Tasks for February 25

  • To make new fibers and extract them
  • To analyze the reaction from Feb. 24

Filtration and Analysis of polymerization of aniline

  • The reaction products were first filtered and rinsed with distilled water.
  • Note: a Whatmann nylon membrane filter (0.2 μm) was used.
  • Methanol was used to dissolve polyaniline and the filtrate was recovered in a separate flask.
  • The filtrate was poured onto a watch glass and allowed to evaporate.

Watch glass weight= 52.59842 g <br.> Final watch glass weight= 52.60167 g <br.> Recoverable weight= <br.> Percent yield= (0.00325/0.5)×100%=0.65%
