Abstract: In an improved process for preparing caprolactam by heating 6-aminocaproic acid, an ester or amide or mixture thereof in the presence of an inert reaction medium which is liquid under the reaction conditions and has a boiling point above that of caprolactam, the improvement comprises using as the reaction medium a hydrocarbon, maintaining a temperature of from 150 DEG to 350 DEG C., charging the 6-aminocaproic acid, ester, amide or mixture thereof at a rate commensurate with their rate of conversion, and separating caprolactam from the reaction mixture at a rate commensurate with its rate of formation.

Abstract: Prodn. of pentenoic acid esters (I) comprises heating 3- and/or 4-formylvaleric acid esters (II) to 50-400 deg. C in presence of a catalyst ofontg. a least one element sub-group B. More specifically (II) are the methyl esters and supported catalysts ontg. 0.01-10 wt. % metal (based on total catalyst), esp. Ru, Rh, Pd, Pt, Ir and/or OS, are used. The catalyst may also contain (a) at least one of Fe, Co and Ni, and/or (b) a metal of sub-gps. 1-7.

Abstract: Prodn. of 2(5H)- furanones of formula (I) comprises reacting 3-formylcarboxylic acid or esters O = C(H)-CH(R1)-C(H)(R2) 0 = C(H)-C(H)(R1)-C(H)(R2)-(O)C-OR3 (II) in presence of acid catalyst at 100-450 deg. C. R1 and R2 = H, 1-6C alkyl, 5-6C cycloalkyl, 7-12C aralkyl or aryl; R3 = H, 1-12C alkyl, 5-6C cycloalkyl, 7-12C aralkyl or aryl. Acid catalysts are acidic oxides of B, AR, Si, P or metals of sub-groups IV-VI,or natural or synthetic zeolites. The catalysts are SiO2, Al2O3, B2O3, TiO2, V2O5, Cr2O6, or X Y or pentasil type zeolites. In (II), R1 and R2 are 1-6C alkyl and R3 = 1-12C alkyl. Reaction is at 200-350 deg. C and 1-50 (pref. 1-5) bar, and lactonisation is in presence of water and/or 1-4C alcohol. Where a heterogeneous catalyst is used, it is 0.5-20 wt. % on (II) for liq. phase reaction, or 0.1-10 (esp. 0.1-5)g (II) is used per g catalyst per hr., for gas phase reaction. Reaction is opt. in presence of 0.1-50 (pref. 0.5-20) moles solvent per mole (II).
