Abstract | PURPOSE:To obtain the titled compound useful as a synthetic resin raw material, resin additive, dye, etc., in high yield and selectivity, by reacting a diisopropylbenzene dicarbinol compound with an aniline compound in the presence of a synthetic zeolite catalyst. CONSTITUTION:A bis(p-aminocumyl)benzene compound can be produced by reacting a diisopropylbenzene dicarbinol compound of formula I (Y is halogen, amino, lower alkyl, etc.; m is 0-4) with an aniline compound of formula II (R1 and R2 are H or 1-3C alkyl; X is halogen or 1-3C alkyl; n is 0-4) in the presence of a synthetic zeolite catalyst of formula III (e.g. zeolite-X, zeolite- Y, zeolite-L, mordenite, etc.). It is preferable to carry out the reaction at a high temperature (i.e. at 220-260 deg.C) under pressure to increase the yield of the objective compound. The yield and selectivity are improved compared with conventional process using activated clay as a catalyst. |
