Definitions
- the present disclosure relates to azeotropic and azeotrope-like compositions of E-1 ,3,4,4,4-pentafluoro-3-trifluoromethyl-1 -butene and Z- 1 ,1 ,1 ,4,4,4-hexafluoro-2-butene.
- CFCs chlorofluorocarbons
- HCFCs hydrochlorofluorocarbons
- HFCs hydrofluorocarbons
- the HFCs do not contribute to the destruction of stratospheric ozone, but are of concern due to their contribution to the "greenhouse effect", i.e., they contribute to global warming. As a result of their contribution to global warming, the HFCs have come under scrutiny, and their widespread use may also be limited in the future. Thus, there is a need for compositions that do not contribute to the destruction of stratospheric ozone and also have low global warming potentials (GWPs).
- GWPs global warming potentials
- composition consisting essentially of (a) E-HFO-1438ezy and a second component present in an effective amount to form an azeotrope or azeotrope like mixture.
- the second component includes Z-HFO-1336mzz or cyclopentane.
- FIG. 1 - FIG. 1 is a graphical representation of an azeotropic composition of E-HFO-1438ezy and Z-HFO-1336mzz at a temperature of about 25 °C.
- FIG. 2 - FIG. 2 is a graphical representation of an azeotropic composition of E-HFO-1438ezy and cyclopentane at a temperature of about 25.0 °C.
- a pure single component or an azeotropic or azeotrope-like mixture is desirable.
- a blowing agent composition also known as foam expansion agents or foam expansion compositions
- the composition may change during its application in the foam forming process. Such change in composition could detrimentally affect processing or cause poor performance in the application.
- a refrigerant is often lost during operation through leaks in shaft seals, hose connections, soldered joints and broken lines. In addition, the refrigerant may be released to the atmosphere during maintenance procedures on refrigeration equipment.
- the refrigerant composition may change when leaked or discharged to the atmosphere from the refrigeration equipment.
- the change in refrigerant composition may cause the refrigerant to become flammable or to have poor refrigeration performance.
- HFO-1438ezy may exist as one of two configurational isomers, E or
- HFO-1438ezy refers to the isomers, Z-HFO-1438ezy or E-HFO-1438ezy, as well as any combinations or mixtures of such isomers.
- HFO-1336mzz may exist as one of two configurational isomers, E or Z.
- HFO-1336mzz as used herein refers to the isomers, Z-HFO- 1336mzz or E-HFO-1336mzz, as well as any combinations or mixtures of such isomers.
- the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion.
- a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
- “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
- Z-HFO-1336mzz is a known compound, and can be made by the selective hydrogenation of hexafluoro-2-butyne with a Lindlar catalyst and hydrogen, such as disclosed in U.S. Patent Publication No. 2008- 0269532.
- compositions consisting essentially of (a) E-HFO-1438ezy and (b) Z-HFO-1336mzz; wherein the Z-HFO-1336mzz is present in an effective amount to form an azeotropic or azeotrope-like mixture with E-HFO-1438ezy.
- effective amount is meant an amount of Z-HFO-1336mzz, which, when combined with E-HFO-1438ezy, results in the formation of an azeotropic or azeotrope-like mixture.
- effective amount an amount of cyclopentane, which, when combined with E-HFO-1438ezy, results in the formation of an azeotropic or azeotrope-like mixture.
- This definition includes the amounts of each component, which amounts may vary depending on the pressure applied to the composition so long as the azeotropic or azeotrope-like compositions continue to exist at the different pressures, but with possible different boiling points.
- effective amount includes the amounts, such as may be expressed in weight or mole percentages, of each component of the compositions of the instant invention which form azeotropic or azeotrope- like compositions at temperatures or pressures other than as described herein.
- an azeotropic composition is an admixture of two or more different components which, when in liquid form under a given pressure, will boil at a substantially constant temperature, which temperature may be higher or lower than the boiling temperatures of the individual components, and which will provide a vapor composition essentially identical to the overall liquid composition undergoing boiling, (see, e.g., M. F. Doherty and M.F. Malone, Conceptual Design of
- an azeotropic composition is that at a given pressure, the boiling point of the liquid composition is fixed and that the composition of the vapor above the boiling composition is essentially that of the overall boiling liquid composition (i.e., no
- an azeotropic composition may be defined in terms of the unique relationship that exists among the components or in terms of the compositional ranges of the components or in terms of exact weight percentages of each component of the composition characterized by a fixed boiling point at a specified pressure.
- an azeotrope-like composition means a composition that behaves like an azeotropic composition (i.e., has constant boiling characteristics or a tendency not to fractionate upon boiling or evaporation). Hence, during boiling or evaporation, the vapor and liquid compositions, if they change at all, change only to a minimal or negligible extent. This is to be contrasted with non-azeotrope-like compositions in which during boiling or evaporation, the vapor and liquid compositions change to a substantial degree.
- compositions with a difference in dew point pressure and bubble point pressure of less than or equal to 5 percent (based upon the bubble point pressure) is considered to be azeotrope-like.
- Relative volatility is the ratio of the volatility of component 1 to the volatility of component 2.
- the ratio of the mole fraction of a component in vapor to that in liquid is the volatility of the component.
