順酐（Phthalic anhydride）是一種有機化合物，儲存時需要注意以下幾點：

Phthalic anhydride is an organic compound that needs to be stored with the following precautions:

包裝和密封：在儲存順酐時，應選擇適當的包裝材料，如耐腐蝕性好的塑料桶或不銹鋼容器。確保包裝完整且密封良好，以防止水分、氧氣和其他雜質進入，避免對順酐產生負面影響。

Packaging and sealing: When storing maleic anhydride, appropriate packaging materials should be selected, such as plastic drums or stainless steel containers with good corrosion resistance. Ensure that the packaging is complete and well sealed to prevent the entry of moisture, oxygen, and other impurities, and to avoid negative effects on maleic anhydride.

溫度控制：順酐的儲存溫度應控制在室溫下，避免過高或過低的溫度。極端溫度可能導致順酐分解、揮發或結晶，從而降低其質量和穩定性。此外，應避免陽光直射和熱源附近的儲存，以防止溫度變化。

Temperature control: The storage temperature of maleic anhydride should be controlled at room temperature to avoid high or low temperatures. Extreme temperatures may cause the decomposition, volatilization, or crystallization of maleic anhydride, thereby reducing its quality and stability. In addition, direct sunlight and storage near heat sources should be avoided to prevent temperature changes.

防潮儲存：順酐對潮濕敏感，容易吸濕并形成結塊。因此，在儲存順酐時，應保持儲存環境相對干燥，并避免與水分接觸。可以使用干燥劑或濕度控制設備來控制儲存環境的濕度，以保持順酐的穩定性。

Moisture proof storage: Maleic anhydride is sensitive to moisture and easily absorbs moisture and forms clumps. Therefore, when storing maleic anhydride, the storage environment should be kept relatively dry and avoid contact with moisture. Desiccants or humidity control devices can be used to control the humidity of the storage environment to maintain the stability of maleic anhydride.

避光存放：陽光和紫外線可能會降解順酐的質量和穩定性。因此，應將順酐存放在避光的地方，更好是在暗室或遮光容器中儲存。這有助于減少光照對順酐的不利影響。

Storage away from light: Sunlight and ultraviolet radiation may degrade the quality and stability of maleic anhydride. Therefore, maleic anhydride should be stored in a dark room or shaded container, preferably in a dark place. This helps to reduce the adverse effects of light on maleic anhydride.

定期檢查和記錄：定期檢查儲存的順酐是否存在異常，如結塊、變色或異味等。同時，建議記錄順酐的儲存時間、批次和其他相關信息，以便追蹤其使用和管理情況，并及時發現任何問題。

Regular inspection and recording: Regularly inspect the stored maleic anhydride for abnormalities such as clumping, discoloration, or odor. At the same time, it is recommended to record the storage time, batch number, and other relevant information of maleic anhydride in order to track its use and management, and promptly identify any issues.

綜上所述，順酐的儲存需要注意包裝和密封、溫度控制、防潮儲存、避光存放以及定期檢查和記錄。正確的儲存方法可以確保順酐的質量和穩定性，延長其有效使用期限。請注意，具體的儲存要求可能因廠家指導和產品規格而有所不同，建議參考相關的技術文檔和供應商建議。

In summary, the storage of maleic anhydride requires attention to packaging and sealing, temperature control, moisture-proof storage, dark storage, and regular inspection and recording. The correct storage method can ensure the quality and stability of maleic anhydride, and extend its useful life. Please note that the specific storage requirements may vary depending on the manufacturer's guidance and product specifications. It is recommended to refer to relevant technical documents and supplier recommendations.
