dihydric and trihydric acids weaker than some monohydric acids ([H.sub.3][PO.sub.4] is weaker than [HCIO.sub.4]).
It was also found to contain a
dihydric alcohol as major component.

Different solvents, such as [C.sub.1]-[C.sub.12] aliphatic alcohols, and monohydric and
dihydric alcohols can be used, with methanol and ethanol being designated as the preferred extraction agents.

As earlier, the interest of scientists is focused on products obtained on the basis of
dihydric phenols, now especially on compounds with long alkyl side chains, so-called oil-soluble phenols.
