Abstract
Phenoxyphenyl (phenoxy)-benzoates are useful as lubricantsALSO:The invention comprises phenoxy phenyl-(phenoxy)-benzoates which may be made by reacting one or more phenoxyphenols with one or more phenoxy benzoyl halides until the evolution of hydrogen halide ceases. The phenoxyphenol may be prepared by reacting a halo-aniline (preferably chloro- or bromo-) with an alkali metal (preferably potassium or sodium) phenate in the presence of copper or copper bronze at elevated temperature (e.g. 180-300 DEG C.) to produce phenoxyaniline, diazotizing and converting the diazonium halide to a hydroxy group, for example by adding to boiling sulphuric acid. The phenoxybenzoyl halide is made by the action of thionyl halide on phenoxy benzoic acid which may be prepared by reacting an alkali metal (e.g. K or Na) cresate with a phenyl halide (e.g. Cl or Br) in the presence of copper or copper bronze and oxidizing the phenoxy toluene formed to phenoxy benzoic acid, for example with aqueous permanganate. The preparation of m-phenoxyphenyl (m-phenoxy)-benzoate is described.
