PROBLEM TO BE SOLVED: To provide a novel high-purity, high-yield production method of bis (2-hydroxyethyl) 5-hydroxyisophthalate. SOLUTION: The present invention relates to a compound represented by the formula (1): (Wherein, R represents a hydrogen atom or an alkyl group.) A 5-hydroxyisophthalic acid compound represented by the following formula: When obtaining hydroxyisophthalate, a metal and a metal compound from Groups 1 to 8 of the periodic table as a catalyst, Ethylene glycol is added to 5-hydroxyisophthalic acid compound in an amount of 5 to 2 in the presence of a mineral acid, an organic acid and a solid acid. A method for producing bis (2-hydroxyethyl) 5-hydroxyisophthalate, which is used in a molar amount of 00 times. |
