To quickly assess the difficulty of the text, read a short excerpt:
Triphenylcarbinol, (C 6 H 5 ) 3 COH, a white crystalline solid melting at 159. This may also be prepared by the direct oxida- tion of triphenylmethane with chromic acid or by the Grignard reaction from benzophenone and magnesium phenyl bromide : M Br H 2 o -i(C 6 H 5 ) 3 COH + Mg(OH)Br The magenta dyestuffs are hydrochlorides of aminotriphenyl- carbinols. Triphenylcarbinol dissolves in concentrated sulphuric acid, forming an intensely yellow solution. . CHAPTER XV THE DI- AND TRIPHENYLMETHANE D...YES Diphenylmethane Colours THE chief dyestuff derived from diphenylmethane is auramine, which is an important yellow colouring matter. Auramine is prepared by heating Michler's ketone (p. 84) with zinc chloride in a current of ammonia : / C 6 H 4 NMe 2, C 6 H 4 NMe 2 CO +NH >C The intense colour is only produced when the base is dis- solved in acid and the salt therefore probably possesses the = N(CH3)2C1 quinonoid formula, H 2 N. C'" ^ ' (p. 97). ^ \ N(CHs)2 Triphenylmethane Colours The constitutions of these dyestuffs and their chief derivatives are most easily deduced from a study of rosaniline (magenta, fuchsine) and para-rosaniline, the first dyestuffs of this series to be isolated and investigated.
