    Abstract: PROBLEM TO BE SOLVED: To produce a stable benzophenone imine free from a reverse reaction to form benzophenone during storage by distilling ammonia and also removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reaction. SOLUTION: This method is composed of the processes distilling ammonia and removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reactor generated by catalytic reaction of a benzophenone of the formula [R and R are independently a halogen, hydroxy, a 6-10C aryl, a 1-12C alkyl, etc.; (m) and (n) are each independently an integer of 0-5] and ammonia. The distillation is preferably carried out at 20-200 deg.C under a pressure of 1-1,000 mbar.

    Abstract: A process for the production of 4,4'-dihalo-diphenyl- sulphones (DHDPSO) comprises reacting chloro-, bromo- or fluoro- benzenes with 4-halophenylsulphonyl chlorides of formula (I); in which X = chlorine, bromine or fluorine. The reaction is carried out in the liquid phase at elevated temperature in presence of solid catalysts with acid centres, comprising (K1) layer silicates with negative layer charges neutralised by protons and essentially not doped with Lewis acids, (K2) zeolites in the acidic H-form, or (K3) mixed oxides with acid centres, consisting of a combination of (a) oxides of titanium, zirconium, hafnium, tin, iron or chromium(III) with (b) oxides of vanadium, chromium(VI), molybdenum, tungsten or scandium, or sulphated or phosphatised oxides of group (a), such mixed oxides having been calcined at 450-800 deg C after combination. Preferably type (K1) comprises aluminium silicate in which part of the silicon is replaced by aluminium and/or part of the Al is replaced by magnesium, especially a montmorillonite. Type (K2) comprises zeolites of structural types MFI, MEL, BOG, BEA, EMT, MOR, FAU, MTW, LTL, NES, CON or MCM 22, especially 12-ring zeolites of the BETA, Y, EMT or mordenite type, or 10-ring zeolites of the pentasil type. Type (K3) may be super-acid mixed oxides, preferably with group (a) oxides and group (b) oxides in a mol ratio of (70:30)-(98:2). The process comprises reacting chlorobenzene (PhCl) with 4-chlorophenyl-sulphonyl chloride (ClPhSOCl) in a mol ratio of 1-100, preferably using excess PhCl, at 100-250 deg C and 1-50 bar, preferably at boiling pt. under normal or autogenous pressure. The catalyst is in the form of a solid bed, and the reaction may be carried out as a continuous process in which excess PhCl is returned to the reactor.
