Electronic spectroscopy of solutions of heterocyclic compounds in sulfuric acid

The behavior of furan derivatives in strongly acidic media was investigated by means of electronic spectroscopy. It is shown that at concentrations of 10^–5 to 10^–6 mole/liter a number of the investigated compounds are stable in sulfuric acid of any concentration because of a decrease in the probability of polymerization processes.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1594–1596, December, 1972.
