Abstract
Спосіб отримання пікринової кислоти включає нітрацію нітропохідних фенолу. Здійснюють нітрацію о-нітрофенолу і/або п-нітрофенолу до дінітрофенолу так, щоб продукт, що утворюється, був розчинним у реакційному середовищі, і продовжують нітрацію дінітрофенолу до отримання пікринової кислоти, що випадає в осад.
