The production of solvents for applications such as heat transfer, cleaning, and degreasing, for example. In particular, the production of solvents derived from 1-chloro-3,3,3-trifluoro-propene, such as chloro and/or fluoro substituted alkanes and chloro and/or fluoro substituted trifluoropropenyl ethers.
A process for the transvinylation of a vinyl derivative of a Bronsted acid with a different Bronsted acid which comprises providing a liquid phase mixture containing said vinyl derivative and said Bronsted acid in the presence of a ruthenium compound at a temperature at which transvinylation occurs and recovering as a product of transvinylation the vinyl derivative of the different Bronsted acid. The process is most favorably employed using carboxylic acids to make vinyl esters of carboxylic acids.
