The API-IL benzalkonium salicylate was prepared from benzyldimethyldodecylammoniumchloride (benzalkonium chloride) and sodium salicylate according to a procedure similar tothat described in the literature [8]. Sodium salicylate (0.93 g, 5.8 mmol) and benzyldimethyldodecylammoniumchloride (2.05 g, 5.8 mmol) were dissolved in 20 mL of acetone/H2O(1:1). The reaction mixture was stirred overnight at room temperature. The remaining suspensionwas diluted with 20 mL of distilled water. The product was extracted with dichloromethane.Sodium chloride as a byproduct was removed by washing the dichloromethane phase successivelywith water. The presence of chloride ions in the washings was detected using AgNO3solution. The dichloromethane was evaporated under reduced pressure. The obtained API-ILwas further dried at 343 K in vacuum for 8 h. The water content of the API-IL was determinedby a Karl-Fischer measurement, and the value was about 350 ppm. The synthesized API-ILwas characterized by 1H NMR (Bruker DPX) and IR (Nicolet IR-470).The characterization values obtained are: IR (KBr, cm-1): 3437(s), 3027(w), 2921(s),2852(s), 1638(s), 1590(s), 1484(s), 1456(s), 1219(s), 1137(m), 758(m), 735(m);1H NMR:(400 MHz, CDCl3)delta in ppm: delta 7.97 (dd, J = 7.7, 1.7 Hz, 1H), 7.48 (m, 6H), 6.87 (d,J = 8.2 Hz, 1H), 6.76 (t, J = 7.4 Hz, 1H), 4.82 (s, 2H), 3.36 (m, 2H), 3.21 (s, 6H), 1.74 (s, 2H),1.24 (d, J = 7.4 Hz, 18H), 0.88 (t, J = 6.8 Hz, 3H). The 1H NMR spectra of BaSal is presentedin Fig. S1 of the Supplementary Material.Thermal stability was measured on a STA 409 PC simultaneous thermal analyzer (Germany)in the range of 303-773 K at a heating rate of 10 K¡¤min-1 under an air environment. Itcan be seen from Supplementary Fig. S2 that BaSal has good thermal stability with the lowdecomposition temperature of 454 K., 139-07-1
The synthetic route of 139-07-1 has been constantly updated, and we look forward to future research findings.
