6.9%Chromat.; 22.6%Chromat.; 16.5%Chromat.; 6.1%Chromat. | The reactor tube was filled with 8.9 g of copper zinc oxide catalyst (Unicat MTS401) and the catalyst was reduced in 95:5 N2/hydrogen stream at 0.2 liters/min at a temperature of 160 C for 18 h. The N2/hydrogen mixture was replaced by a hydrogen line and reduction was continued for another hour at 0.4 liters/min at 200 C. Then the reactor pressure was set to 300 psi hydrogen with temperature at 183 C and hydrogen flow at 400 cc/min. The HPLC pump was turned on and the Mixture A (from the methyl ketene reaction above) was pumped into the reactor at rate of 0.05 ml/min. After 30 min hydrogen flow rate was increased to 660 cc/min and temperature of the reactor to 211 C and the liquid samples were collected. GCMS analysis for product taken over duration of reaction indicated formation of 2- methylpentanol, 3-pentanol, pentanone, as two major products of the hydrogenation along with 3-pentanone (6%) and other higher alcohols presented in smaller amounts. GCMS qualitative analysis of higher alcohols formed is shown in Table 31. 100% of the methyl ketene dimer/trimer mixture was reduced. 43-50% higher alcohol product was formed of which 16-27% was 3- pentanola and 19-28% was 2-methyl pentanol. |

With [C6H3-2,6-(OP(tBu)2)2]IrH2; trifluorormethanesulfonic acid; hydrogen In 1,4-dioxane at 125℃; Autoclave; | 11 Hydrogenation of 1,2 Propanediol. Reactions containing no water and/or more than 0.25 equivalents of triflic acid gave poor selectivity toward the n-alcohol and yielded up to fifteen distinct products which were identified by 1H NMR spectroscopy and/or GC/MS. Several of these products along with pathways that have been proposed for their generation are shown in Scheme 1. In addition to compounds shown in Scheme 1, dipropylene glycol, dipropyl ether, and isopropyl ether were also identified and reasonably result from condensation of the respective alcohols. In addition, some decomposition of the dioxane solvent was observed leading to the generation of ethanol and ethylene glycol, which were not observed in the absence of dioxane. With the exception of propane, isomers of 2,5- and 2,6-dimethyldioxane, and dipropoxypropane, which were observed by NMR spectroscopy and/or GC-MS, all major byproducts were quantified using a GC assay method developed and verified with authentic samples. The product profiles obtained under each set of reaction conditions were characterized by NMR spectroscopy, and GC-MS and/or comparison to authentic compounds prepared by independent synthesis. |
