Embodiment 1
[0031] Embodiment 1: used silver nitrate (analytically pure), its main component (%) is: AgNO 3 ≥99.8%, water insoluble ≤0.005%, chloride ≤0.001%, sulfate ≤0.004%, Fe≤0.0004%, Cu≤0.001%, Pb≤0.001%, hydrochloric acid non-precipitate ≤0.02%.
[0032] Measure 6ml of 0.5M silver nitrate solution prepared in advance into a beaker, add 5.35g of n-hexanol, 150ml of cyclohexane and 2.16g of sodium lauryl sulfate, place it in ultrasonic cleaning, and ultrasonically disperse it to form a translucent reverse glue Beam solution A. Weigh a certain amount of aniline and dissolve it in 1M nitric acid solution, configure 0.5M aniline / nitric acid solution, measure 6ml of aniline / nitric acid solution in a beaker, add 5.35g n-hexanol, 150ml cyclohexane and 2.16g dodecyl Sodium sulfate, as above, prepare an equal volume of reverse micellar solution B. Mix the reverse micellar solutions A and B, and magnetically stir for 10 minutes to make them evenly mixed. Cover the mouth of the beaker with a...
Embodiment 2
[0035]Measure 6ml of 0.2M silver nitrate solution prepared in advance into a beaker, add 5.35g of n-hexanol, 150ml of cyclohexane and 2.16g of sodium lauryl sulfate, and ultrasonically disperse to form reverse micellar solution A. Prepare 0.2M aniline / nitric acid solution, measure 4ml of aniline / nitric acid solution, and prepare an equal volume of reverse micellar solution B as above. Mix the reverse micellar solutions A and B, and magnetically stir to make them evenly mixed. Cover the mouth of the beaker with a watch glass, place the reaction system in a fume hood, and keep the purple light lamp at a vertical distance of 10 cm from the liquid surface. Turn on the purple light, and magnetically stir the reaction at room temperature for 20 h. Add methanol, stir for 3h to break the emulsion, filter and wash until the filtrate is colorless and foam-free. The filter cake was dispersed into 4M hydrochloric acid solution, stirred for 2 h for re-doping, then centrifuged and washed ...
Embodiment 3
[0039] Measure 6ml of 0.5M silver nitrate solution prepared in advance into a beaker, add 5.35g of n-hexanol, 150ml of cyclohexane and 2.16g of sodium lauryl sulfate, and ultrasonically disperse to form reverse micellar solution A. Prepare 0.5M aniline / nitric acid solution, measure 4ml of aniline / nitric acid solution in a beaker, add 5.35g n-hexanol, 150ml cyclohexane and 2.16g sodium dodecyl sulfate, the same as the reverse micellar solution B configured above. Mix the reverse micellar solutions A and B, and magnetically stir to make them evenly mixed. Cover the mouth of the beaker with a watch glass, place the reaction system in a fume hood, and keep the purple light lamp at a vertical distance of 10 cm from the liquid surface. Turn on the purple light, and magnetically stir the reaction at room temperature for 20 h. Add methanol, stir for 3h to break the emulsion, filter and wash until the filtrate is colorless and foam-free. The filter cake was dispersed into 4M sulfuric...
