Abstract
PURPOSE:To enable use of a lower aliphatic halogenated hydrocarbon containing fluorine, another halogen and hydrogen as a foaming agent, aerosol and solvent, by adding an epoxy compound to the hydrocarbon so that the hydrocarbon is stabilized to alcoholic OH group. CONSTITUTION:A lower aliphatic halogenated hydrocarbon containing fluorine, another halogen and hydrogen (hydrogen-containing flon) (e.g. 1,1-dichloro-2,2,2- trifluoroethane) is incorporated with 0.05-2.0wt.% epoxy compound so that the hydrogen-containing flon is stabilized to alcoholic OH group. By the stabilization, the use of the hydrogen-containing flon as a foaming agent, aerosol and solvent wherein the hydrogen-containing flon is used in a state of coexistence of alcoholic OH group is made possible. The hydrogen-containing flon is effective especially for shelf stability of polyol containing a hydrogen-containing flon as a foaming agent. Mono- and diepoxides are preferable as the epoxy compound.
