A process for the oxidation of nonaromatic tertiary amines to the respective amine oxides. An aqueous solvent system containing the tertiary amine is formed with an initial pH about equal to or greater than the pKa of the tertiary amine. In the absence of an oxidation catalyst, this aqueous system is contacted with gaseous molecular oxygen at an oxygen partial pressure of at least about 50 psi and a temperature of at least about 80°C. The resulting oxidation converts the tertiary amine to the respective amine oxide in fairly high yields without significant formation of other reaction products.
一种将非芳香族叔胺氧化成相应胺氧化物的工艺。形成含有叔胺的水溶剂体系,其初始 pH 值约等于或大于叔胺的 pKa。在没有氧化催化剂的情况下,在氧分压至少约 50 磅/平方英寸、温度至少约 80°C 的条件下,将该水溶液体系与气态分子氧接触。由此产生的氧化作用会以相当高的产率将叔胺转化为相应的氧化胺,而不会形成大量的其他反应产物。
