| titleOfInvention | Method for crystallizing chroman-1 from an impure mixture |
| abstract | (57) Abstract: (Corrected) PROBLEM TO BE SOLVED: To provide a method for crystallizing chroman-1 from an impure mixture containing chroman-1. SOLUTION: To isolate and crystallize chroman-1 from an impure mixture, the crude mixture is heated, and the heated mixture and acetone are mixed to obtain a solid-free solution, from which solution A method of crystallizing chroman-1 is used. By repeating this method, High-purity chroman-1 is obtained in high yield. |
