Effect of the spacer chain length on the critical micelle concentration and micelle ionization degree. Langmuir — These spectra are consistent with the structure of formyl stearyl alcohols. Formyl proton of the product has two groups of chemical shift with multiplet. The analysis showed that this product was mixture of formyl stearyl alcohol bearing formyl moiety at the end of long chain and those bearing formyl moiety among the long chain. Ratio of intensities of the two formyl protons was 0.
This means that internal double bond of oleyl alcohol was transferred to the end of the long chain by isomerization during the hydroformylation. Accordingly it was reasonable that the catalyst showed good activity in the isomerization of the oleyl alcohol. Yield of formyl stearyl alcohol was At above this temperature, decrease of yield was observed.
It may be owe to the decomposition of the catalyst. In addition, higher temperature promoted the competitive hydrogenation of oleyl alcohol, which can be regard as one of the reasons for the decrease of selectivity of the reaction.
Multicomponent Reactions Accelerated by Aqueous Micelles
Meanwhile from Fig. From Fig. The results indicated that the catalyst was recoverable. Yield of aldehyde decreased in the fourth run. The in situ formed catalyst was easily separated from the reaction mixture and Fig. References  M. Beller, B.
