METHOD OF INHIBITING DECOMPOSITION OF 1,1,1,2,3,3-HEXAFLUOROPROPANE AND 1,1,1,3,3-PENTAFLUOROPROPANE AND DECOMPOSITION INHIBITOR |
摘要 |
(1) At least one nitro compound and (2) at least one member selected from the group consisting of an aromatic hydrocarbon and an alicyclic unsaturated hydrocarbon are added to 1,1,1,2,3,3-hexafluoropropane (HFC236ea) or 1,1,1,3,3-pentafluoropropane (HFC245fa). Optionally, (3) at least one member selected from the group consisting of an aliphatic unsaturated hydrocarbon, an epoxy compound, an ether compound, a phenol compound, an ester compound and a cyclic compound is further added. As a result, HFC236ea and HFC245fa have remarkably improved stability at any stages and in any states during storage and use of HFC236ea or HFC245fa and during use of the foamed product. |
