Tertiary amine oxides are made which are substantially free of nitrosamine impurities by reacting the desired tert-amine with aqueous hydrogen peroxide in the presence of carbon dioxide and at a temperature below about 45°C, especially below 40°C. Nitrosamines are suspect carcinogens and mutagens.
将所需的叔胺与
过氧化氢水溶液在有
二氧化碳存在的情况下,在低于约 45℃,特别是低于 40℃的温度下进行反应,可制成基本上不含亚
硝胺杂质的叔胺氧化物。亚
硝胺是可疑的致癌物质和诱变剂。
