Abstract

The invention discloses a composition with 1,1,1,3,3-pentafluoride butane, which comprises the following parts: a) 51%-95% 1,1,1,3,3-pentafluoride butane, b) 1%-46% non-combustible fluorine compound of perfluoroiodo paraffin and / or perfluorketone. The composition reduces the flammability of 1,1,1,3,3-pentafluoride butane, which is fit for cryogen, foamer, abluent and solvent.

Description

technical field [0001] The present invention relates to a composition containing 1,1,1,3,3-pentafluorobutane and its use, especially as heat transfer fluid, refrigerant, foaming agent, cleaning agent and solvent. Background technique [0002] As we all know, in order to protect the environment on which human beings live, the Montreal Protocol and the Kyoto Protocol have been formulated for the use of fluorine-containing substances as refrigerants, foaming agents, cleaning agents, and solvents. Ozone-destroying HCFCs and HCFCs, and the latter are limiting greenhouse gases. The worldwide implementation of these two international treaties requires the replacement of HCFCs and HCFCs used as heat transfer fluids, refrigerants, blowing and cleaning agents, and solvents. [0003] 1,1,1,3,3-Pentafluorobutane is a good substitute for HCFCs and HCFCs; however, due to its certain flammability, it brings great difficulties to its scope of use. Big restrictions. Some compositions cont...
