Abstract
m - Acetaminophenyl - b - naphthylamine is prepared by heating one mol of mono-b -naphthyl-m-phenylenediamine with one mol of acetic anhydride for two hours on a steam bath, extracting with water, and crystallizing from toluene; p - acetaminodiphenylamine, and acetyl - b - naphthyl - m - phenylenediamine are made in a similar manner. m-(p-Toluene-sulphonylamino) - phenyl - b - naphthylamine is prepared by dissolving one mol of mono-b -naphthyl-m-phenylenediamine in alcohol, adding separately with stirring one mol of p-toluenesulphonyl chloride in alcohol and one mol of sodium acetate in alcohol, and refluxing for one hour on a steam bath. p-(p-Toluenesulphonylamino) - diphenylamine and p - (p - toluenesulphonylamino) - phenyl - p - tolylamine are prepared in a similar way. Other sulphonyl chlorides may be employed, one specified being b -naphthalene-sulphonyl chloride; other aminodiaryl amines specified are p-amino-diphenylamine, p - aminophenyltolylamines, mono-b -naphthyl-p-phenylenediamine, mono-a - naphthyl - p - phenylenediamine, mono - b - naphthyl - m - phenylenediamine, mono - a - naphthyl-m-phenylenediamine; acidyl groupings of formic acetic, butyric, stearic, benzoic, furoic, carbonic, phthalic, succinic, maleic, malonic, benzenesulphonic, toluenesulphonic, and oxalic acids may be employed.ALSO:The ageing of rubber is improved by the addition of the reaction products of amino diarylamines and acid anhydrides or acid chlorides having the probable formula (R1-NH-R2-NH)w-Y in which R1 = aryl, R2 = arylene, w = 1 or 2, and Y = an acidyl group. Numerous compounds and their preparation are described. m-acetamino-phenyl-b -naphthylamine is prepared by heating one mole of mono-b -naphthyl-m-phenylene diamine with one mole of acetic anhydride for two hours on a steam bath, extracting with water, and crystallizing from toluene. p-acetamino diphenylamine, and acetyl b -naphthyl m-phenylene diamine are made in a similar manner. m-(p-toluene sulphonylamino) phenyl b -naphthylamine is prepared by dissolving one mole of mono b -naphthyl-m-phenylene diamine in 3 litres of alcohol, adding separately with stirring one mole of p-toluene sulphonyl chloride in alcohol and one mole of sodium acetate in alcohol, and refluxing for one hour on a steam bath. p-(p-toluene sulphonylamino) diphenylamine, and p-(p-toluene sulphonylamino)-phenyl-p-tolylamine are prepared in a similar way. Other sulphonyl chlorides may be employed one specified being b -naphthalene sulphonyl chloride: other aminodiarylamines specified are p-amino-diphenylamine, p-aminophenyl tolylamines, mono-b -naphthyl-p-phenylene diamine, mono-a -naphthyl-p-phenylene diamine, mono-b -naphthyl-m-phenylene diamine, mono-a -naphthyl-m-phenylene diamine: acidyl groupings of formic, acetic, butyric, stearic, benzoic, furoic, carbonic, phthalic, succinic, maleic, malonic, benzenesulphonic, toluene sulphonic, and oxalic acids may be employed.
