[Extraction of 1,2- and 1,4-dihydroxybenzene from water solutions]. / Ekstragirovanie 1,2- i 1,4-dioksibenzola iz vodnykh rastvorov.

The results of extraction of 1,2- and 1,4-dihydroxybenzene from water solutions by the hydrophobic and hydrophilic organic solvents are described. The influence of an extragent nature and of a water-phase pH medium on an extraction degree is demonstrated. The repetition factor needed to extract a preset quantity of examined compounds is calculated.
