A method includes: providing a mixture including at least one alkyl tosylate and a Grignard reagent; and reacting the at least one alkyl tosylate with the Grignard reagent in a C—C coupling reaction mechanism to form a branched aliphatic alcohol.

Fluoride-containing nickel iron oxyhydroxide electrocatalysts for use as anodes in anion exchange membrane electrolyzers for generating hydrogen gas.

A system for generating hydrogen includes a vessel having a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on the vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached.

The present invention relates, at least in part, to a process for making chlorotrifluoroethylene (CFO-1113) from 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a). In certain aspects, the process includes dehydrochlorinating 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a) in the presence of a catalyst selected from the group consisting of (i) one or more metal halides; (ii) one or more halogenated metal oxides; (iii) one or more zero-valent metals or metal alloys; (iv) combinations thereof.
