PURPOSE:To keep the title compound in stable state over a long period under various kinds of conditions by blending dichlorotrifluoroethane as a foaming agent for production of polyurethane foam with a specific stabilizing agent. CONSTITUTION:When dichlorotrifluoroethane is used as a foaming agent for production of polyurethane foam, dichlorotrifluoroethane is blended with (A) nitrobenzene and (B) a compound selected from myrcene, isobutylene oxide, isopropenyltoluene and 2,6-di-tert.-butylcrezole so as to contain 0.2-2 pts.wt. total amount of 0.1-1 pts.wt. of the component A and 0.1-1 pts.wt. of the component B, based on 100 pts.wt. dichlorotrifluoroethane to suppress the decomposition of a foaming agent for production of polyurethane foam. |
