Solvay Interox

Calcium peroxide is made by EMC, L Air Liquide, Nippon Peroxide (Japan), Shimakyo Chemical (Japan), Solvay Deutschland, Solvay Interox (United Kingdom), and Tomita Seiyaku (Japan). Trade names used for calcium peroxide are Calper, IXPER 60 C, IXPER 75 C, PermeOx, and Trap2ene. The world market for calcium peroxide ia 1992 was about 2000 t. The U.S. prices ia 1994 were, for the food-grade (75% Ca02), 3.97/kg and for the technical grade (60%), 2.97—3.30/kg. 

The world market in 1993 was about 450,000 t. Sodium peroxoborate is made commercially by Atochem, Ausimont, Caffaro, Degussa, Eka Nobel, Foret, L Air Liquide, Solvay Interox (Belgium, Italy, Germany, United Kingdom, United States), and Treibacher Chemische Werke. The U.S. price in 1994 was in the range 1.32—1.43/kg, the German price was DM 1.35—1.60/kg ( 0.78—0.92/kg). 

The efforts of other Solvay Interox personnel including, S.E. Blackett, S.C. Oakes, D. Pyke and S. L. Wilson, in developing this technology are gratefully acknowledged.

Direct synthesis of hydrogen peroxide from its elements is thermodynamically feasible and it is a known reaction from the beginning of the last century [11], However, intense research activity in many companies on the direct synthesis of H202 only began in 1980. Some 100 patents were issued in the 1980s and 1990s from companies such as Air Products, BASF, Dow Chemicals, Du Pont, ENI, Eka Nobel, FMC, Solvay Interox, Mitsubishi Gas Chemical and Shell. Table 8.2 summarizes some selected comparative results.

Percarboxylic acids have been used widely in Baeyer-Villiger oxidation. Peracetic acid is one of the most commonly used peracids distilled peracetic acid is employed commercially by Solvay Interox for the production of e-caprolactone.246 The use of distilled peracetic acid is essential, as it contains no strong protic acids which can catalyse polymerization of the resulting lactone and cause other side reactions. Figure 3.53 illustrates the use of pre-formed peracetic acid for the Baeyer-Villiger oxidation of ketones.247,248...
