About Us
Why you should choose TNN's products
Anhydrous sodium sulfate, with the chemical formula Na2SO4, is a white crystalline solid that is widely used in chemical, pharmaceutical, textile and other fields. However, it is not easy to prepare high-purity anhydrous sodium sulfate. This article will give you a detailed introduction to how our suppliers produce high-purity anhydrous sodium sulfate to help you succeed in laboratory or industrial production.
(1) Raw material selection and processing
1. Choose high-quality sodium sulfate raw materials: ensure high purity of raw materials and no impurities.
2. Grind and screen the raw materials: Grind the sodium sulfate raw materials into fine powder and screen them through a screen to remove larger particles and impurities.
(2)Control of reaction conditions
1. Temperature control: The preparation of anhydrous sodium sulfate usually uses pyrolysis reaction, and the reaction temperature needs to be controlled within an appropriate range to ensure the smooth progress of the reaction.
2. Pressure control: The reaction is carried out in a closed reaction vessel, and the reaction rate and product purity can be controlled by adjusting the pressure.
(3)Solvent selection and treatment
1. Select the appropriate solvent: According to the reaction conditions and the properties of the product, select the appropriate solvent for the reaction. Commonly used solvents include sulfuric acid, phosphoric acid, etc.
2. Purify the solvent: remove impurities in the solvent through distillation, filtration and other methods to ensure the purity of the solvent.
(4)Reaction process control
1. Reaction time control: Control the reaction time according to the reaction rate and product purity requirements to avoid too long or too short reaction time.
2. Stirring speed control: By adjusting the stirring speed, ensure that the reactants are fully mixed and improve the reaction efficiency and product purity.
(5)Separation and purification of products
1. Cooling crystallization: Cool the reaction mixture to an appropriate temperature to crystallize the product.
2. Filtration and washing: Separate the crystallized product from the mother liquor by filtration, and wash with a pure solvent to remove residual impurities.
3. Drying and grinding: Dry the washed product at an appropriate temperature and grind it into fine powder to improve the purity and fluidity of the product.
(6)Quality inspection and analysis
1. Appearance inspection: Observe the color, shape, particle size and other appearance characteristics of the product to determine its purity.
2. Chemical analysis: Through chemical reactions and instrumental analysis, the chemical composition of the product is detected to ensure that its purity meets the requirements.
