Theoretical and practical investigations of copper ion selective electrode with polymeric membrane based on N,N’-(2,2-dimethylpropane-1,3-diyl)-bis(dihydroxyacetophenone) was written by Ghanei-Motlagh, Masoud;Taher, Mohammad Ali;Saheb, Vahid;Fayazi, Maryam;Sheikhshoaie, Iran. And the article was included in Electrochimica Acta in 2011.Name: Dimethyl decanedioate This article mentions the following:
A novel ion-selective poly(vinyl chloride) (PVC) membrane sensor for Cu2+ ions based on N,N’-(2,2-dimethylpropane-1,3-diyl)-bis(dihydroxyacetophenone) (NDHA) as a new ionophore was prepared and studied. The best performance was observed for the membrane composition, including 30:65:1:4 (wt%) = PVC:DBP:KTpClPB:NDHA. The electrode showed a good Nernstian slope of 30.0 鍗?0.5 mV/decade in a wide linear range activity of 3.0 鑴?10-7 to 1.0 鑴?10-2 mol dm-3 Cu(NO3)2 with limit of detection 2.5 鑴?10-7. Sensor exhibited a fast response time (t 95% < 10 s) and could be used for 閳? mo in the pH range of 3.0-7.4. The proposed potentiometric sensor was found to work satisfactorily in partially nonaqueous media up to 30 (vol%) content of MeOH, EtOH and acetone. Applications of this electrode for the determination of Cu in real samples, and as an indicator electrode for potentiometric titration of Cu2+ ion using EDTA, are reported. To predict the extraction ability of NDHA for different metallic ions, [M(NDHA)] and [M(H2O)6] (M = Cu2+, Co2+, Hg2+, Pb2+, Ag+, Mg2+, Ca2+, Mn2+, Zn2+, Cd2+, K+ and Al3+) were studied using ab initio theor. calculations The metal binding capability was evaluated using the binding energy. Results of the authors’ study could be useful for prediction of the extraction power of this Schiff base and could play a guiding role in planning experiments In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Name: Dimethyl decanedioate).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Dimethyl decanedioate
