顺酐结块儿了,会影响使用吗?
顺酐生产厂家认为其结块是由于吸收空气中水分还原成酸的原因,顺酐吸潮造成的,变色是由于双键被氧化的缘故,可以重结晶继续,短时间内不会影响使用。
Does the agglomeration of maleic anhydride affect its use? The manufacturer of maleic anhydride believes that its agglomeration is caused by the absorption of moisture in the air to reduce to acid, and the moisture absorption of maleic anhydride is caused by the oxidation of double bonds, which can be recrystallized and will not affect its use in a short period of time.
怎么解决这个事儿呢?您可以尝试将其放在干燥通风处,结块的已经吸水变质了(反应成有机酸了),建议过筛后废弃。
How can we solve this problem? You can try placing it in a dry and ventilated place. The clumps have already absorbed water and deteriorated (reacting into organic acids). It is recommended to discard them after sieving.
此外要注意一些事项,比如:
In addition, some precautions should be taken, such as:
由于顺酐本身是一种易燃易爆的化学品,并且还具有一定的腐蚀性,长期接触会对人体造成损伤,如人体吸入含有顺酐的空气后,会出现咳嗽、淌眼泪、打喷嚏等症状,严重时,甚会使呼吸变得困难,若是皮肤与顺酐接触,则会产生红肿、疼痛的情况。
Due to the fact that maleic anhydride is a flammable and explosive chemical and has a certain degree of corrosiveness, long-term exposure can cause damage to the human body. For example, after inhaling air containing maleic anhydride, the human body may experience symptoms such as coughing, tearing, and sneezing. In severe cases, it may even make breathing difficult. If the skin comes into contact with maleic anhydride, it can cause redness, swelling, and pain.
鉴于此,应当在顺酐生产过程中,采取有效的控制措施,确保。在顺酐生产时,一旦发生跑冒滴漏等情况,必须由专人进行处理,在处理的过程中,要配戴防护用具。
In view of this, effective control measures should be taken in the production process of maleic anhydride to ensure safety. During the production of maleic anhydride, if there is any leakage or leakage, it must be handled by a dedicated person, and protective equipment must be worn during the treatment process.
尤其是贮罐及装置出现泄漏时,应在时间查明原因,采取有效的方法和措施进行紧急处理,避免顺酐大量泄漏,生产出来的顺酐产品在储存时,应置于通风条件良好的库房当中,并保证库房内保持常温,贮罐应当进行可靠接地,采取静电屏蔽措施。
Especially when there is leakage in storage tanks and devices, the cause should be identified as soon as possible, and effective methods and measures should be taken for emergency treatment to avoid a large amount of leakage of maleic anhydride. The produced maleic anhydride products should be stored in a well ventilated warehouse and ensure that the warehouse is kept at room temperature. The storage tanks should be reliably grounded and electrostatic shielding measures should be taken.
在对顺酐进行运输时,应当做好防水防潮工作,并且不得暴露在阳光下,以免顺酐升华,要做到轻拿轻放;如果顺酐起火,不得使用干粉灭火器,而是应当选用二氧化碳灭火器。更多相关内容就来我们网站

When transporting maleic anhydride, waterproof and moisture-proof measures should be taken, and it should not be exposed to sunlight to avoid sublimation of maleic anhydride. It should be handled with care; If maleic anhydride catches fire, dry powder fire extinguishers should not be used, but carbon dioxide fire extinguishers should be used.
