  • Patent number: 6632330
    Abstract: A process for the recovery of substantially pure alkyl alkanoate, such as ethyl acetate, from an impure feedstock. The impure feedstock is contacted with a selective hydrogenation catalyst in the presence of hydrogen in a selective hydrogenation zone maintained under selective hydrogenation conditions effective for selective hydrogenation of impurities containing reactive carbonyl groups thereby to hydrogenate the impurities to the corresponding alcohols. After recovery from the selective hydrogenation zone of a selectively hydrogenated reaction product mixture including the alkyl alkanoate and the corresponding alcohols, this is distilled in one or more distillation zones so as to produce substantially pure alkyl alkanoate therefrom which is recovered.

  • Patent number: 4765869
    Abstract: A continuous process is described for the production of a substantially acid free dialkyl maleate, for example diethyl maleate, from a feed stream containing a major amount of dialkyl maleate and a minor amount of the corresponding monoalkyl maleate. This comprises continuously distilling the feed stream in a primary distillation zone, which can comprise a single distillation column or a series of distillation columns connected in series, so as to give (i) a bottom fraction containing monoalkyl maleate and dialkyl maleate in admixture, (ii) a vaporous fraction comprising alkanol, and (iii) an intermediate fraction that is substantially free from alkanol and comprises a major proportion of diethyl maleate and a minor proportion of maleic anhydride. The intermediate fraction (iii) is redistilled in a secondary distillation zone to yield (i) an overhead fraction containing maleic anhydride and (ii) a bottom fraction containing substantially acid free dialkyl maleate.

  • Patent number: 4751334
    Abstract: Butane-1,4-diol is produced by vapor phase hydrogenolysis of an alkyl ester of a C.sub.4 dicarboxylic acid, e.g. diethyl maleate, over a reduced Cu-Cr or Cu-Zn mixed oxide catalyst. Two adiabatic hydrogenolysis zones are used. The mixture exiting the first of these zones is cooled (by, for example, 5.degree. C.) and the resulting cooled mixture is fed to the second zone in which is reequilibriates at a lower temperature to increase the butane-1,4-diol yield at the expense of gamma-butyrolactone. Typical reaction conditions include use of temperatures of 150.degree. C. to 200.degree. C., pressures of 25 to 70 bar, and a H.sub.2 :ester molar ratio of 100:1 to 800:1. When using a maleate ester it is often advantageous to hydrogenate this to the corresponding succinate ester in an upstream hydrogenation zone prior to entry to the first hyrogenolysis zone.

  • Patent number: 4391677
    Abstract: A process is disclosed for producing a substantially sulphur-free, butene-1 rich stream from a butene-containing C.sub.4 hydrocarbon feed stream by passage through a desulphurization zone, e.g. successive beds of active alumina and zinc oxide, and then distilling it. The desulphurization zone adsorbs, absorbs or converts to higher boiling sulphurous compounds low boiling sulphurous impurities such as H.sub.2 S, COS and CH.sub.3 SH. A sulphur-free butene-1 rich stream is recovered overhead from the distillation zone, while a butene-2 rich stream containing higher boiling sulphurous impurities originally present or produced in the desulphurization zone is recovered as a bottom product. A dechlorination zone (containing, for example, a charge of copper impregnated active carbon) can be provided upstream or downstream from the desulphurization zone but upstream from the distillation zone or can be provided in the path of the butene-1 rich stream from the distillation zone.
