FREMGANGSMAATE TIL FREMSTILLING AV B-FENYLETYLALKOHOL OG B-FENYLETYLACETAT

摘要

Mixtures of B-phenylethyl alcohol and B-phenylethyl acetate are prepared by homologation of mixtures containing benzyl alcohol, benzaldehyde benzyl acetate, and dibenzyl ethers in the presece of a cobalt catalyst. The feedstock may be obtained by acetoxylation of toluene followed by hydrolysis, or alternatively, by oxidation of toluene to benzaldehyde followed by reduction to benzyl alcohol. Components in the reactor effluent, e.g., dibenzyl ethers, may be recycled to suppress by-product formation and increase the overall yield of the process.
