過硫酸鈉廠家屬于非易燃品，但由于能釋放氧而有助燃作用，因此必須在一定條件下儲存。必須存放在干燥、密閉的容器中，其次應避免陽光直射、熱源、潮濕等不利因素。另外，一些雜質(zhì)如臟物、鐵銹、少量金屬以及還原劑可能引起過硫酸銨的分解，在存放和使用過程中也必須注意。由于潮濕的過硫酸銨粉末及其水溶液有漂白和輕微的腐蝕作用，因此使用過程中應避免眼睛、皮膚和衣物直接與其接觸。
Sodium persulfate is a nonflammable product, but it has combustion supporting effect because it can release oxygen, so it must be stored under certain conditions. First of all, it must be stored in a dry and airtight container. Second, it should avoid direct sunlight, heat source, humidity and other adverse factors. In addition, some impurities such as dirt, rust, a small amount of metal and reducing agent may cause the decomposition of ammonium persulfate, which must also be noted in the storage and use process. As the wet ammonium persulfate powder and its aqueous solution have bleaching and slight corrosion, direct contact with eyes, skin and clothes should be avoided during use.
過硫酸鈉又稱過二硫酸鈉。白色晶體或結(jié)晶性粉末。無嗅。無味。分子式Na2S2O8，相對分子質(zhì)量238.13。常溫下逐漸分解，加熱或在乙醇中可迅速分解，分解后放出氧氣并生成焦硫酸鈉。濕氣及鉑黑、銀、鉛、鐵、銅、鎂、鎳、錳等金屬離子或它們的合金均可促進分解，高溫(200℃左右)急劇分解，放出過氧化氫。易溶于水(20℃時70.4)。有強氧化性。對皮膚有強烈刺激性，長時間接觸皮膚，可引起過敏癥，操作時應注意。大鼠經(jīng)口LD50 895mg/kg。密封保存。實驗室通過加熱過硫酸鈉廠家與苛性鈉或碳酸鈉溶液，除去氨和二氧化碳而得過硫酸鈉。
Sodium persulfate is also called sodium persulfate. White crystal or crystalline powder. Odorless. Tasteless. Molecular formula Na2S2O8, relative molecular weight 238.13. It can decompose gradually at room temperature, and decompose rapidly when heated or in ethanol. After decomposition, oxygen is released and sodium pyrosulfate is generated. Wet gas, platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote decomposition. At high temperature (about 200 ℃), they decompose rapidly and release hydrogen peroxide. Soluble in water (70.4 at 20 ℃). Strong oxidation. It has a strong irritant to the skin. Long time contact with the skin can cause allergies. Attention should be paid to the operation. The oral LD50 895mg / kg of rats. Sealed storage. The laboratory obtains sodium persulfate by heating the sodium persulfate manufacturer and caustic soda or sodium carbonate solution to remove ammonia and carbon dioxide.
過硫酸鈉廠家具有強氧化性，可用作氧化劑，可將Cr3+、Mn2+等氧化成相應的高氧化態(tài)化合物，當有Ag+存在時，可促進上述氧化反應；利用其氧化性可用作漂白劑、金屬表面處理劑、化學試劑；醫(yī)藥原料；電池、乳液聚合反應的促進劑和引發(fā)劑。
Sodium persulfate plant furniture has strong oxidability, can be used as oxidant, can oxidize Cr3+, Mn2+ and so on to the corresponding high oxidation state compounds, when Ag+ exists, it can promote the above oxidation reaction; its oxidation can be used as bleaching agent, metal surface treatment agent, chemical reagents, medicine raw materials, battery and emulsion polymerization accelerator and initiator.
?。?）硫酸銨水溶液電解氧化生成過硫酸銨，再與氫氧化鈉進行復分解反應，將副產(chǎn)的氨逐出后，再減壓濃縮、結(jié)晶、干燥，可得過硫酸鈉。(NH4)2S2O8+2NaOH→Na2S2O8+2NH3+2H2O。
(1) sodium persulfate can be obtained by electrolysis oxidation of ammonium sulfate aqueous solution to produce ammonium persulfate, and then re decomposition reaction with sodium hydroxide. The by-product ammonia is ejected, and then concentrated, crystallized and dried under reduced pressure. (NH4)2S2O8+2NaOH→Na2S2O8+2NH3+2H2O。
?。?）電解冷硫酸可制得過二硫酸，再與堿作用，可制得過硫酸鈉。（I) 2HSO4--2e→H2S2O8 （II）H2S2O8+2NaOH→Na2S2O8+2H2O。
(2) sodium persulfate can be prepared by electrolysis of cold sulfuric acid and alkali. （I) 2HSO4--2e→H2S2O8 （II）H2S2O8+2NaOH→Na2S2O8+2H2O。
過硫酸鈉廠家是一種白色無味晶體、、或粉末或粉末，，被乙醇分解，常溫時穩(wěn)定性好定性好。常作強氧化劑使用常作強氧化劑使用，也可用作單體聚合引發(fā)劑也可用作單體聚合引發(fā)劑。它幾乎不吸潮，便于儲存便于儲存，使用方便使用方便。
Sodium persulfate is a kind of white and tasteless crystal, powder or powder, which is decomposed by ethanol and has good stability and quality at room temperature. Often used as strong oxidant often used as strong oxidant, can also be used as monomer polymerization initiator can also be used as monomer polymerization initiator. It is almost non hygroscopic, convenient for storage, convenient for use, convenient and safe.
