Process for isolating 1,4,7,10,13,16- hexaoxacyclooctadecane (A) in high yield from a mixture also containing other macrocyclic polyethers, by reacting A with nitromethane in the presence of a solvent for these macrocyclic polyethers, to precipitate a complex of A and nitromethane, separating the complex from the reaction mixture and dissociating the separated complex into A and nitromethane.
从含有其他大环聚醚的混合物中高产分离出 1,4,7,10,13,16-六氧杂环十八烷(A)的工艺,方法是在这些大环聚醚的溶剂存在下,使 A 与硝基甲烷反应,沉淀出 A 与硝基甲烷的络合物,从反应混合物中分离出络合物,并将分离出的络合物解离成 A 和硝基甲烷。
