| titleOfInvention | Preparation of 3-(trifluoromethyl)-phenols |
| abstract | A phenol having the general formula <FORM:0934577/IV(a)/1> wherein R is a hydrogen or halogen atom or an alkyl, aryl or nitro radical is prepared by diazotising 3-(trifluoromethyl)-4-R-aniline to form a corresponding diazonium salt, hydrolysing the diazonium salt with a boiling mixture of at least 100 ml. of xylene per mole of diazonium salt and aqueous copper sulphate solution containing at least 10g. of copper sulphate pentahydrate per mole of diazonium salt, and subsequently recovering the phenol. The group R is exemplified by chlorine and bromine atoms; straight or branched chain alkyl radicals having 1 to 12 carbon atoms, e.g. methyl, ethyl, propyl, butyl, hexyl, dodecyl and isobutyl radicals; phenyl, naphthyl or alkyl substituted phenyl and naphthyl radicals, e.g. p-tolyl. 3-(Trifluoromethyl)-4-nitro-aniline is prepared by hydrolysing 3-(trifluoromethyl)-4-nitro-acetanilide with a mixture of concentrated sulphuric acid and water. |
