In 1988 Promox has developed the know-how for the synthesis of peracetic acid solutions.
In 2008 Promox start up the new plant for the synthesis of ketone peroxide always in leggiuno (Varese).
AP has several different forms, di-, tri- and tetra peroxides. Power and stability increases with size of molecule, meaning that tetrameric peroxide is most powerful and stable, while dimeric is the opposite. The ratios of these isomers depend on reaction conditions during synthesis. Many have been killed or severely injured while trying to synthesis AP. The most common error is that of temperature. When making the tricycloacetone peroxide, temperature must be less than 10°C at all times, otherwise dicycloacetone peroxide may be formed, which is extremely unstable and so sensitive that it has practically no uses at all - dicycloacetone peroxide has been known to explode spontaneously.
* It is always better to add a bit excess Hydrogen peroxide. (from AP synthesis experiments)
* Sulphuric acid is used as a catalyst, however, other acids can be used. Citric acid and hydrochloric acid can be used. Temperature rise is more significant though when sulphuric acid is used.
* 3% hydrogen peroxide can be used too, if 30% hydrogen peroxide cannot be obtained. However, yields might be lower. Measures must be adjusted. Same goes with the acid.
