According to the present invention, a tank for storing an easily polymerizable compound, the tank fitted with a liquid inlet pipe 3, a liquid draw-off pipe 4 and a liquid recirculating pipe 5, is characterized in that, assuming terminal ends of the individual pipes 3-5 are located at the same height, the apex angle formed by a line joining the central points of the end openings of the pipe 3 and the pipe 4 at the central point of a horizontal cross section of the tank, or the apex angle formed by a line joining the central points of the pipe 5 and the pipe 4 at the central point of the horizontal cross section of the tank, is equal to or larger than 90°. A method of storing an easily polymerizable compound of the invention utilizes the aforementioned tank for storing the polymerizable compound.
A tank for storing an easily polymerizable compound, the tank fitted with a liquid inlet pipe, a liquid draw-off pipe and a liquid recirculating pipe, wherein at least one of the liquid inlet pipe and the liquid recirculating pipe is arranged in such a position with respect to the liquid draw-off pipe that, when viewed from above, the apex angle of a triangle formed by a line joining the central points of both end openings of the liquid inlet pipe and the liquid draw-off pipe and the point of intersection of horizontal lines extended individually from the central points of the end openings of the liquid inlet pipe and the liquid draw-off pipe to the central point of a horizontal cross section of the tank, is equal to or larger than 90°.
