The present invention relates, in part, to the discovery that, during the fluorination of certain fluoroolefin starting reagents, oligomerization/polymerization of such reagents reduces the conversion process and leads to increased catalyst deactivation. The present invention also illustrates that vaporizing such starting reagents in the presence of one or more organic co-feed reduces such oligomerization/polymerization and improves catalytic stability.

Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of washing the bound zeolite base in the presence of an alkali metal, prior to impregnating the bound zeolitic support with the transition metal. Alkali metals such as potassium and cesium may be used.

A method for producing anhydrosugar alcohol according to the present invention can increase the yield of anhydrosugar alcohol even in the absence of a catalyst or in the presence of a small amount of a transition metal salt catalyst by controlling the temperature of a high-temperature reaction, which converts sugar alcohol to anhydrosugar alcohol, in two steps, that is, a first low-temperature reaction step and a second high-temperature reaction step.
