Title: Manufacture of ortho benzyl-salicylic acid and derivatives thereof
IPC: C07C51/15
Filed: 1935-05-31
Abstract: o-Benzyl-salicylic acid is made by reacting carbon dioxide with an alkali salt of o-benzyl-phenol in absence of water and in presence or absence of a liquid diluent or by condensing a benzyl halide with salicylic acid or a salt thereof.  Preferably a mixture of o- and p-benzyl phenols (obtained from benzyl chloride and phenol or sodium phenolate) is used as starting material and treated with alkali in an inert organic solvent, such as xylene, toluene, chlorbenzene or o-dichlorbenzene in which the alkali-o-benzyl-phenate is soluble, the mixture is freed from water, the insoluble p-benzyl-phenate filtered off, and the filtrate used directly for the carbonation or acidified to recover the o-phenate.  The o and p-benzyl phenols referred to may be separated by fractional distillation.  The o-benzyl-salicylic acid may be converted to a derivative such as its chloride, by treatment with thionyl chloride, phosphorus trichloride or oxychloride, or other inorganic acid chloride, or its acetic ester, which has analgesic and antipyretic properties, by treatment with an acetylating agent such as acetic anhydride, or into arylides useful as coupling components for azo-dyes by reaction of the chloride with aromatic amines.  In an example, sodium o-benzyl-phenate, alone, or in solution in o-dichlor-benzene is treated with carbon dioxide at 150--180 DEG  C. and acidified, or alternatively salicylic acid or a salt thereof is heated with benzyl chloride in presence of zinc chloride or other condensing agent.  The acetic ester and the acid chloride of the o-benzyl-salicylic acid so obtained are described, the latter being obtained from the dry acid or a salt thereof and thionyl chloride or phosphorus trichloride.  The acid chloride may be reacted with aniline or a substitution produce such as chloraniline to give arylides which couple with diazotized amines in p-position to the hydroxyl group, to give dyes such as those of the "Rapidogen" (Registered Trade Mark) type.
