Process for preparing aromatic polyamine mixtures |
| abstract |
Production of aromatic polyamine mixtures contg. cpds. of formula: H2NACH2BNH2(I) (where, A and B = 1,4-phenylene residues which can have 1-4 substits. chosen from 1-20C alkyls and halogens) comprises converting a cpd. of formula: HANHCH2NHBH (IV) and/or a cpd. of formula HANHCH2BNH2 (V) (where, A and B = as above) at a temp. of 20-200[deg]C in the presence of a heterogeneous inorganic catalyst chosen from: (a) oxides of 3-10 group element which can be acid-activated; (b) a clay doped with an oxide of a 2-13 group element or lanthanide which an be acid-activated; and (c) opt. acid-activated layered silicates acidity of below pK3 = 0.5 of more than 0.05 mmol/g catalyst. - |
