過(guò)硫酸銨呈白色晶體粉末狀，常常會(huì)作為引發(fā)劑，在化學(xué)反應(yīng)中引發(fā)聚合反應(yīng)。然而有的時(shí)候過(guò)硫酸銨會(huì)出現(xiàn)失效的情況，那么，這是為什么呢？過(guò)硫酸銨在使用的時(shí)候一定要現(xiàn)配現(xiàn)用嗎？過(guò)硫酸銨在使用的時(shí)候還需要注意哪些呢？接下來(lái)可以和小編一起了解一下。

Ammonium persulfate is a white crystalline powder, often used as an initiator to initiate polymerization in chemical reactions. However, sometimes ammonium persulfate will fail, so why? Does ammonium persulfate have to be prepared and used now? What else should we pay attention to when using ammonium persulfate? Next, we can learn about it with Xiaobian.

過(guò)硫酸銨在使用的時(shí)候是需要現(xiàn)配現(xiàn)用的。已經(jīng)配置了15%的過(guò)硫酸銨溶液放置時(shí)間過(guò)長(zhǎng)就會(huì)失效，是由于過(guò)硫酸銨在水中溶解較快，并且在室溫下，其穩(wěn)定性差，即使在避光或無(wú)空氣的情況下，也能在水溶液中被水解為硫酸氫銨和過(guò)氧化氫，后者分解為水和氧氣。在鹽的作用下，雙氧水更易于被破壞。因此，長(zhǎng)期使用的過(guò)硫酸銨溶液就會(huì)失去作用。

When ammonium persulfate is used, it needs to be prepared and used. The 15% ammonium persulfate solution that has been prepared will fail if it is stored for a long time, because ammonium persulfate dissolves quickly in water, and its stability is poor at room temperature. Even in the absence of light or air, it can be hydrolyzed into ammonium bisulfate and hydrogen peroxide in aqueous solution, and the latter can be decomposed into water and oxygen. Hydrogen peroxide is easier to be destroyed under the action of salt. Therefore, the ammonium persulfate solution used for a long time will lose its function.

過(guò)硫酸銨的變質(zhì)的因素是由于它在室溫下會(huì)在水中溶解，而在常溫下，固體的過(guò)硫酸銨穩(wěn)定性很好，只要不在高溫、潮濕和強(qiáng)光條件下，它就能一直儲(chǔ)存。

The deterioration factor of ammonium persulfate is that it will be dissolved in water at room temperature. At room temperature, the solid ammonium persulfate is very stable. As long as it is not under high temperature, humidity and strong light, it can be stored all the time.

過(guò)硫酸銨操作時(shí)避免產(chǎn)生粉塵。避免與還原劑、活性金屬粉末接觸。搬運(yùn)時(shí)要輕裝輕卸，防止包裝及容器損壞。禁止震動(dòng)、撞擊和摩擦。配備相應(yīng)品種和數(shù)量的消防器材及泄漏應(yīng)急處理設(shè)備。倒空的容器可能殘留有害物。

Avoid dust during ammonium persulfate operation. Avoid contact with reducing agent and active metal powder. Handle with care to prevent damage to packaging and containers. Vibration, impact and friction are prohibited. Provide fire fighting equipment and leakage emergency treatment equipment of corresponding types and quantities. Empty containers may contain harmful substances.

在使用過(guò)硫酸銨的過(guò)程中，應(yīng)避免產(chǎn)生粉塵。避免接觸還原劑，活性金屬粉末。運(yùn)輸時(shí)應(yīng)輕放輕放，避免包裝和容器的損傷。禁止振動(dòng)、碰撞以及摩擦。配備相應(yīng)種類和數(shù)量的滅火設(shè)備，以及緊急情況下的處置設(shè)施。傾倒后的容器中可能會(huì)存在有害物質(zhì)殘留，需要及時(shí)處理。

In the process of using ammonium persulfate, dust should be avoided. Avoid contact with reducing agent and active metal powder. Handle with care during transportation to avoid damage to packaging and containers. Vibration, collision and friction are prohibited. Provide corresponding types and quantities of fire extinguishing equipment and disposal facilities in case of emergency. There may be residual harmful substances in the dumped container, which needs to be disposed in time.
