- 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
- 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.) Vacuum out oxygen : turn big end of nossle up, observe that solution does react
- 7.) Turn off vacuum and turn on nitrogen: turn little end of nossle up. Bubbles in back should appear, this means nitrogen is on
- 8.) Turn on heat to 56, switch down accordingly until it reaches 135 degrees consistently.
- 9.) If solution seems to be boiling adjust and turn down
- 10.) Solution stable at 133 degrees at 51, mark red line on it to see difference in solution level.
