| titleOfInvention | Derivatives of 2,2-bis-(3-aminophenyl)hexafluoropropane and process for the preparation of 2,2-bis-(3,4-diaminophenyl) hexafluoropropane |
| abstract | Abstract The invention relates to compounds of the formula wherein R1 is hydrogen or an acyl group in which a non-aromatic hydrocarbon group of 1 to 6 carbon atoms is attached to the CO-group and R2 is H or NO2, if R1 is an acyl group, or is NO2, if R1 is hydrogen. The invention further relates to a process for the production of 2,2-bis-(3,4-diaminophenyl)-hexafluoropropane of the formula which comprises a) acylating 2,2-bis-(3-aminophenyl)-hexafluoropropane, under conditions conventional for acylations, to yield a 2,2-bis-(3-acylamidophenyl)-hexafluoropropane, the acyl group of which is free from aromatic groups, b) nitrating the 2,2-bis-(3-acylamidophenyl)-hexafluoro-propane, under conditions conventional for nitrations, to yield 2,2-bis-(3-acylamido-4-nitrophenyl)-hexafluoropropane, c) deacylating the 2,2-bis-(3-acylamido-4-nitrophenyl)-hexafluoropropane, under conditions conventional for deacylations, to yield 2,2-bis-(3-amino-4-nitrophenyl)-hexafluoropropane, d) reducing this compound, under conditions conventional for the reduction of nitro compounds, to yield 2,2-bis-(3,4-diaminophenyl)-hexafluoropropane, and e) isolating this compound or subjecting it to a puri-fication by converting it into a solution of one of its salts, adsorbing contaminations at an adsorption agent and precipitating the 2,2-bis-(3,4-diaminophenyl)-hexafluoropropane by addition of a base. The compound so produced is useful as a monomer building block for polymers. |
