A method for producing 2,6-diethyl-4-methylphenylacetic acid comprising a step of reacting a 2,6-diethyl-4-methylphenyl magnesium halide with ethylene oxide to obtain 2-(2,6-diethyl-4-methylphenyl) ethanol; and a step of oxidizing 2-(2,6-diethyl-4-methylphenyl) ethanol. The oxidation is conducted preferably further in the presence of a nitroxyl radical, and more preferably in the presence of a salt of a hypohalous acid and/or a salt of a halous acid.
一种生产2,6-二乙基-4-甲基苯乙酸的方法,包括以下步骤:将2,6-二乙基-4-甲基苯基镁卤化物与环氧乙烷反应,以获得2-(2,6-二乙基-4-甲基苯基)乙醇;然后将2-(2,6-二乙基-4-甲基苯基)乙醇进行氧化。最好在亚硝基自由基的存在下进行氧化,更好的是在次氯酸盐和/或卤酸盐的存在下进行氧化。
