Process for the preparation of a reaction medium, reaction medium and use of a reaction medium

摘要

A process for producing a reaction medium (100), comprising: - providing a powdery base material (104) which reacts with heat and / or heat release chemically and / or physically reversibly with a reactant material (124); Coating at least a portion of a surface (110) of particles (106) of the powdery base material (104) with a powdered coating material (114) capable of reacting with the reactant material (124), with indirect incorporation of reactant material (124) the pulverulent base material (104) can be obtained by initially receiving the reactant material (124) by means of the coating substance (114) and then passing it on to the powdery base material (104), wherein the coating material (114) is added to the powdery base material (104) in an amount which exceeds the amount necessary for complete coating of the surface (110) of the particles (106) of the pulverulent base substance (104), and wherein the surface (110) of the particles (106) of the pulverulent base material (104) is mixed with agglomerates (116 ) is coated from particles (112) of the coating material (114).
