Fourier Transform IR Spectroscopy Study of the Degradation of Pyromellitic Acid Diester
Volume 41, Number 3 (April 1987) Page 479-482
Sanchez, L.A.; Wedgewood, A.R.
The degradation of pyromellitic acid diester (PMDE) was studied by transmission Fourier transform IR spectroscopy (FT-IR). Reaction temperatures were varied from room temperature to 280°C, and the effect of temperature upon the observed vibrational modes of PMDE was monitored and analyzed. The formation of both a cyclic and a noncyclic anhydride was observed.
