General Description

2-Ethylvaleraldehyde, also known as 2-ethylpentan-3-one, is an organic compound with the chemical formula C7H14O. It is a colorless liquid with a strong, pungent odor that is commonly used as a flavoring agent in the food industry. It is also used in the production of perfumes and as a chemical intermediate in the synthesis of other compounds. 2-Ethylvaleraldehyde is derived from valeraldehyde, a five-carbon aldehyde, by the addition of an ethyl group to the carbon chain. It is a highly flammable liquid and should be handled with care. In addition to its use in the food and fragrance industries, 2-ethylvaleraldehyde is also used as a solvent in the printing and dyeing industries.

Method for preparing aldehyde through hydroformylation of internal olefin

The invention provides a method for preparing aldehyde through hydroformylation of internal olefin. The preparation method is characterized by comprising the following steps: adding a water-soluble rhodium compound, a water-soluble diphosphine ligand, an additive, deionized water and internal olefin into a reaction kettle equipped with a stirrer and a thermocouple; carrying out replacing 3-5 timesby using synthesis gas formed by mixing hydrogen and carbon monoxide according to a volume ratio of 1: 1; carrying out pressurizing to 1.0-5.0 MPa; conducting a reaction for 2-10 hours at a temperature of 60-120 DEG C; and conducting cooling, taking out a reaction product, and performing separating to obtain the product aldehyde.

Enhancing catalytic performance of activated carbon supported Rh catalyst on heterogeneous hydroformylation of 1-hexene via introducing surface oxygen-containing groups

Activated carbon supported rhodium (Rh/AC) catalysts with different amounts of oxygen-containing functional groups were prepared by nitric acid (HNO3) treatment at varied temperatures. Thermal analyses of Rh/AC catalysts with or without this acidic treatment were characterized by thermogravimetric analysis (TGA) and temperature programmed desorption (TPD). The change of surface oxygen-containing functional groups was characterized by Fourier transform infrared spectrometry (FTIR) and X-ray photoelectron spectroscopy (XPS). These characterization results indicated that the amount of oxygen-containing functional groups increased with the treatment temperature. The influence of these oxygen-containing functional groups on the products selectivities in heterogeneous hydroformylation reaction was investigated in detail. These abundant functional groups were benefited to improve the selectivity of n-heptanal, resulting in higher n/i (normal to iso) ratio of heptanal. The Rh/AC catalyst being treated at 80?°C had the highest n/i ratio of 2.3, due to the maximum amount of oxygen-containing functional groups, which was almost double to that of raw Rh/AC catalyst. Moreover, abundant functional groups on catalyst suppressed hydrogenation of hexene, decreasing the selectivity of hexane from 4.9% of raw Rh/AC to 0.2%. These findings disclosed that these oxygen-containing functional groups on catalysts played an extremely important role in improving the catalytic performance of heterogeneous hydroformylation reaction, providing a new viewpoint for the studies on heterogeneous hydroformylation.

On rhodium complexes bearing H-spirophosphorane derived ligands: Synthesis, structural and catalytic properties

We investigated the coordination properties of H-spirophosphoranes towards rhodium ion. Symmetrical phosphorus ligands: HP(OCH2CH 2NH)2 L1, HP(OCH2CM-2NH)2 L2, HP(OCMe2CMe 2O)2 L3, HP(OC6H4NH)2 L4, and unsymmetrical phosphorus ligands: HP(OCMe2CMe2O)(OCH2CM-2NH) L5, HP(OCMe2CMe2O)(OC6H4NH) L6 were found to coordinate to rhodium precursor [Rh(CO)2Cl]2 exclusively in protonated k2-P,E (E =N, O) bidentate fashion, yielding complexes [Rh(CO)ClL] 1-6. The complexes were characterised by spectroscopic methods. The molecular structures of the ligand L6 complexes 3, 5 and 6 were determined by single-crystal X-ray diffraction. The catalytic activity of the complexes was determined in hydroformylation reaction of 1-hexene. Complexes 1 and 2 appeared to be active in isomerisation reactions yielding 76 and 62% of 2-hexene. When used with six-fold excess of triphenylphosphite P(OPh)3 as a modified ligand, the most active catalyst 1 in hydroformylation reaction produced 66% of aldehydes and 22% of 2-hexene.
