Abstract: A compound consisting of a linear saturated C8-C24 hydrocarbon-based chain bearing at each end a nitrogen-containing functional group, other than —NH2, is used for the storage of thermal energy. A process for the storage and optionally for the release of thermal energy comprises the contacting of a wall to be cooled with a first heat transfer fluid then of said first heat transfer fluid with a material comprising said compound and optionally the contacting of said material with a second heat transfer fluid then of said second heat transfer fluid with a wall to be heated.

Abstract: Heat exchange fluids comprising an aqueous or aqueous-organic dispersion are disclosed. The dispersions have a purely or predominantly aqueous continuous liquid phase, and at least one dispersed phase comprising particles of at least one polymer. Systems for exchanging or storing heat using the heat exchange fluid are also disclosed.

Abstract: The present invention relates to the use of a compound consisting of a linear saturated C8-C24 hydrocarbon-based chain bearing at each end a nitrogen-containing functional group, other than —NH2, for the storage of thermal energy. It also relates to a process for the storage and optionally for the release of thermal energy, comprising the contacting of a wall to be cooled with a first heat transfer fluid then of said first heat transfer fluid with a material comprising said compound and optionally the contacting of said material with a second heat transfer fluid then of said second heat transfer fluid with a wall to be heated.

Abstract: The present invention relates to a stable aqueous solution (A) comprising an azo dye, a borate buffer and one or more masking agents, wherein the azo dye changes its coloration or coloration intensity in the presence of chlorine dioxide. The present invention further relates to a process for manufacturing the aqueous azo-dye solution (A), and to its use for the determination of residual chlorine dioxide in water.
