Zusammenfassung:	PROBLEM TO BE SOLVED: To provide: a 2,6-tetralin dimethyl alcohol that is a novel tetralin derivative for which a utilization as a resin raw-material, liquid crystal composition, polymer modifier, pharmaceutical intermediate or the like may be considered; and a production process therefor.SOLUTION: 2,6-tetralin dimethyl alcohol (1) is produced by contact-reduction-reacting 2,6-tetralin dicarboxylic carboxylic acid dialkyl ester, in the presence of a solvent and a copper-chromium-based hydrogenation catalyst, with hydrogen.SELECTED DRAWING: None 【課題】樹脂原料、液晶組成物、高分子改質剤、医薬中間体などとしての利用が考えられる新規テトラリン誘導体である２，６-テトラリンジメチルアルコール、及びその製造方法を提供する。【解決手段】２，６−テトラリンジカルボン酸ジアルキルエステルを、溶媒と銅クロム系水素化触媒の存在下、水素で接触還元反応させることにより、２，６−テトラリンジメチルアルコール（１）を製造する。【選択図】なし
