Sodium perborate monohydrate, NaBO H2O or Na2B2(02)2(0H)4, 16.0 wt % active oxygen, is commercially prepared by dehydration of the tetrahydrate. The monohydrate has the same peroxyborate anion (7), as the higher hydrates and is the anhydrous sodium salt of this anion. Further dehydration results in decomposition of the peroxyborate. 

In 1986, Turkey produced nearly one million metric tons of mineral concentrate, whereas production of refined borate chemicals was 89,500 metric tons. Annual production capacities of chemicals at Eskiseher were pentahydrate borax, 160,000 t anhydrous borax, 60,000 t and decahydrate borax, 17,000 t. Capacities at Bandermes were decahydrate borax, 55,000 t boric acid, 33,000 t and sodium perborate, 64,000 t (103).

Perborates, or peroxoborates, are usually written as if the perborate anion were BO3. The three known sodium perborates are therefore conunonly referred to as the mono-, tri-, and tetrahydrates, NaB03 H20, where n = 1, 3, and 4. However, these actually contain the cyclic dianion (8). On the basis of this structure, these compounds are more correctly referred to as anhydrous, tetrahydrate, and hexahydrate. 

Similar migration of the other two R groups and hydrolysis of the B-0 bonds leads to the alcohol and boric acid. Retention of configuration is observed in R. Boranes can also be oxidized to borates in good yields with oxygen," with sodium perborate NaBOs," " and with trimethylamine oxide, either anhydrous" or in the form of the dibydrate." The reaction with oxygen is free radical in nature." ...

Sodium perborate is available as the so-called tetrahydrate (NaB03 4H20 or PBS4) or monohydrate (NaBOs H2O or PBSl). The monohydrate is produced by dehydration of the tetrahydrate. The perborates are true persalts, having the structure shown in Fig. 1 [7]. It can be seen from the structure that the monohydrate is actually an anhydrous salt and the tetrahydrate is a hexahydrate. The nomenclature of PBSl and PBS4 arose before the true structures of these salts were known. 

Since these products are often manually handled during, for instance, swimming pool cleaning and maintenance, they must be converted into shapes with properties that avoid nuisance dust and enhance stability. The pure chemicals, which, as produced, may be very fine (e.g., sometimes precipitated), are often mixed with other components for specific performance. For example, Oxone can be blended with many additives, including sodium-sulfate, -carbonate (especially the dense version), -bicarbonate, -perborate, -tripolyphosphate, -metasUicate, tetrasodium pyrophosphate, citric-, malic-, and tartaric-acids and surfactants and fragrances. To maintain stability, all ingredients must be anhydrous or hold hydrated water tightly.
