Abstract
A fibrous anion exchanger with ternary amino groups of dimethylaminopropylamine was obtained on the base of a polyacrylonitrile fiber by the previously proposed method of catalytic amination of nitrile groups. A fibrous anion exchanger with strong base functional groups was synthesized on the base of this material by the reaction of alkylation of its groups with epichlorohydrin solutions. Their exchange capacities, acid-base properties, sorption of acetic acid vapors from air with different relative humidity were determined. The boundary and optimal conditions of application of the obtained ion exchangers in the processes of air purification from acetic acid and the dynamic characteristics of filtration layers were established.
