Abstract
"PROCESSO PARA A ISOMERIZAçãO DE áLCOOIS ALILA". A invenção refere-se ao método para isomerizar álcoois alila extratos a álcoois alila produtos na presença de complexos oxo tungstênio (VI), contendo ligandos que contêm oxigênio adicional em temperaturas entre 50 e 300<198>C. Método citado é caracterizado em que álcoois amino, tais como trietanolamina, dietanolamina, monoetanolamina, tripropanolamina, dipropanolamina, 3-amino-1-propanol, 1-amino-2-propanol, 2-amino-1propanol, butildietanolamina, metildiisopropanolamina, N,N'-bis-(2-hidroxibenzil)-1,2-diaminoetano ou N-(2-hidroxi-benzil)-amina estão contidos no catalisador como ligandos que contêm oxigênio adicional, além das bases de oxigênio conhecidas como ligandos contendo oxigênio adicional ou em lugar dessas bases de oxigênio. O método é particularmente apropriado para produzir álcoois alila produto terciário, tais como linalool, através de isomerização de álcoois alila primário ou secundário tais como geraniol e nerol.
