Abstract: This invention relates to the intramolecular oxidation and reduction of aromatic hydrocarbons containing at least one methyl group and a nitro group ortho to the methyl group. Further, it relates to preparing methyl o-amino arylcarboxylates and aromatic amines. The process comprises reacting aromatic hydrocarbons having at least one methyl group and a nitro group ortho to the methyl group in a solvent at a temperature of about 450.degree. to 750.degree. C. When the solvent is methanol, methyl o-amino arylcarboxylates useful in anesthetics, printing inks for polyethylene, and useful in the manufacture of azo dyes are produced. Novel substituted methyl anthranilates have been produced which have the foregoing uses. When no solvent is used or the solvent is benzene, cyclohexane, toluene, hexafluorobenzene or any other non-reactive solvent, the compounds are demethylated and aromatic amines are produced.

Abstract: Partial esters of polyhydroxy compounds and combinations thereof with organophosphorus compounds have been found to be effective stabilizers for polyolefins made in processes wherein such polymers are not subjected to extensive removal of process produced impurities during or subsequent to the polymerization process.
