Abstract

PURPOSE: To prevent the decomposition reaction of a lower aliphatic chloro-fluoro- hydrocarbon with an alcoholic OH-containing compound, by the use of t-butylstyrene as a novel reaction retarder.
CONSTITUTION: A mixture of (A) a lower aliphatic chloro-(and/or bromo-) fluoro- hydrocarbon (Freon), e.g. trichlorofluoromethane, dichlorodifluoroethane, etc., and (B) an alcoholic OH-containing compound such as N, N, N', N'-tetrakis-(2-hydroxypropyl)-ethylenediamine, etc., is added with 0.01-5% (based on Freon) of t-butylstyrene, to stabilize the Freon.
EFFECT: The retarder has stronger retarding effect than vinyltoluene, and the mixture can be stored for a long time even at a temperature lower than room temperature.
USE: Aerosol propellant, foaming agent for polyurethane foam manufacturing, etc.
