.
