production method 1. Preparation Method: indan-1, 2-diol monoformate (3): add 88% formic acid to the reaction bottle equipped with stirrer, thermometer and dropping funnel (), 30% mL(1.37mol) of hydrogen peroxide, indene (2)116.2g[117.3mL,1.0mol(98%)] was slowly added dropwise under stirring at 35-40 ° C. For about 2 hours. Finally 100ml of formic acid was added to rinse the dropping funnel. The reaction was stirred at room temperature for 7H to complete the reaction. Formic acid (2.66-4.0kPa) was distilled off under reduced pressure and the residue was cooled to room temperature to give a light brown solid (3). 2-indanone (1): 7% of sulfuric acid 2L and compound (3) were added to a distillation flask, and steam distillation was performed. The outflow rate is about 1L/h, and the volume of the reaction bottle is kept at about 2L by adding water at any time. A total of 5-6L of distillate is collected. The dark brown liquid in the bottle became semi-solid after cooling. The distillate was cooled and filtered to obtain a white solid. After drying under vacuum for more than 12h, 90 ~ 107g of compound (1) was obtained, mp57 ~ 58 ℃, yield 69% ~ 81%. [1]
