The complexing abilities of new derivatives of calixarene for cations of some s- and d-elements were established. It was found that bis(p-tert-butylcalix[4]arene)-mono(N'-acetyl)hydrazide was obtained in almost quantitative yield by refluxing of mono(hydrazinocarbonylmethoxy)-p-tert-butylcalix[4]arene in alcohol solution. This compound shows a high affinity for some transition metal cations, especially for triple-charged cations iron and aluminum.Obtaining results are apply to making of new types of sorbents, extracting and hemosensing materials based on calixarene derivatives Product Description popup.authors Алєксєєва Олена Олександрівна Басок Степан Степанович Кузьмін Віктор Євгенович Лукьяненко Олександр Петрович Мазепа Олександр Володимирович Ракіпов Ільдар Марсович popup.nrat_date 2020-04-02 Close
