Title:
アリルアルコールの異性化の方法
Document Type and Number:
Japanese Patent JP4477276
Kind Code:
B2
Abstract:
Process for the isomerization of precursor allyl alcohols to product allyl alcohols in the presence of tungsten oxo(VI) complexes comprising additional nitrogen-containing ligands at temperatures of from 50 to 300° C., wherein, in the catalyst, as well as the nitrogen bases known as additional nitrogen-containing ligands, or instead of these nitrogen bases, aminoalcohols such as triethanolamine, diethanolamine, monoethanolamine, tripropanolamine, dipropanolamine, 3-amino-1-propanol, 1-amino-2-propanol, 2-amino-1-propanol, butyldiethanolamine, methyldiisopropanolamine, N,N'-bis(2-hydroxybenzyl)-1,2-diaminoethane or N-(2-hydroxybenzyl)amine are present as additional nitrogen-containing ligands. The process is particularly suitable for the preparation of tertiary product allyl alcohols, such as linalool, by isomerizing primary or secondary allyl alcohols, such as geraniol and nerol.
