<p>A method for preparing 2, 5-dihydroxyterephthalic acid is provided. The raw material of 1, 4-dihalo-2, 5-dialkoxybenzene is converted to 2, 5-dialkoxyterephthalic acid via Grignard carboxylation, and 2, 5-dialkoxyterephthalic acid undergoes dealkylation to give 2, 5-dihydroxyterephthalic acid. The method has the advantages of simple operation, short time, easy control, high yield and high product purity.</p> |
