    Abstract: Pure isophorone-diamine (IPDA) with a cis/trans isomer ratio (CTR) of at least 73/27 is obtained by (a) making crude IPDA with a CTR below 73/27, (b) purifying and separating into fractions with CTR of at least 73/27 (b1) and below 63/37 (b2), (c) isomerizing (b2) in presence of hydrogen, ammonia and catalyst to give IPDA with a CTR of 63/37-66/34 which is recycled to stage (a). A method (M1) for the production of substantially pure 3-aminomethyl-3,5,5-trimethyl cyclohexylamine (isophorone-diamine; IPDA) with a cis/trans isomer ratio (CTR) of at least 73/27 involves: (a) preparation of crude IPDA with a CTR of less than 73/27, (b) purification and separation to give fractions (b1) with a CTR of at least 73/27 and (b2) with a CTR of less than 63/27 and (c) isomerization of (b2) in presence of hydrogen, ammonia and a hydrogenation catalyst to give IPDA with a CTR of 63/37-66/34 which is then recycled to stage (a). An Independent claim is also included for a method (M2) for the production of IPDA with a CTR in the range 63/37 to 66/34 by reacting IPDA with any CTR value with hydrogen and ammonia in presence of a hydrogenation catalyst.

    Abstract: The invention relates to a method for the production of acrylic acid or methacrylic acid, wherein propane or isobutane a reacted with molecular oxygen in the gas phase in a fluidized bed reactor containing a catalyst, wherein the catalyst contains a multi-metal oxide comprising a molybdenum, tellurium and/or antimony, vanadium and niobium. A catalyst activator containing at least one tellurium compound is added during the reaction.

    Abstract: PCT No. PCT/EP98/00705 Sec. 371 Date Jul. 28, 1999 Sec. 102(e) Date Jul. 28, 1999 PCT Filed Feb. 9, 1998 PCT Pub. No. WO98/37054 PCT Pub. Date Aug. 27, 1998A process for the isolation of 3-[2-chloro-4-(trifluoromethyl)phenoxy]benzoic acid of the formula I from an aqueous solution of its metal salt comprises a) reacting the metal salt of 3-[2-chloro-4-(trifluoromethyl)phenoxy]benzoic acid with an organic or inorganic acid; b) heating the reaction mixture until a liquid two-phase system of organic and aqueous phase has formed; and c) separating the organic phase from the aqueous phase.
