ABSTRACT:
The storage tank of the invention for an easily polymerizable compound is a storage tank having an acceptance piping and a delivery piping and is characterized by having a circulation line which directly connects the acceptance piping to the delivery piping or having circulation lines which respectively connect the acceptance piping to the storage tank and the storage tank to the delivery piping; the method of storing of the invention is characterized by storing an easily polymerizable compound in the storage tank while circulating the compound in the storage tank through the circulation line(s); the method of pipe jointing and apparatus therefor of the invention are a method of jointing pipes fitted to a handling apparatus in a production apparatus, storage apparatus, or the like for the purpose of transporting a corrosive liquid, the method being characterized in that the pipes are jointed with flanges, bolts, and nuts made of a material having resistance to corrosion by the corrosive liquid; the process for (meth)acrylic acid compound production of the invention is a process for producing and/or purifying a (meth)acrylic acid compound, and is characterized in that the temperature of a purified (meth)acrylic acid compound obtained which is being supplied to a storage tank is regulated so as to be not higher than the temperature of the purified (meth)acrylic acid compound residing in the storage tank; and the process of the invention for producing an easily polymerizable compound which is a (meth)acrylic acid compound is characterized in that the temperature of a (meth)acrylic acid compound-containing liquid which has been discharged as an off-specification product and is being supplied to a storage tank is regulated so as to be not higher than the temperature of the off-specification liquid stored in the storage tank.
