Case Study

Preparation of Cu Metal-Organic Framework Nanofiltration Membrane Using 1,2-Ethanedisulfonic Acid Dihydrate

Upadhyaya, Lakshmeesha, et al. Membranes, 2020, 10(11), 313.

A mixed-matrix polyimide membrane was prepared through a non-solvent-induced phase inversion process, containing Cu(II)BTC, Cu(I/II)BTC, and Cu(I) 1,2-ethanedisulfonic acid (EDS) (Cu(I)EDS) metal-organic frameworks (MOFs). The prepared membrane has solvent resistance and mechanical stability and can be used for nanofiltration separation of toluene and n-heptane.
Direct synthesis of Cu(I)EDS
· First, a mixture of copper acetate monohydrate (270 mg, 1.35 mmol), 1,2-ethanedisulfonic acid (EDS, 290 mg, 1.52 mmol), and 4,4' bipyridine (210 mg, 1.34 mmol) was prepared in 10 mL of water.
· The solution was stirred at room temperature for 30 minutes before being transferred to a Teflon cell. The cell was sealed and placed in a stainless-steel reactor, which was then inserted into a preheated sand bath at 150 °C. After four days of reaction, the reactor was allowed to cool down naturally.
· The pH of the solution decreased from 4.2 to 3.1 during the reaction. The resulting yellow-brown crystals were filtered, washed with a mixture of water and acetone two to three times, and finally dried overnight in a vacuum oven.

1,2-Ethylenedisulfonic Acid Dihydrate Used in the Synthesis of Silver Quinoxaline Coordination Polymer

Soe, Eaindar, et al. European Journal of Inorganic Chemistry, 2019, 16, 2175-2181.

Silver(I) coordination polymers (CPs) have been widely used in conductive materials, antibacterial agents, luminescent materials and supramolecular chirality due to their structural diversity and rich physical and chemical properties. A cationic silver-based quinoxaline coordination polymer, [Ag(quinoxaline)+][- O3SCH2CH2SO3-]0.5·H2O (SLUG-37) , has been successfully developed with strong white light emission, showing potential for use as a white light LED. 1,2-Ethanesulfonic acid dihydrate is one of the important raw materials for the synthesis of SLUG-37.
Synthesis of SLUG-37
· AgCH3CO2 (0.17 g, 1.0 mmol), quinoxaline (0.17 g, 1.3 mmol), and either 1,2-ethanedisulfonate disodium salt (0.23 g, 1.0 mmol) or 1,2-ethanedisulfonic acid dihydrate (0.19 g, 1.0 mmol) were dissolved in deionized water (10 mL) in ratios of 1.0:1.3:1.0:400, respectively.
· The solution was stirred at room temperature for 15 minutes before being transferred to a 15 mL Teflon-lined autoclave filled to 2/3 capacity. The autoclave was heated in an oven at temperatures ranging from 100 to 150 °C for 1 to 5 days to complete the reaction.
· An alternative method for synthesizing SLUG-37 involved refluxing or stirring at room temperature using the same reactant ratios, with the crystals filtered after approximately 1 hour of refluxing at 70 °C or 1 day of stirring at room temperature.
