    摘要： Use is made, for selectively hydrogenating the olefinic double bonds of block copolymers, at least one block of which comprises olefinic double bonds, using a catalyst based on a metal from Group VIII in a medium comprising an organic solvent for the copolymer and an ionic liquid as solvent for the catalyst, of a water-immiscible ionic liquid, preferably an ionic liquid for which the anion is the hexafluorophosphate anion and the cation is the 1-butyl-3-methylimidazolium (bmim+) or 1-ethyl-3-methylimidazolium (emim+) cation.Applied to poly(styrene)-b-poly(butadiene)-b-poly(methyl methacrylate) block copolymers, the poly(butadiene) block of which predominantly possesses a 1,4-microstructure, this process results in copolymers for which the degree of hydrogenation is at least equal to 50% and which exhibit a melting point of greater than 30 °C.

    摘要： The present invention relates to a continuous process for the fluorination of perchloroethylene (PER) in the gas phase in a single stage with hydrofluoric acid (HF) in the presence of a catalyst to give, as major product, pentafluoroethane. The process is characterized in that it is carried out at a temperature of between 280 and 430° C. and with an HF/PER molar ratio of greater than or equal to 20.

    摘要： The invention relates to a method for cooling or heating a fluid or a body by means of a vapour compression circuit containing a heat transfer fluid, said circuit being at least partially contained in an enclosure, and the relative humidity of the air in the enclosure being less than or equal to a threshold value H1 which is less than 50%, the flammability of the heat transfer fluid at relative humidity H1 being less than the flammability of the heat transfer fluid at 50% relative humidity.The invention also relates to a cooling or heating installation suited to the implementation of this method. The invention also relates to a method of protection against the risks of fire or explosion in an enclosure containing at least partially a vapour compression circuit containing a heat transfer fluid, as well as a method for reducing the GWP of a transfer fluid. The invention also relates to heat transfer fluids suited to the implementation of the above methods.
