The invention relates to a method used for preparing tetrabutylammonium fluoride trihydrate. According to the method, a tetrabutylammonium salt and potassium fluoride are dissolved in water; low temperature crystallization is carried out; pumping filtration is carried out so as to obtain tetrabutylammonium fluoride clathrate hydrate; and tetrabutylammonium fluoride trihydrate is obtained via vacuum drying. Reaction conditions of the method are mild; reaction processes are carried out in water; no organic solvent is used; the method is green and friendly to the environment; tetrabutylammonium fluoride trihydrate is obtained via crystallization separation of the tetrabutylammonium fluoride clathrate hydrate; steps are short; operation is simple and convenient; hydrofluoric acid is not used; no ion exchange column is used; no special requirement on equipment is proposed; cost is low; yield is high; and the method is suitable for industrialized production.
