Moreover, competitive experiments between 1°/2°, 2°/3°, and 1°/3° alkyl bromides showed that the reactivity order of alkyl halides is 3° > 2° > 1°, which is consistent with the order of stability of free alky …
WebAnion exchange resins consist of a polymeric matrix to which different functional groups are attached. Most weakly basic anion exchangers contain tertiary amino groups; in a few cases primary and secondary groups are also encountered. In many cases weakly basic anion exchangers are not monofunctional but possess a variety of amino groups. WebThe AEP includes primary, secondary, and tertiary amino groups in the molecule. Therefore, it was expected to show all the CO 2 absorption characteristics of primary, secondary, and tertiary amines. The single amine CO 2 absorption mechanisms are presented in the following sections, 1 and 2, to clarify the AEP characteristics. 1. Primary and ...
