Abstract
An N-alkyl or N-aralkyl phenthiazine is prepared by reacting a corresponding N-alkali metal phenthiazine with an alkyl or aralkyl halide in the presence of tetrahydrofuran. The phenthiazine may be alkyl, aralkyl or hydroxy substituted, and the 9-sulphur atom may be oxygenated. The N-alkali metal phenthiazine may be prepared by reacting a phenthiazine with a dispersion of an alkali metal in a suitable solvent. Specifications 824,521 and 873,064 are referred to.ALSO:A mineral or synthetic lubricating oil composition contains as an antioxidant an N-alkyl or N-aralkyl phenthiazine prepared by reacting a corresponding N-alkali metal phenthiazine with an alkyl or aralkyl halide in the presence of tetrahydrofuran. The phenthiazine ring may be alkyl, aralkyl or hydroxy substituted, and the 9-sulphur atom may be oxgygenated. Synthetic lubricating oils mentioned are copolymers of alkylene glycols and alkylene oxides, organic esters, or those prepared by the processes of Specification 873,064. Specification 824,521 also is referred to.
