So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Gajda, Bernadeta; Plackowski, Radoslaw; Skrzypczak, Andrzej; Bogacki, Mariusz B. researched the compound: 1-Bromoundecane( cas:693-67-4 ).Formula: C11H23Br.They published the article 《Facilitated transport of copper(II) across polymer inclusion membrane with triazole derivatives as carrier》 about this compound( cas:693-67-4 ) in Membranes (Basel, Switzerland). Keywords: polymer inclusion membrane copper ion transport triazole derivative carrier; 1-alkyl-1,2,4-triazole; copper transport; polymer inclusion membrane; selective transport. We’ll tell you more about this compound (cas:693-67-4).
This study investigates copper(II) ion transport through a polymer inclusion membrane (PIM) containing 1-alkyl-1,2,4-triazole (n = 8, 9, 10, 11, 12, 14), o-nitrophenyl octyl ether as the plasticizer and cellulose triacetate as the polymer matrix. The feeding phase was a solution of 0.1 mol/dm3CuCl2 and an equimolar (0.1 mol/dm3) mixture of copper, nickel, and cobalt chlorides with varying concentrations of chloride anions (from 0.5 to 5.0 mol/dm3) established with NaCl. The receiving phase was demineralized water. The flow rate of the source and receiving phases through the membrane module was within the range from 0.5 cm3/min to 4.5 cm3/min. The tests were carried out at temperatures of 20, 30, 40 and 50°C. Transport of NaCl through the membrane was excluded for the duration of the test. It was noted that the flow rate through the membrane changes depending on the length of the carbon chain in the alkyl substituent from 16.1μmol/(m2s) to 1.59μmol/(m2s) in the following order: C8 > C9 > C10 > C11 > C12 > C14. The activation energy was 71.3 ± 3.0 kJ/mol, indicating ion transport through the PIM controlled with a chem. reaction. Results for transport in case of the concurrent separation of copper(II), nickel(II), and cobalt(II) indicate a possibility to sep. them in a selective manner.
As far as I know, this compound(693-67-4)Formula: C11H23Br can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
