[0053] Hydroformylation of Butene to Valeraldehyde in Toluene
[0054] A 150 ml autoclave was charged with rhodium dicarbonyl acetylacetonate (0.05 mmol), trivalent ferrocene cation bis(diphenyl)phosphine hexafluorophosphonate (0.10 mmol) and the specific amount of accelerator indicated in the table . Add toluene (25mL) and butene (50mmol), then 2 Replacement reactor. with H 2 and CO to pressurize the reactor to 2.0 MPa and heat to 120 °C. The autoclave was stirred and maintained at 120°C for a total of 3 hours. The autoclave is then cooled, excess gas is vented, and the contents are recovered. The contents were analyzed for the presence of n-valeraldehyde and 3-methylbutyraldehyde by internal standard gas chromatography. The results are shown in Table 1 below.

[0062] Hydroformylation of Butene to Valeraldehyde in Toluene
[0063] A 150 ml autoclave was charged with rhodium trichloride (0.05 mmol), ferrocene cation bis(diphenyl)phosphine hexafluorophosphonate (0.10 mmol) and ammonium hexafluorophosphate (0.05 mmol). Add toluene (25mL) and butene (50mmol), then 2 Replacement reactor. with H 2 and CO to pressurize the reactor to 2.0 MPa and heat to 120 °C. The autoclave was stirred and maintained at 120°C for a total of 3 hours. The autoclave is then cooled, excess gas is vented, and the contents are recovered. Analysis of the contents by internal standard gas chromatography revealed that the conversion of butene was 79.5%, and the selectivity to n-valeraldehyde was 91.0%.

[0068] Hydroformylation of Butene to Valeraldehyde in Toluene
[0069] A 150 ml autoclave was charged with rhodium carbonyl acetylacetonate (0.05 mmol), trivalent ferrocene cation bis(diphenyl)phosphine hexafluorophosphate (0.10 mmol) and ammonium hexafluorophosphate (0.05 mmol). Add butene (50mmol), then in N 2 Replacement reactor. with H 2 and CO to pressurize the reactor to 2.0 MPa and heat to 90 °C. The autoclave was stirred and maintained at 90°C for a total of 3 hours. The autoclave is then cooled, excess gas is vented, and the contents are recovered. Analysis of the contents by internal standard gas chromatography revealed that the conversion of butene was 68.8%, and the selectivity to n-valeraldehyde was 91.0%.
