Abstract
PURPOSE: To inhibit the reaction of a lower aliphatic fluorinated chlorinated hydrocarbon (flon) with alcoholic hydroxyl groups even under severe conditions and to prevent the flon from considerable coloring and lowering of pH, by adding an isopropenylxylene as a stabilizer to the flon.
CONSTITUTION: The addition of isopropenylxylene can stabilize a flon to alcoholic hydroxyl groups. As the isopropenylxylene, p-isopropenyl-o-xylene or p-isopropenyl- m-xylene is readily available and preferably used. As the flon, esp. 1W2 C fluorinated chlorinated alkanes are preferred. The stabilizer is highly effective for e.g. trichlorofluoromethane which is esp. unstable to alcoholic hydroxyl groups, and is also effective when used for the expansion of urethane containing an amine polyol using a flon as a blowing agent. The amount of the stabilizer to be added is preferably 0.05W5.0wt.% based on the flon
