| titleOfInvention | Morpholyl-dihydroquinoline derivatives and their use as antiozonants and antioxidants for rubber |
| abstract | The invention comprises compounds of the general formula: <FORM:0960730/C1/1> in which R is hydrogen or a C1-C4 alkyl group and R1 is a C 1-C4 alkyl group. They may be prepared by reacting p-chloronitrobenzene with at least one equivalent of morpholine at 120-150 DEG C., catalytically hydrogenating the resultant nitro compound, reacting the resulting N-(p-aminophenyl)-morpholin with a ketone of formula CH3COR1 at about 100 DEG C. under superatmospheric pressure in the presence of iodine and distilling off the excess ketone. If R is alkyl it may be introduced by treating the product with an alkyl halide. An example is given of the preparation of 6-morpholyl-2, 2, 4-trimethyl-1, 2-dihydroquinoline from N-(p-amino phenyl) morpholine (which is prepared from N-(p-nitrophenyl) morpholine) and acetone. Other ketones which may be used are, for example, 2-butanone and 3-methyl-2-butanone.ALSO:New morpholine derivatives of formula: <FORM:0960730/C3/1> in which R is hydrogen or a C1-C4 alkyl group and R1 is a C1-C4 alkyl group are used as antioxidants and antiazonants for synthetic and natural rubbers. They may be incorporated with the rubber by known methods, for example by milling on a roll mill or Banbury mixer. They are suitably added in an amount of from 0.5 to 5% by weight of the rubber, together with known fillers, stabilizers and vulcanizing agents before the rubber is cured. |
