    摘要: PROBLEM TO BE SOLVED: To provide a fumigant which replaces methyl bromide, functions as a drop-in substitute, and therefore makes an existing methyl bromide device and system to be usable.
    SOLUTION: The fumigant includes an azeotropic or azeotropic-like composition comprising a mixture of methyl iodide, 1-chloro-3,3,3-trifluoropropene, and optionally one or more of fluorocarbons and/or hydrofluorocarbons. The composition is present as a gas, at a temperature of about 30°C or below. The composition serves as a non-ozone-depleting gaseous fumigant which is useful in a variety of applications, in place of methyl bromide. The composition serves as a drop-in replacement for gaseous methyl bromide, providing the benefits of a methyl iodide fumigant, while also utilizing an existing methyl bromide device.

    摘要: PROBLEM TO BE SOLVED: To provide a ternary azeotropic composition of 2-chloro-3,3,3-trifluoropropene, 2-chloro-1,1,1,2-tetrafluoropropane and hydrogen fluoride, and an azeotropic-mixture-like composition thereof. SOLUTION: This azeotropic and the azeotrope-mixture-like compositions are comprises about 1-50 wt.% of hydrogen fluoride, and about 50-99 wt.% of organic portion comprising substantially a mixture of 2-chloro-3,3,3-trifluoropropene and 2-chloro-1,1,1,2-tetrafluoropropane (the 2-chloro-3,3,3-trifluoropropene is contained by an amount of about 50-90 wt.% in the organic portion, and the 2-chloro-1,1,1,2-tetrafluoropropane is contained by an amount of about 10-50 wt.% in the organic portion). The azeotropic and the azeotrope-mixture-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf). COPYRIGHT: (C)2010,JPO&INPIT
