Preparation of peracetic acid

Peracetic acid is almost always used in acetic acid solution, for in pure or concentrated form peroxyacetic acid is highly explosive. Acetic acid solutions of peroxyacetic acid are obtained by mixing acetic acid or acetic anhydride with 25-90% hydrogen peroxide and then adding a little (1%) concentrated sulfuric acid as catalyst (armoured cupboard, danger of explosion). When 30% hydrogen peroxide is used the concentration of the peracid reagent obtained is less than 10%. If a stronger solution of the reagent is required, 70-90% hydrogen peroxide must be used. In the preparation of peracetic acid from acetic anhydride and hydrogen peroxide, the dangerously explosive diacetyl peroxide may become the major product if the reaction is not carried out properly.
