In 2022,Nagarale, Rajaram. K.; Bavdane, Priyanka P.; Sreenath, Sooraj; Pawar, Chetan M.; Dave, Vidhiben; Satpati, A. K. published an article in Journal of Polymer Research. The title of the article was 《Polyaniline derivatized anion exchange membrane for acid recovery》.Related Products of 1445-73-4 The author mentioned the following in the article:
Herein we are demonstrating the utility of an aniline derivatized anion exchange membrane for acid recovery by diffusion dialysis. The membrane was synthesized by oxidative polymerization of N-Methyl-4-piperidone derivative and confirmed by detailed spectroscopic characterisations. Free-standing membranes M1 and M2 was obtained by addition of different amount of PVA. For the comparison purpose, PVA blend with neat polyaniline was synthesized. Excellent physicochem. properties coupled with outstanding chem. stability in bentonite mine effluent with total acid concentration of ∼ 8 M, drawn interest to use in acid recovery by diffusion dialysis. In a simulated solution containing 6% iron and 3.5 M HCl, calculated proton dialysis coefficient (UH+) was 31 x 10-3 m h-1 and iron dialysis coefficient (UFe2+) was 3 x 10-4 m h-1 for the best membrane M2. It corresponded to separation factor (S) of 103 units, which was comparable with literature known best membranes like Neosepta. For effluent solution obtained from a local bentonite mine, membrane M2 showed UH+ value of 37 x 10-3 m h-1 and UFe2+ value of 6 x 10-4 m h-1 suggesting its best utility in acid recovery. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-piperidone(cas: 1445-73-4Related Products of 1445-73-4)
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Related Products of 1445-73-4
