ABSTRACT:
It has been found that the following materials act as catalysts for the conversion of PETC to PETA by the ammonolysis of PETC in methanolic ammonia: (a) amine acid addition salts and quaternary ammonium halides and hydroxides, (b) tertiary amines, (c) olefin epoxides, (d) 8-hydroxyquinolines, (e) amine phenoxides, (f) quaternary hydroxyalkyl ammonium hydroxides, and (g) glycidyl halides and ethers. The preferred catalysts, according to this invention, include tetramethyl ammonium chloride, benzyl dimethylamine, dodecyl dimethylamine and 1,2-epoxy decane.
