Description

TECHNICAL FIELD The present invention relates a storage container and a storage method of Z-1-chloro-3,3,3-trifluoropropene. BACKGROUND ART In order to prevent global warming and ozone layer depletion, various Freon substitutes have been proposed so far. In order to protect the ozone layer, hydrofluorocarbons (HFCs), which do not generate chlorine radicals causing ozone layer depletion, spread widely. However, HFCs generally have a long atmospheric lifetime and have a significant influence on global environments, for example, cause global warming or the like. In the commercial markets, regulations on HFCs are being made progressively. As a substitute for HFCs, hydrofluoroolefin (HFO), which includes a double bond in a molecule and has a short atmospheric lifetime, and hydrochlorofluoroolefin (HCFO), which is obtained by incorporation of chlorine into HFO, have been introduced. HCFO has a low global warming potential, is relatively low in toxicity, and is highly compatible. HCFO also has a higher boiling point than that of HFO, and specifically has an advantage of being capable to form a high density foam as a foaming agent. 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) is available in geometrical isomers of trans isomer (E isomer) and cis isomer (Z isomer), which are respectively referred to as HCFO-1233zd (E) and HCFO-1233zd (Z). HCFO-1233zd (E) is now commercially produced as a next-generation foaming agent. For HCFO-1233zd (Z), uses as a solvent and a detergent have been proposed (Patent Literature 1). HCFO-1233zd (Z) is known to cause resin erosion due to its high solubility, such as acrylonitrile-butadiene-styrene (ABS) plastics, high impact styrene black, acrylic resin, polycarbonate and the like (Patent Literature 2).
