Abstract: A process for the manufacture of pent-3-enoic acid and its alkyl esters, of the general formula CH3-CH=CH-CH2-CO-OR where R is hydrogen or alkyl of 1 to 4 carbon atoms, comprising carbonylating butadiene with carbon monoxide and a compound ROH at from 300 to 1,000 bars CO pressure and from 100 DEG to 160 DEG C. in the presence of cobalt catalysts and nitrogen bases, wherein C4 cuts are used as starting materials and a tertiary amine having a pKA of from 3 to 11 is used as the nitrogen base. The pent-3-enoic acid or alkyl esters produced may be used for the manufacture of adipic acid or its alkyl esters, which compounds are starting materials for the manufacture of nylons.

Abstract: Ethanol is produced continuously via the carbonylation of methanol, by (a) carbonylating methanol, in a reactor R, in the presence of a carbonyl complex of a metal of group VIII of the periodic table and of a halogen compound, (b) separating, in a distillation column D1, the reactor discharge, into a top fraction comprising methyl acetate, methanol, dimethyl ether and an organohalogen compound, and into a bottom fraction comprising water, small quantities of acetic acid and the catalyst, if the latter is not in a fixed bed, the residence time being so adjusted that the greater part of the acetic acid reacts with the methanol present to give methyl acetate, (c) separating the top fraction from D1, in a distillation column D2, into a top fraction comprising small quantities of methyl acetate, methanol, dimethyl ether and the organo-halogen compound, and a bottom fraction comprising methyl acetate and methanol, and recycling the top fraction to reactor R, (d) distilling off, via the top of distillation column D3, the greater part of the water from the bottom fraction from D1and removing this water from circulation, and recycling to reactor R the bottom fraction consisting of small quantities of water, acetic acid and the catalyst, (e) using hydrogen to hydrogenate, in the hydrogenation reactor H, the bottom fraction from D2, in a conventional manner, to give a mixture of methanol and ethanol, and (f) separating the mixture into ethanol and methanol in a distillation column D4, and recycling the methanol to reactor R.

Abstract: Dimethyl adipate, (I) dimethyl alpha-Me glutarate, (II), and dimethyl Et succinate, (III) are recovered from reaction mixts. prepd. by reacting Me pent-3-enoate with CO, under increased temp. and pressure, in the presence of Co carbonyl, heterocyclic aromatic tert. N bases and MeOH. The reaction mixt. is extd. with paraffinic hydrocarbons having b.pt. 40-120 degrees C in the presence of 0.1-5 wt.% water, w.r.t. reaction mixt. The catalyst-contg. MeOH phase is separated. (I), (II), and (III) are obtd. from paraffinic hydrocarbon phase by distn., e.g. by fractional distn. or several consecutive distns. (I), (II) and (III) mixts. with water glass can be used as oil reinforcing agents. (I) is easily converted to adiponitrile, which can be hydrogenated to hexamethylene diamine, a starting material for high polymers. (I) (II) and (III) are obtd. in pure form and the catalyst is not decomposed and can be recovered in active form. The catalyst-contg. aq. MeOH phase can be re-used for methoxy-carbonylation of Me pent-3-enoate. The recovered paraffinic hydrocarbons can be re-used for extn.

Abstract: The isolation and regeneration of catalysts of type I or II ClRh(CO)(PR3)2I HRh(CO)(PR3)3II, where the R's are identical or different hydrocarbon radicals, to give the catalysts in a pure form, is effected by regenerating aqueous rhodium salt solutions, as obtained on treating distillation residues of hydroformylation mixtures with oxygen-containing mineral acids and peroxides, by a method wherein the said aqueous rhodium salt solutions are treated with a cation exchanger, the latter is then separated from the solution, the absorbed rhodium ions are desorbed with hydrochloric acid, the hexachlororhodate solutions, containing hydrochloric acid, are reacted, in the presence of a water-soluble organic solvent and a tertiary phosphine PR3, with carbon monoxide, or with compounds which eliminate carbon monoxide, at from 0 DEG to 150 DEG C and from 1 to 5 bars, and the resulting complexes I or, if the process is carried out under hydrogenating conditions, the resulting complexes II, are separated off.
