Abstract: Process for the preparation of dialkyl carbonates of the general formula I in which R represents a C1- to C10-alkyl group, by reacting the alcohols R OH with a gaseous carbon monoxide/oxygen mixture in the presence of a copper catalyst and of a cosolvent, at increased temperature and under increased pressure, in which the cosolvent used is a cyclic urea of the general formula II in which n is the number 2, 3 or 4 and R represents hydrogen or a C1- to C4-alkyl group.

Abstract: Prodn. of 5-formylvalerate esters (I) is carried out by : (a) hydroformylation of pentenate esters (II) with CO and H2 at elevated temp. and pressure in the presence of carbonyl complexes (III) of gp. VIII metals, to give a mixt. (IV) of 5-, 4- and 3-formylvalerate esters; (b) sepn. of (I) from (IV), leaving a mixt. (V) of 4- and 3-formylvalerate esters; (c) catalytic cracking of (V) at 50-400 deg. C, to give (II), which (d) are recirculated to stage (a). In stage (a), the Co concn. is pref. 0.05-0.3 mole-% w.r.t. (II), the (II) conversion is 10-50% and the temp. 60-160 deg. C. In stage (c), the catalyst pref. contains gp. VIII metal(s) and pref. is a supported catalyst contg. at least 2 gp. VIII noble metals or at least one gp. VIII noble metal plus Fe, Co and/or Ni. Pref. it may also contain Cu, Ag, Zn, Ti, V, Cr, Mo, W, Mn and/or Re. Cracking is carried out at 60-350 deg. C in (gas contg.) O2, pref. with a (V):O2 molar ratio of 1:0.05-3 and opt. in a diluent, esp. water and/or 1-6C alkanol(s).

Abstract: Adipic acid (I) prodn. involves: (a) hydroformylation of pentenate esters (II) with CO and H2 at elevated temp. and pressure in the presence of Co or Rh carbonyl complexes (III), to give a mixt. (IV) of 5-, 4- and 3-formylvalerate esters; (b) sepn. of the 5-formylvalerate ester (V) from (IV), leaving a mixt. (VI) of 4- and 3-formylvalerate esters; (c) dehydrocarbonylation of (VI) in the presence of gp. VIII element(s) at 50-400 deg. C, to give (II), which are recycled to stage (a); (d) oxidn. of (V) with (gas contg.) O2, to give adipate monoesters (VII); and (e) hydrolysis of (VII) to (I).

Abstract: Prodn. of carbonyl cpds. (I) comprises catalytic isomerisation of allyl alcohol deriv. (II) in presence of a Rh cpd. at 80-180 deg. C. The new features are that (1) reaction is in a tert. phosphine or phosphite; (2) a carrier gas is passed through the reaction mixt. and (3) (I) is sepd. from the withdrawn gas stream by cooling. Specifically, (I) and (II) are of formulae R3R4CH.CHR2.COR1 and R3R4C=CR2-C(OH)HR1 (R1 and R4 = H or Me; or together a 3-6C, aliphatic or olefinic chain; R2 = H, Me or alkoxycarbonyl; R3 = H, Me or CH2OH).

Abstract: In the continuous prodn. of aliphatic cpds. (I) contg. carbalkoxy gps. by reacting olefinically unsatd. aliphatic cpds. (II) with CO and alkanols in the presence of Co carbonyl catalysts (III) and tert. N bases (IV) at 80-200 deg.C and 100-1200 bar, the novelty is that CO is circulated and the CO supplied to the reaction contains 0.1-2.0 vol.% CO2. (IV) has a pKa value of 6-9 and pref. is 3-methylpyridine (IVA) and/or 4-methylpyridine. (II) can be 4-10C alpha-olefins; butadiene; a 4C fraction contg. butadiene; or esters of alkenecarboxylic acids with 4-11C.

Abstract: Alkenecarboxylates of the formula I I where R1 is alkyl of 1 to 6 carbon atoms and n is 2, 3 or 4, are prepared by a process which comprises reacting a lactone of the formula II II where R2 is hydrogen or methyl and m is 1 or 2, with an alkanol of 1 to 6 carbon atoms in the presence of an acidic catalyst at from 150 DEG to 400 DEG C.
