US3650907A Method of separating 2,6-naphthalic acid from 6-formyl-2-naphthoic acid 失效
从6-甲基-2-萘酸分离2,6-萘三酸的方法

Method of separating 2,6-naphthalic acid from 6-formyl-2-naphthoic acid
摘要：
Mixtures of 6-formyl-2-naphthoic acid and 2,6-naphthalic acid formed from the oxidation of 2,6-dimethylnaphthalene are readily separable by the steam distillation of their esters. This method has a further advantage in that it removes trace amounts of color bodies from the aldehyde ester.
摘要（中）：

通过2,6-二甲基萘的氧化形成的6-甲酰基-2-萘甲酸和2,6-萘二甲酸的混合物可以通过其酯的蒸汽蒸馏而容易地分离。 该方法的另一个优点是从醛酯中除去痕量的着色体。
