摘要
Isobutylene, hydrogen cyanide and sulfuric acid are reacted to produce tertiary butyl formamide, which is hydrolyzed by sodium hydroxide to produce tertiary butyl amine. The tertiary butyl amine is removed by vaporization and the residue is treated with sulphuric acid and methanol and is distilled to recover formate values as methyl formate or sodium formate. There is additionally recovered crystalline sodium sulfate and a water immiscible yellow organic phase.
