A METHOD FOR AEROSOLIZING A LIQUID WHICH UNDERGOES A DELETERIOUS CHEMICAL CHANGE WHEN RAISED TO AN ELEVATED DECOMPOSITION TEMPERATURE BELOW ITS VAPORIZATION TEMPERATURE FOR AN APPRECIABLE PERIOD OF TIME, SAID LIQUID BEING ONE WHOSE SURFACE TENSION AND VISCOSITY ARE SUCH AT A TEMPERATURE ABOVE ITS DECOMPOSITION TEMPERATURE AND BELOW IS VAPORIZATION TEMPERATURE AS TO PERMIT IT TO BE AEROSOLIZED, WHICH METHOD COMPRISES HEATING AN INERT GAS TO AN ELEVATED TEMPERATURE ABOVE THE DECOMPOSITION TEMPERATURE AT WHICH THE LIQUID UNDERGOES SUCH DELETERIOUS CHEMICAL CHANGE, CONTACTING A RAPIDLY MOVING STREAM OF SAID HEATED GAS AT SAID ELEVATED TEMPERATURE WITH A STREAM OF SAID LIQUID, SAID STREAM OF LIQUID BEING BELOW ITS DECOMPOSITION TEMPERATURE, SAID CONTACT AEROSOLIZING AT LEAST AN APPRECIABLE PORTION OF SAID LIQUID, THE TIME DURATION OF SUCH CONTACT BETWEEN SAID LIQUID AND SAID GAS BEING INSUFFICIENT TO EFFECT ANY DELETERIOUS CHEMICAL CHANGE ON SAID LIQUID BUT BEING SUFFICIENT TO RAISE THE TEMPERATURE OF SAID LIQUID FOR A SHORT TIME PERIOD ABOVE SUCH DECOMPOSITION TEMPERATURE AT WHICH SAID LIQUID UNDERGOES A DELETERIOUS CHEMICAL CHANGE TO A TEMPERATURE BELOW THE LIQUID''S VAPORIZATION TEMPERATURE AT WHICH TEMPERATURE THE SURFACE TENSION AND VISCOSITY OF THE LIQUID ARE REDUCED TO A LEVEL PERMITING THE LIQUID TO BE AEROSOLIZED, AND THEN COOLING THE AEROSOLIZED LIQUID DROPLETS BY PASSAGE THROUGH A GAS TO A TEMPERATURE APPRECIABLY BELOW THE DECOMPOSITION TEMPERATURE OF THE LIQUID.
