Abstract

A storage method of HCFO-1233zd (Z) according to an embodiment of the present invention, includes using a storage container having a liquid-contact portion thereof. The liquid-contact portion is formed of a material selected from the group consisting of epoxy-phenolic resin, phenolic resin, phenolic-butyral resin, stainless steel, iron phosphate, zinc phosphate and glass.

Claims

1. A storage method of cis-1-chloro-3,3,3-trifluoropropene (HCFO-1233zd (Z)), comprising:

using a storage container having a liquid-contact portion thereof, wherein the liquid-contact portion is formed of a material selected from the group consisting of epoxy-phenolic resin, phenolic resin, phenolic-butyral resin, iron phosphate, and zinc phosphate.

2. The storage method of HCFO-1233zd (Z) according to claim 1, wherein the material of the liquid-contact portion is selected from the group consisting of phenolic resin, phenolic-butyral resin, iron phosphate and zinc phosphate.

3. The storage method of HCFO-1233zd (Z) according to claim 2, wherein the material of the liquid-contact portion is selected from the group consisting of iron phosphate and zinc phosphate.

4. The storage method of HCFO-1233zd (Z) according to claim 1, wherein the HCFO-1233zd (Z) is stored in the storage container in a sealed manner.

5. Cis-1-chloro-3,3,3-trifluoropropene (HCFO-1233zd (Z)), having a moisture content held at 50 ppm or lower in an analysis after being stored for 6 months in a storage container in which a liquid-contact portion thereof is formed of a material selected from the group consisting of epoxy-phenolic resin, phenolic resin, phenolic-butyral resin, iron phosphate, and zinc phosphate.

6. The HCFO-1233zd (Z) according to claim 5, having an evaporation residue content held at 50 ppm or lower in an analysis after being stored for 6 months in the storage container.

7. The HCFO-1233zd (Z) according to claim 5, having a purity held at 99.5% or higher in an analysis after being stored for 6 months in the storage container.

8. The HCFO-1233zd (Z) according to claim 5, having an acid content held at 1 ppm or lower in an analysis after being stored for 6 months in the storage container.

9. The HCFO-1233zd (Z) according to claim 5, having a Hazen color index held at 20 or lower in an analysis after being stored for 6 months in the storage container.

10. The HCFO-1233zd (Z) according to claim 5, having a hue held as being colorless and transparent in an analysis after being stored for 6 months in the storage container.

11. The HCFO-1233zd (Z) according to claim 5, wherein the material of the liquid-contact portion is selected from the group consisting of phenolic resin, phenolic-butyral resin, iron phosphate and zinc phosphate.

12. The HCFO-1233zd (Z) according to claim 11, wherein the material of the liquid-contact portion is selected from the group consisting of iron phosphate and zinc phosphate.

13. A cis-1-chloro-3,3,3-trifluoropropene (HCFO-1233 zd (Z)) product, comprising at least:

HCFO-1233zd (Z); and

a storage container for HCFO-1233zd (Z) being in direct contact with HCFO-1233zd (Z) as a liquid at a liquid-contact portion thereof,

wherein the liquid-contact portion is formed of a material selected from the group consisting of epoxy-phenolic resin, phenolic resin, phenolic-butyral resin, iron phosphate, zinc phosphate.

14. The HCFO-1233zd (Z) product according to claim 13, wherein the material of the liquid-contact portion is selected from the group consisting of phenolic resin, phenolic-butyral resin, iron phosphate and zinc phosphate.

15. The HCFO-1233zd (Z) product according to claim 14, wherein the material of the liquid-contact portion is selected from the group consisting of iron phosphate and zinc phosphate.

16. The HCFO-1233zd (Z) product according to claim 15, wherein the storage container for HCFO-1233zd (Z) is sealable.
