Abstract
The invention provides an improved process for the preparation of a vinyl derivative of a Bronsted acid, wherein a vinyl derivative of a first Bronsted acid is subjected to transvinylation by reactive distillation with a second Bronsted acid.
Claims16
A transvinylation process which comprises reacting a vinyl derivative of a first Bronsted acid with a second Bronsted acid, in a reaction vessel containing a transvinylation catalyst, to form a conjugate acid of said vinyl derivative reactant and a vinyl derivative product of said second bronsted acid which is less than volatile than said vinyl derivative reactant, said transvinylation reaction being carried out under conditions whereby unreacted vinyl derivative of said first Bronsted acid is volatilized and serves as a stripping agent for removing less volatile product of reaction from the reaction vessel as the reaction progresses.
A transvinylation process which comprises feeding into a reaction vessel, equipped with a distillation column, a vinyl derivative of a first Bronsted acid, a second Bronsted acid and a transvinylation catalyst, reacting the resultant mixture to form a conjugate acid of said vinyl derivative reactant and a vinyl derivative product of said second Bronsted acid which is less volatile than said vinyl derivative reactant, said transvinylation reaction being carried out under conditions whereby the unreacted vinyl derivative of said first Bronsted acid is volatilized and serves as a stripping agent for removing a less volatile product of reaction from the reaction vessel into said distillation column as the reaction progresses and recovering distilled product.
