Simple preparation process of 9-fluorenemethanol
The preparation of 9-fluorenemethanol: 1) preparing industrial fluorene, sodium ethoxide, ethyl formate and tetrahydrofuran in a ratio of 50g:15g:50ml:200ml, adding tetrahydrofuran of sodium ethoxide into a four-mouth bottle, controlling the temperature at 0-10DEG C, adding a tetrahydrofuran solution of industrial fluorene dropwisely, adding ethyl formate, and raising the temperature to 30-40DEG C, thus obtaining 9- fluorenecarboxaldehyde; and 2) adding methanol and NaBH4 under ice bath, conducting reduction to obtain a 9-fluorenemethanol crude product, carrying out recrystallization so as to obtain white needlelike 9-fluorenemethanol. The crude product purity is enhanced, the reaction conditions are mild, and the cost is lowered, so that the method is easy for industrialization.
