Apparatus for producing hydroxyalkyl(meth)acrylate and process for producing the same |
| abstract |
The present invention provides an apparatus for producing hydroxyalkyl(meth)acrylate and method for producing hydroxyalkyl(meth)acrylate, which can maintain high sealing performance even if the maintenance frequency of the blowdown valve is reduced. The apparatus for producing hydroxyalkyl(meth)acrylate of the present invention has a reaction vessel for synthesizing hydroxyalkyl(meth)acrylate, which has a blowdown valve placed in the reaction vessel, and the blowdown valve is opened when discharging contents of the reaction vessel and is a ball valve. The method of producing hydroxyalkyl(meth)acrylate of the present invention involves producing hydroxyalkyl(meth)acrylate using the aforementioned apparatus for producing hydroxyalkyl(meth)acrylate. |
