Price of persulfate an, sodium
Thread Content
Has anyone been aware of the market prices for persulfates in recent years? I earnestly ask for your help.
Hehe, I’m pretty familiar with this. Normally, the price of sodium is between 6,500 and 7,000 yuan per ton, while ammonium costs between 4,200 and 4,500 yuan per ton. From September to December 2008, the price of sodium reached as high as 13,000 yuan per ton, and that of ammonium peaked at 8,000 yuan per ton. In January 2009, the price of sodium was 5,300 yuan per ton, and ammonium cost between 3,600 and 3,800 yuan per ton. In February, the price of sodium was 5,500 yuan per ton, with ammonium costing around 4,000 yuan per ton. Currently, the price of sodium is 6,500 yuan per ton, and ammonium is 4,500 yuan per ton. There will be further price increases in the near future
What a timely help! Thank you so much! One more thing I would like to ask regarding is the consumption in the production of AN persulfate. The data provided in the second volume of the \"Inorganic Salts Industry Handbook\" on the consumption involved in the production of AN persulfate is as follows: AN sulfuric acid – 1.033 ； Sulfuric acid 0.592. However, based on the reaction equation: H2SO4 + (NH4)2SO4 = (NH4)2S2O8 + H2, the theoretical amount required is: Sulfuric acid: 0.579 ； Sulfuric acid 0.430. There is a significant difference between the two, especially in terms of the consumption of sulfuric acid An, which seems to have exceeded normal levels of loss, raising doubts about the reliability of the data in the Manual. What is the real situation? I have another question.
