Process for preparing solid acetyl phosphate salt

摘要

A salt of monoacetyl phosphate which is useful in the field of enzymatic reactions can be obtained as a precipitate by using a specified amount of lithium ion as a precipitating agent in the process for the acetylation of phosphoric acid or its salt with acetic anhydride. The resulting precipitate can be separated from the reaction mixture by filtration without necessity of operation at a low temperature or the replacement of solvents.
