Application of 6052-10-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 6052-10-4 name is 4,4′-(Ethane-1,2-diylbis(oxy))dianiline, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
The reatcion of 4-(4-hexyloxybenzoyloxy) benzaldehyde (22 mmol) in anhydrous EtOH(50 mL) with [1,2-bis(4-aminophenoxy)ethane (11 mmol) in the presence of PTSA[3, 21, 22]. The reaction mixture was stirred for 16 hr at the room temperature. Thecrude precipitate was collected by filtration and purified by the recrystallization of bothchloroform and ethyl acetate solvents. The prepared HBPE-1 was confirmed by 1H-NMR. 1H-NMR (CDCl3, ppm): delta 0.94-0.85 (t, 6H, -CH3), 1.50-1.24 (m, 12H, -(CH2)3-), 1.84-1.79(m, 4H, -CH2CH2O-), 4.07-4.02 (t, 4H, -CH2CH2O-), 4.37 (s, 4H, -OCH2-), 7.02-6.96 (t,8H, Ar-H), 7.33-7.24 (d, 8H, Ar-H), 7.97-7.94 (d, 4H, Ar-H), 8.16-8.13 (d, 4H, Ar-H), 8.49(s, 2H, -CH = N).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4,4′-(Ethane-1,2-diylbis(oxy))dianiline, and friends who are interested can also refer to it.
