| titleOfInvention | Method for producing pentaerythritol (meth) acrylic ester |
| abstract | (57) [Summary] [Structure] When esterifying pentaerythritol and (meth) acrylic acid in the presence of a catalyst, a polymerization inhibitor and an organic solvent, a temperature of 80 to 90 ° C is used in the first step. After carrying out the reaction for 10 minutes to 3 hours while keeping the generated water in the reaction system while maintaining this temperature range from the time when the temperature reached the inside, In the following second step, the reaction temperature is set lower than that in the first step to remove the produced water from the reaction system to complete the reaction, thereby producing pentaerythritol (meth) acrylic ester. Method. According to the production method of the present invention, pentaerythritol (meth) having a triacrylic ester / pentaacrylic ester ratio capable of maintaining a liquid state at room temperature and having a high yield and a high purity is obtained. ) It is possible to obtain an acrylic ester. |
