DPNI: 06-26-13

  • 1.) Add solids 1,4,5,8 Naphthalenetetracarboxylic dianhydride (.805 g, 3.00 mmol) and 4-aminopyridine (.847 g, 6.00 mmol)to round bottom flask (I added .8054 g of 1,4,5,8 Naphthalenetetracarboxylic dianhydride, and .8479 g of 4-aminopyridine)
  • 2.) Add 150 mL of solvent (DMA) ~keep under hood~
  • 3.) Add Stir Bar to solution
  • 4.) Put under spout and raise black knob until there is enough pressure to hold it in place
  • 5.) Begin to stir
  • 6.) If attached to condenser, turn on water very slightly
  • 7.) Turn on nitrogen: ensure bubbles are about 1 every 4 seconds. (Turn little end of nossle up)
  • 8.) Turn on heat to 50, switch down accordingly until it reaches 135 degrees consistently.
  • 9.) If solution seems to be boiling adjust and turn down
  • 10.) Solution stable at 135 degrees at 35, mark red line on it to see difference in solution level.

  • 11.) Turn off nitrogen and water, Cool to Room Temperature
  • 12.) Not enough diethyl ether, took 400 mL of diethyl ether (instead of the required 600 mL) and poured 2/3's of DPNI solution into the 400 mL of diethyl ether.
  • 13.) Filter out
