摘要:
A compound having a binaphthalene skeleton represented by the following formula (1):
(wherein R 1 and R 2 each independently represent a hydrogen atom, a halogen atom or a hydrocarbon group which may contain an aromatic group having 1 to 12 carbon atoms; Ar 1 and Ar 2 represent an aromatic group which may have a substituent having 6 to 10 carbon atoms; L 1 and L 2 represent an alkylene group having 1 to 12 carbon atoms; j and k each independently represent an integer of 0 to 5; m1, m2, n1 and n2 each independently represent an integer of 0 to 4, and m1 + m2 ≥ 1, where m1 + n1 is an integer of 4 or less, and m2 + n2 is an integer of 2 or less) , wherein the content of palladium element in the compound having a binaphthalene skeleton satisfies the following formula (2): 0 ≤ Pd ≤ 50 ppm This compound having a binaphthalene skeleton has a small content of a specific metal such as palladium or a specific compound in a raw material alcohol, and is characterized by having excellent hue and various characteristics (optical properties, heat resistance, moldability, etc.) of the raw material and a resin using the raw material.
