Abstract: PURPOSE:To prepare a vaporization controller capable of covering the surface of vaporizable liquefied gases including toxic and irritative gases and thereby suppressing their vaporization urgently by mixing together a specified paraffinic hydrocarbon and a specified naphthenic hydrocarbon. CONSTITUTION:A material for controlling the vaporization of liquefied gas is prepd. by mixing together a paraffinic hydrocarbon of formula I (wherein (n) is 10-46) and a naphthenic hydrocarbon of formula II (wherein (n) is 10-46). With this vaporization controller, the free surface of a leaking conc. ammonia solution or the like can be covered, and the vaporization of the gas can be suppressed over a long period of time. It is not readily blown off by the wind, but returns to the original position even if once drifted. The saturated hydrocarbons used therein are inert to heat, light and chemicals and long storable. They do not corrode metals and are easy to maintain and handle. Therefore, the vaporization controller makes it possible to take a sufficiently long period of time for treatment of the leaked material enough to secure a high safety.
