Abstract

The Reaction of Aliphatic Isocyanates with Sul-furic Acid.-Ethyl isocyanate, a typical aliphatic isocyanate, was allowed to react with 20% oleum, 5% oleum and concentrated sulfuric acid. In each case carbon dioxide was readily evolved in the cold. The formation of a transitory white solid, which dissolved with gas evolution and which
