顺酐（Phthalic anhydride）是一种有机化合物，储存时需要注意以下几点：

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

包装和密封：在储存顺酐时，应选择适当的包装材料，如耐腐蚀性好的塑料桶或不锈钢容器。确保包装完整且密封良好，以防止水分、氧气和其他杂质进入，避免对顺酐产生负面影响。

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.

温度控制：顺酐的储存温度应控制在室温下，避免过高或过低的温度。极端温度可能导致顺酐分解、挥发或结晶，从而降低其质量和稳定性。此外，应避免阳光直射和热源附近的储存，以防止温度变化。

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.

防潮储存：顺酐对潮湿敏感，容易吸湿并形成结块。因此，在储存顺酐时，应保持储存环境相对干燥，并避免与水分接触。可以使用干燥剂或湿度控制设备来控制储存环境的湿度，以保持顺酐的稳定性。

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：阳光和紫外线可能会降解顺酐的质量和稳定性。因此，应将顺酐存放在避光的地方，更好是在暗室或遮光容器中储存。这有助于减少光照对顺酐的不利影响。

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.

定期检查和记录：定期检查储存的顺酐是否存在异常，如结块、变色或异味等。同时，建议记录顺酐的储存时间、批次和其他相关信息，以便追踪其使用和管理情况，并及时发现任何问题。

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.

综上所述，顺酐的储存需要注意包装和密封、温度控制、防潮储存、避光存放以及定期检查和记录。正确的储存方法可以确保顺酐的质量和稳定性，延长其有效使用期限。请注意，具体的储存要求可能因厂家指导和产品规格而有所不同，建议参考相关的技术文档和供应商建议。

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.
