Old phenols purification


I have 2 questions:
1) Except for phenol, which other phenols do degrade upon exposure to air ?
2) Is there any method that can be used to purify the phenols except for distillation ?

In addition I'd also like to know the air oxidation/degradation products of PhOH.

Many phenols, especially diols and aminophenols make quinones and related compounds. Here is my excellent graphic for you:
