Application of organic amine additive in synthesis of fluorescent dye intermediate through olefin hydroformylation reaction

The invention discloses application of an organic amine additive in synthesis of a fluorescent dye intermediate through olefin hydroformylation reaction, and the application comprises the following steps: S1, the structure of the additive involved in the patent takes a nitrogen atom as a center, and three substituent groups linked with the nitrogen atom are alkyl groups or aromatic groups; and S2, in the hydroformylation reaction process, very few additives are introduced into the reaction system. The activity of a rhodium-aryl phosphine catalyst and the chemical selectivity of a product aldehyde can be obviously improved by using proper types and quantity of additives. The organic amine additive has the characteristics that compared with other types of additives reported in the literature, the organic amine additive can better regulate and control the activity of a rhodium-aryl phosphine catalyst and greatly improve the chemical selectivity of the product aldehyde, the organic amine additive provided by the invention can overcome the defects of other types of additives reported in the literature, and the cost of hydroformylation industrial production of various olefins is reduced.

Aqueous phase hydrogenation of furfural to tetrahydrofurfuryl alcohol over Pd/UiO-66

A Pd/UiO-66 catalyst was synthesized with well-dispersed Pd nanoparticles. The obtained catalyst was tested in the hydrogenation of furfural to tetrahydrofurfuryl alcohol in various solvents, Water was found to be the most suitable solvent. Pd/UiO-66 exhibited much higher activity than Pd/SiO2 and Pd/γ-Al2O3, completely converting furfural to tetrahydrofurfuryl alcohol with 100% selectivity under mild conditions. The hydrogenation of C[dbnd]O moiety in tetrahydrofurfural was rate-determining step. Static adsorption measurement indicated that the adsorption of furfural on UiO-66 was significantly stronger than that on SiO2 or γ-Al2O3, suggesting that the adsorption play an important role in the gas-liquid-solid furfural hydrogenation reaction.
