The invention discloses a nitration method of aromatic compounds and particularly relates to a method for nitrating aromatic compounds in a supergravity reactor. The method comprises steps as follows: the aromatic compounds and mixed acid are input into the supergravity reactor, mixed and subjected to a nitration reaction to produce a nitration product. The nitration method of the aromatic compounds has the characteristics of being high in production efficiency, low in energy consumption and the like and is environment-friendly, safe, efficient and low-cost.
