1. A method for preparing a high refractive (meth)acrylate derivative, the method comprising:
1) preparing a compound represented by the following Chemical Formula b by putting a fluorene derivative represented by the following Chemical Formula a, paraformaldehyde (PFA), and an acid into a first reactor, followed by a reaction; 2) preparing a KOH/(meth)acrylic acid aqueous solution by putting a KOH aqueous solution and a (meth)acrylic acid represented by the following Chemical Formula c into a second reactor, followed by putting Tetra-n-butylammonium bromide (TBAB) thereinto; and 3) preparing a (meth)acrylate derivative represented by the following Chemical Formula 1 by an esterification reaction of the compound represented by the following Chemical Formula b, the reaction product of the step 1), with the KOH/(meth)acrylic acid aqueous solution of the step 2): wherein X is O or S, and R is hydrogen or methyl. |
