It is an object to provide a heat storage medium capable of maintaining the latent heat capacity even if a supercooling inhibitor is added. A heat storage medium according to an aspect of the present invention is a heat storage medium which undergoes a phase change at a predetermined temperature and contains water, a main agent made of a quaternary ammonium salt forming a semi-clathrate hydrate, a pH adjustor maintaining alkalinity, and a nucleating agent generating cations exhibiting positive hydration. The heat storage medium separates into a first liquid layer containing the main agent and a second liquid layer containing the nucleating agent in an environment with a temperature exceeding the phase change temperature.

A halide compound having one or more carbon-carbon unsaturated bonds is catalytically reduced with substantially no dehalogenation to produce a reduced halide compound in which at least one of the one or more unsaturated bonds is reduced. Specifically provided is a method for producing a reduced halide compound including steps of: reacting a nickel compound, a zinc compound, and a borohydride compound in a solvent to obtain a reduction catalyst; and subjecting a halide compound having one or more carbon-carbon unsaturated bonds to catalytic reduction in the presence of the reduction catalyst to reduce at least one of the one or more carbon-carbon unsaturated bonds to thereby obtain a reduced halide compound.

The present disclosure relates to a process for the halogenation of hydrocarbon. In accordance with the process of the present disclosure a hydrocarbon and a halogen is introduced in a reaction vessel. Light having wavelength in the range of 390 to 780 nm is then passed into the reaction vessel for a time period of 2 to 12 hrs. to obtain a halogenated hydrocarbon. The hydrocarbon is agitated before or after the introduction of the halogen in to the reaction vessel.

A method includes brominating a butanes feed stream including i-butane in a bromination reactor to form a bromination effluent stream including t-butyl bromide. The method includes dehydrobrominating the t-butyl bromide to form isobutylene. Another method includes brominating a mixed pentanes feed stream including i-pentane and n-pentane in a bromination reactor to form a bromination effluent stream including t-pentyl bromide. The method includes dehydrobrominating the t-pentyl bromide to form isoamylene and HBr.
