I want to perform electropolymerization of Aniline to prepare polyaniline. Should I necessarily vacuum distillate it prior to use? If yes, what is the procedure?
I agree with Dr. H.S.Rao response.However, there is no need to recrystallize the aniline to remove the sulphur containing impurities. We are distilling the aniline for determination of aniline point in petroleum products. The fresh bottle is distilled without using the anhydrous calcium sulphate, but used aniline bottle is to be kept overnight with 3-4 grams of anhydrous calcium sulphate or sodium sulphate to remove moisture before distillation. To confirm the purity of aniline the aniline point of distilled aniline should be come 69.3 +- 0.2 Deg.C. Aniline point is determined using n-heptane (5 ml.)and aniline (5 ml.) method no. ASTM D-611.
it does not improve the properties of electropolymerized polyaniline if distilling the aniline before polymerizing
Dear Dr. Bernhard Wessling,
What about the properties of chemically polymerized polyaniline; Will it be affected by vacuum distillation of aniline?
"affected" would mean: "any negative influence?" No, there is negative influence, but also no positive effect.
