Abstract:

Reaction of reamidation of rubeanic acid with aminopropyl polysiloxane was systematically studied. It was found that the given type of transformations make it possible to obtain a derivative of aminopropyl polysiloxane with surface dithiooxamide groups in a concentration of up to 0.78 mmol g(-1) at a total degree of substitution of up to 0.25. The composition and structure of the derivatives obtained were characterized by elemental analysis, IR spectroscopy, thermogravimetry, and method of low-temperature adsorption of nitrogen. The sorption of Ni(II), Pd(II), and Pt(II) in a 0.2 M solution of hydrochloric acid was evaluated for the products obtained.
