Abstract
A method of storing (meth)acrylate in a tank of a less expensive and highly versatile material without losing stability of the stored (meth)acrylate. To be specific, a method of storing (meth)acrylate in a tank, including supplying an appropriate gas for storing (meth)acrylate into the tank, in which: the tank is made of a carbon steel material; the gas has a water concentration of 100 ppm or less; and the (meth)acrylate has a (meth)acrylic acid concentration of 30 ppm or less.
Claims18
A method of storing (meth)acrylate in a tank, comprising the steps of:
- supplying (meth)acrylate into the tank, and supplying a gas, which suppresses a polymerization reaction of (meth)acrylate in a gas phase portion and a liquid phase portion in the tank and prevents (meth)acrylate from composing an explosive composition, into the tank, wherein:
- the tank is made of a carbon steel material;
- the gas has a water concentration of 100 vol ppm or less;
- and
- the (meth)acrylate has a (meth)acrylic acid concentration of 30 mass ppm or less.
