Composition containing hydrofluoroolefin compound
The present invention provides a composition comprising an HFO compound, the composition having excellent stability with decomposition and oxidation of the HFO compound being inhibited, the composition having improved refrigerating capacity when used as a heat transfer medium, compared with the case in which an HFO compound is used alone. More specifically, the present invention provides a composition comprising at least one HFO compound selected from the group consisting of HFO-1234yf, (E-/Z-)HFO-1234ze, and (E-/Z-)HFO-1225ye; and a chlorine-containing compound, wherein (1) the chlorine-containing compound is at least one member selected from the group consisting of CH 2 ═CHCl, CHF═CHCl, CH 2 ═CFCl, CF 3 Cl, CH 3 Cl, CF 3 CH 2 Cl, CClF═CHCl, and CHF═CCl 2 , and (2) the chlorine-containing compound is contained in an amount ranging from 1 to 500000 mass ppm.
1. A composition comprising:
at least one HFO compound selected from the group consisting of HFO-1234yf, (E-/Z-)HFO-1234ze, and (E-/Z-)HFO-1225ye; and
a chlorine-containing compound,
wherein
(1) the chlorine-containing compound is CHF═CCl 2 , and
(2) an amount of the chlorine-containing compound in the composition is within a range of 1 to 10000 mass ppm.
2. The composition according to claim 1 , further comprising at least one HFC compound selected from the group consisting of HFC-32, HFC-134a, HFC-125, HFC-143a, and HFC-23.
3. The composition according to claim 1 , further comprising at least one lubricant selected from the group consisting of polyalkylene glycols, polyvinyl ethers, and alkylbenzenes.
4. The composition according to claim 1 , further comprising water, the water being present in an amount of 1000 mass ppm or less.
5. The composition according to claim 1 , which is at least one member selected from the group consisting of heat transfer media, foaming agents, and propellants.
6. A composition comprising:
at least one HFO compound selected from the group consisting of HFO-1234yf, (E-/Z-)HFO-1234ze, and (E-/Z-)HFO-1225ye;
a chlorine-containing compound; and
a HFC compound,
wherein
(1) the chlorine-containing compound is at least one member selected from the group consisting of CH 2 ═CHCl, CH 2 ═CFCl, and CHF═CCl 2 ,
(2) an amount of the chlorine-containing compound in the composition is within a range of 10000 to 400000 mass ppm, and
(3) the HFC compound is at least one member selected from the group consisting of HFC-32, HFC-134a, HFC-125, HFC-143a, and HFC-23.
7. The composition according to claim 6 , wherein the chlorine-containing compound is at least one member selected from CH 2 ═CHCl, and CH 2 ═CFCl, and the amount of the chlorine-containing compound in the composition is within a range of 10000 to 400000 mass ppm.
8. The composition according to claim 6 , wherein the chlorine-containing compound is at least one member selected from CH 2 ═CHCl, and CH 2 ═CFCl, and the amount of the chlorine-containing compound in the composition is within a range of 100000 to 300000 mass ppm.
9. The composition according to claim 6 , wherein a mixture of the HFO compound and the chlorine-containing compound is an azeotrope or azeotrope-like mixture.
10. The composition according to claim 6 , wherein a mixture of the HFO compound and at least one chlorine-containing compound selected from CH 2 ═CHCl, and CH 2 ═CFCl is an azeotrope or azeotrope-like mixture.
11. The composition according to claim 6 , further comprising at least one lubricant selected from the group consisting of polyalkylene glycols, polyvinyl ethers, and alkylbenzenes.
12. The composition according to claim 6 , further comprising water, the water being present in an amount of 1000 mass ppm or less.
