Method of synthesis of adamantane-2-one |
| abstract |
FIELD: organic chemistry and technology. SUBSTANCE: adamantane-2-one is synthesized by oxidation of adamantane with concentrated sulfuric acid or with addition of sulfuric anhydride at catalytic amount. Oxidation is carried out in adamantane reaction mass and an adamantanol as an intermediate. After reaction termination reaction mass is poured on ice and neutralized with alkaline agent. Adamantanone is distilled off with steam and filtered off. Additional amount of adamantanone is extracted from an aqueous filtrate with an organic solvent. EFFECT: increased yield, improved quality of the end product, improved ecology, prolonged equipment exploitation. 8 cl |
