What is Modified Method for Picramic Acid about?

The document describes a modified method for preparing picramic acid that improves upon existing methods by avoiding the formation of byproducts. It involves dissolving picric acid in alcohol, neutralizing it with ammonium hydroxide and cooling the solution before adding hydrogen sulfide to precipitate picramic acid. This new method yields 76.5% of the theoretical amount of picramic acid, compared to lower yields and more byproducts from previous methods.
