More Information
Summary:The present specification provides a method for preparing a styrene monomer, the method comprising, as a step of preparing a styrene monomer of chemical formula 2 by reacting a compound represented bychemical formula 1 in the presence of phosphoric acid, a step of using 100 mol% or more of the phosphoric acid on the basis of 100 mol% of the compound represented by chemical formula 1. 本说明书提供了用于制备苯乙烯单体的方法，其包括通过使由化学式1表示的化合物在磷酸的存在下进行反应来制备化学式2的苯乙烯单体，其中基于100mol％的由化学式1表示的化合物，以100mol％或更大使用磷酸。
