In recent years, with the continuous development of the economy and the level of science and technology also continues to increase, food grade potassium metabisulfite is a kind of food additives that we will use in food production and processing activities, the use of food additives such as not only improves the work efficiency, but also for our production is helpful. But a lot of people on food grade potassium potassium sulfate is not very understanding of the relevant knowledge, today we will give you a brief introduction to the food grade potassium sulfite preparation method. Hope that our introduction to all of us help, the following and a small make up to see it!
Method for preparing food grade potassium sulfite
Food grade potassium metabisulfite for sulfate of potash minerals and potassium brine as raw material to produce the Saline Lake can be prepared. Also available 98% sulfuric acid and potassium chloride in the 550 DEG C high temperature of reaction, the direct preparation of potassium sulfate, the reaction produces hydrogen chloride, water absorption, by-product hydrochloric acid, this method is the main method of Chinese industrial production of food grade potassium metabisulfite, Mann Hamm law. Reduction of pyrolysis method with alum. In Germany, the production of potassium sulfate in food grade is mainly by the production of Magnesium Sulfate ore and potassium chloride in the liquid phase reaction. Prepared by the reaction of sulfuric acid with potassium chloride. Mixed with potassium hydroxide sulfate can also get food grade potassium metabisulfite.
Through the introduction of this article, we know that the preparation method of food grade potassium metabisulfite, I believe you, this is not strange, if you are interested in our presentation, we will in the future for everyone to bring more exciting information. Our company is potassium sulphate supplier , if you have any doubts about this, you can call us, we will seriously answer, I believe we will have a harvest, please pay more attention to it!
