METHOD OF PRODUCING DI(4-CYANOPHENYL)METHANE

摘要

FIELD: chemistry.;SUBSTANCE: according to the disclosed method, di(4-cyanphenyl)methane is obtained from di(4-aminophenyl)methane. The method includes a diazotation step and is characterised by that the step for substituting diazo groups with nitrile groups is carried out at temperature of 75-80°C under the action of a copper-cyanide complex solution obtained from an alkali metal cyanide and copper sulphate in molar ratio of 4:1.;EFFECT: method enables to obtain a pure product with stable output.;2 ex
