Abstract

"PROCESSO MELHORADO PARA A SìNTESE DE áLCOOIS INSATURADOS". A presente invenção refere-se a um processo de preparação de um álcool insaturado (álcool olefínico), tal como, um monoálcool homoalílico ou poliol homoalílico, que envolve a proteção de um ácido graxo ou éster de ácido graxo insaturado substituído por hidróxi, tal como ricinoleato de metila, derivado de um óleo de sementes, para formar um ácido graxo ou éster de ácido graxo insaturado protegido por hidróxi; homometatessizar ou metatessização cruzada do ácido graxo ou éster de ácido graxo insaturado protegido por hidróxi para produzir uma mistura de produto contendo um produto de metátese insaturado protegido por hidróxi; e desproteger o produto de metátese insaturado protegido por hidróxi sob condições suficientes para preparar o álcool insaturado. Preferivelmente, o ricinoleato de metila é convertido por metátese cruzada ou homometátese no monoálcool mono-alílico 1-deceno-4-ol ou o poliol homoalílico 9-octadeceno-7,12-diol, respectivamente.
