摘要:
The concentration of hydrogen sulfide in a hydrocarbon can be mitigated by intruding therein a zinc carboxylate oxo complex composition prepared by reacting particulate zinc oxide with a mixture of two or more carboxylic acids wherein the zinc carboxylate oxo complex composition is soluble in hydrocarbons. Useful acids useful include acetic acid, oleic acid, isobutyric acid, lineoleic acid, cekanoic acid, and neodecanoic acid.
摘要:
A process for the separation of internal olefins from a mixed feedstock comprising internal olefins and paraffins, wherein said process comprises: (i) reacting said mixed feedstock with a trialkylaluminium compound in the presence of an isomerisation/displacement catalyst in order to cause isomerisation of the internal olefins and to displace alkyl group(s) from said trialkylaluminium compound to form an alkylaluminium compound wherein at least one of the alkyl groups bound to the aluminium is an alkyl group which has been derived from the isomerisation of said internal olefins; and (ii) reacting the alkylaluminium compound formed in step (i) with one or more displacement olefins in the presence of an isomerisation/displacement catalyst in order to cause the displacement olefins to optionally isomerise and to displace alkyl group(s) from the alkylaluminium compound to form a trialkylaluminium compound and to liberate the 1-olefins derived from the internal olefins of the mixed feedstock, which 1-olefins are isomerised to form internal olefins.
摘要:
A process for producing an aromatic compound which can effectively decrease the contents of halogen elements in the aromatic compound and an aromatic compound which is produced in accordance with the process and useful as the material for obtaining an organic electroluminescence device having a long life are provided. The process for producing an aromatic compound comprises bringing an aromatic compound which is produced via an intermediate compound having halogen elements and has contents of halogen elements of 10 to 1,000 ppm by mass into reaction with a dehalogenating agent to decrease the contents of halogen elements to 10 ppm by mass or smaller, and an aromatic compound which is produced in accordance with the process.
摘要:
Gegenstand der Erfindung ist ein Verfahren zur Abtrennung von 1-Buten aus C 4 -haltigen Kohlenwasserstoffgemischen, enthaltend Isobuten und 1-Buten, durch Hydroformylierung, wobei das verwendete Katalysatorsystem aus einem der Übergangsmetalle der Gruppen 8 bis 10, bevorzugt Rhodium, und einem Bisphosphitliganden der folgenden Formeln Ia bis Ic
besteht, wobei der Bisphosphitligand der oben angegebenen Formel I in einem Überschuss eines molaren Verhältnis von 100 : 1 bis 1 : 1 zum Ubergangsmetall eingesetzt wird, und dass bei einem 1-Butenumsatz von über 95 % weniger als 5 % des vorliegenden Isobutens umgesetzt werden.

摘要:
Supported organometallic compounds of Groups II, III and IV of the Periodic Table are utilized for purifying fluids particularly hydrocarbon fluids, noble gases, nitrogen and hydrogen and desirable hydrocarbon solvents and olefins to remove impurities such as oxygen, sulfur, halogen-containing compounds, active hydrogen compounds and other polar compounds. The supported organometallic compounds preferably supported metal alkyls, are prepared by reacting the pretreated dried solid support material with the organometallic compounds in such a manner as to effect loading or impregnation of the organometallic moieties onto the support.
