Abstract: Alkanediol ortho- and meta-diamino benzoates are prepared by reacting either ortho- or meta-amino benzoic acid esters with an alkanediol in the presence of a transesterification catalyst. The ortho-diamine may alternatively be prepared by reacting isatoic anhydride with the alkanediol. These alkanediol ortho- and meta-diamino benzoates are useful in the curing of urethane prepolymers to produce novel polyurethane urea elastomers.

Abstract: A method for preparing substituted triazines includes reacting a phenylazoaniline with a cyanuric halide to produce a (phenylazo) phenylamino-1,3,5-triazine, which is then reduced to form an aminoanilino-1,3,5-triazine. The aminoanilino-1,3,5-triazine can be alkylated under reducing conditions to produce an N-alkyl-phenylenediamino-1,3,5-triazine such as 2,4,5-tris-[N-alkyl-p-phenylenediamino]-1,3,5-triazine, which is useful as an antiozonant in rubber and other polymer formulations.

Abstract: Processes of preparing para substituted phenylamines, such as, p-phenylenediamines, and particularly, p-aminodiphenylamine.
