The Effect of the Nitrogen-containing Compounds e.g. Ammonia-Resol, upon the Condensation Reaction of 2, 4- and 2, 6-Xylenols with Formaldehyde

Abstract

Previously, it was revealed that the nitrogen-containing compounds formed at the initial step of the reactions of 2, 4- and 2, 6-xylenol with formaldehyde catalyzed by ammonia showed a noticeable effect upon the reaction occurred subsequently, The present paper describes(I)a kinetic study of the reactions between the above xylenols and formaldehyde in the presence of oxazine and tribenzylamino type compounds dereived from the xyleftols, and (II) the products formed, and thier changes with time, examined by means of NMR spectroscopy.
Different behaviors of the nitrogen-containing compounds have demonstrated in the ondensation reaction, although the details are still obscure.
