Embodiment 1

[0102] In this example, use an internal volume of 19800cm 3 An iron (SPCC) container (manufactured by DAIKAN Co., Ltd., model number 20C-285T-100810) was used as the storage container main body. The plate thickness of the iron container is 0.8mm (container trunk) and 1.0mm (top and bottom). The material of the liquid contact part is epoxy-phenolic resin (manufactured by Toyo Ink Co., Ltd., model E-90-NSP), and the thickness is about 5 μm. About 2 kg of HCFO-1233zd(Z) (purity: 99.97%) was placed in this storage container for HCFO-1233zd(Z), and the screw cap was tightened, and it was left to stand at normal temperature for 6 months.

Embodiment 1 and

[0135] Table 1 shows the analysis results of the acid content, water content, purity, evaporation residue, and color tone of Example 1 and Comparative Examples 1 to 3. Table 1 shows the analysis results of acid content, moisture, purity, evaporation residue, and color tone of HCFO-1233zd(Z) (purity: 99.97%) before storage.

[0137]

[0138] In Comparative Example 1 and Comparative Example 3, a significant increase in water content was observed. With respect to Comparative Example 2, a significant rise in evaporation residue was observed. On the other hand, in Example 1, the acid content, moisture, purity, and evaporation residue contained in HCFO-1233zd(Z) were within the range of error and did not change significantly before and after the test.

Embodiment 2

[0140] In this example, use an internal volume of 19800cm 3 An iron (SPCC) container (manufactured by DAIKAN Co., Ltd., model number 20C-285T-100810) was used as the storage container main body. The plate thickness of the iron container is 0.8mm (container trunk) and 1.0mm (top and bottom). The material of the liquid contact part is epoxy-phenolic resin (manufactured by Toyo Ink Co., Ltd., model E-90-NSP), and the thickness is about 5 μm. About 2 kg of HCFO-1233zd(Z) (purity: 99.97%) was placed in this storage container for HCFO-1233zd(Z), and the screw cap was tightened, and left still at 35° C. for 6 months.

Abstract

The purpose of the present invention is to provide a storage container and a storage method, which retain the quality of Z-1-chloro-3, 3, 3-trifluoropropene as a solvent or a cleaning agent, and whichachieve safe and stable storage and transportation thereof at low cost. A storage container for HCFO-1233zd (Z) according to the present invention, which is filled with HCFO-1233zd (Z), is characterized in that at least the material for a liquid contact part is selected from the group consisting of an epoxy/phenolic resin, a phenolic resin, a phenolic/butyral resin, a stainless steel, iron phosphate, zinc phosphate and glass.

Description

technical field [0001] The present invention relates to a storage container and storage method for Z-1-chloro-3,3,3-trifluoropropene. Background technique [0002] In order to prevent global warming and damage the ozone layer, various alternatives to CFCs have been proposed so far. In order to protect the ozone layer, hydrofluorocarbons (HFCs) that do not generate chlorine radicals that cause ozone layer destruction have been widely used. However, HFCs generally have a long atmospheric lifetime and have a large impact on the global environment such as global warming. Regulation of HFCs is progressing in the market, and as substitutes for them, hydrofluoroolefins (HFOs) which have double bonds in the molecule and have a short atmospheric lifetime, and hydrochlorofluoroolefins (HCFOs) in which chlorine is introduced will soon be launched. [0003] HCFO has the following advantages: not only low global warming coefficient, but also low toxicity, high compatibility, and higher...
