InactiveCN110981692ALow purityHigh purityOrganic compound preparationHydrocarbon by hydrogenationAlkaneIsononyl alcohol
The invention discloses a method and a system for coproducing isononyl alcohol and C8 alkane. The method comprises the following steps: in a H2 / CO mixed atmosphere, carrying out carbonylation / hydrogenation reaction on a mixed reaction system containing C8 olefin and a cobalt phosphine catalyst at 150-210 DEG C under the pressure of 5-11 Mpa to obtain a crude isononyl alcohol product and C8 alkane;and carrying out hydrogenation reaction on a hydrogenation reaction system containing the crude isononyl alcohol product and a hydrogenation catalyst at 60-190 DEG C under the hydrogenation pressureof 1-9 Mpa to obtain isononyl alcohol. The invention provides the method for coupling hydroformylation reaction and hydrogenation reaction. A cheap and efficient coupling catalyst is developed, through reasonable design of a reaction separation system, a heterogeneous system is well mixed and efficient in reaction, C8 olefin is finally converted into C8 alkane and isononyl alcohol, and high-quality gasoline components and high-end plasticizer raw materials can be produced at the same time.

ActiveCN105461561AImprove oxidation capacityImprove conversion rateOrganic compound preparationOrganic-compounds/hydrides/coordination-complexes catalystsIsononyl alcoholActivated carbon
The invention provides a triisononyl citrate compound and a preparation method thereof; the preparation method comprises preparation of a loaded heteropoly acid catalyst and preparation of triisononyl citrate; the invention belongs to the citric acid plasticizer field. The preparation method comprises the steps: esterifying citric acid and isononyl alcohol under the action of a catalyst at the temperature of 110-170 DEG C to synthesize triisononyl citrate with the reaction time of 1-3 hours, during reaction, taking cyclohexane as a water carrying agent, after the completion of the reaction, cooling the solution to 50-80 DEG C, filtering to obtain the catalyst, recycling and reusing, and carrying out reduced pressure dealcoholization, alkali washing and water washing to be neutral; and adding activated carbon, carrying out adsorption decolorization, drying, and thus obtaining the product triisononyl citrate. The catalyst used in the method has high catalytic activity and high repeated utilization rate, the purity of the obtained product is high, and the shortcomings that a conventional citric acid low-carbon alcohol ester plasticizer has high volatility, poor low-temperature resistance, poor extraction resistance and the like are overcome.
