  • Aromatic bismaleimide derivatives and process for preparing same
    Patent number: 5013848
    Abstract: A novel aromatic bismaleimide of the formula (I): ##STR1## wherein X is ##STR2## where R.sub.1 R.sub.2, R.sub.3 and R.sub.4 are a hydrogen atom or a methyl group. The bismaleimide is prepared by reacting an aromatic diamine having the formula (II): ##STR3## wherein X is the same as in the formula (I), with maleic anhydride and then conducting the ring-closing reaction of the resultant aromatic bismaleamic acid.

  • Process for producing aminobenzylamines
    Patent number: 4751328
    Abstract: Aminobenzylamines are produced by catalytically reducing o-, m- or p-nitrobenzaldoxime in an organic solvent in the presence of a compound selected from the group consisting of (a) boric acid, phosphoric acid and/or anhydrides thereof, (b) CO.sub.2 gas and (c) an organic acid. The starting material, nitrobenzaldoxime is produced by reaction of the corresponding nitrobenzaldehyde with hydroxylamine.
