In organic chemistry, alkylammonium refers to cations of the formula [R4−nNHn] , where R = alkyl and 1≤ n ≤ 4. The cations with four alkyl substituents, i.e., [R4N] , are further classified as quaternary ammonium cations and are discussed more thoroughly in the article with that title. In contrast to quaternary ammonium cations, other members of the alkylammonium cations do not exist appreciably in the presence of strong base because they undergo deprotonation, yielding t… WebMar 2, 2024 · The aim of this work was application of ground eggshells in various amounts by weight as a biofiller for natural rubber (NR) biocomposites.
