Abstract

A process for the production of compounds having a structural formula <FORM:0727247/IV (b)/1> in which R is either hydrogen or an alkyl group, R1 is an alkyl group and R2 is a secondary alkyl group which may contain an aryl substituent, comprises reductively alkylating the corresponding amines having a structure <FORM:0727247/IV (b)/2> by hydrogenation in the presence of the appropriate ketone, under conditions which do not lead to the occurrence of a substantial amount of nuclear hydrogenation. The reaction is effected catalytically using a catalyst comprising copper (which may be in foraminate form or on a support such as zinc oxide, alumina, kieselguhr or pumice) or a metal of Group VIII of the periodic system such as nickel (foraminate or Raney form) or platinum (finely divided or on a support). The reduction is effected in liquid phase, conveniently in a medium of excess ketone, a ketone/amine ratio of 10 : 1 being suitable. Temperatures of 120 DEG to 200 DEG C. and pressures of 25 to 100 atmospheres may be used. In an example N-dimethyl-p-phenylene diamine (obtained by the catalytic reduction of N-dimethyl-p-nitroso-aniline) is reacted with methyl ethyl ketone and hydrogen at 50 atmospheres and 160 DEG C. to give N-dimethyl-N1-sec.-butyl-p-phenylene diamine. N-Methyl-N1-(diphenylmethyl)-p-phenylene diamine may be produced similarly by hydrogenating a mixture of N - methyl - p - phenylene diamine and benzophenone. The products are suitable for the stabilization of organic compounds liable to deterioration arising from free-radical chain reactions propagated by oxidation or polymerization, and may be added for that purpose to aldehydes, ethers, petrols, fatty oils and lubricating oils comprising esters or hydrocarbons, suitably in amounts of 0.0002 to 3 per cent by weight. Specification 508,129 is referred to. According to the Provisional Specification, R1 and R2 may also represent aryl radicals.ALSO:Amine derivatives of the formula <FORM:0727247/III/1> in which R is either hydrogen or an alkyl group, R1 is an alkyl group and R2 is a secondary alkyl group which may contain an aryl substituent are suitable for the stabilization of organic compounds liable to deterioration arising from free-radical chain reactions and for that purpose may be added to petrols, fatty oils of vegetable or animal origin comprising esters of long chain saturated or unsaturated carboxylic acids and lubricating oils comprising esters or hydrocarbons, suitably in amounts of 0.0002 to 3 per cent. by weight. Compounds of the above formula, the preparation of which is described (see Group IV (b)), include N-dimethyl-N1-sec butyl-p-phenylene diamine (shown as an antioxidant for petrol) and N-methyl-N1-(diphenylmethyl)-p-pheny. lene diamine. Specification 508,129 is referred to-According to the Provisional Specification, R1 and R2 may also represent aryl radicals.
