Aniline → Benzoxazines

Participants

Reaction Conditions

Reaction Steps

1 mol of tertiary butylphenol, 2.2 mol of p-formaldehyde, and 1.1 mol of aniline were mixed and stirred without a solvent at 100° C. for 1 hour to produce a crude product. The crude product was washed twice with a 1N NaOH aqueous solution and once with distilled water. The washed crude product was then dried with magnesium sulfate. Then, the resultant was filtered. The resultant was dried in a vacuum to obtain the benzoxazine monomer represented by Formula 4. The benzoxazine monomer of Formula 4 was produced with a 95% yield. NMR spectrum of the benzoxazine monomer of Formula 4 is shown in FIG. 10.
