Sodium sulfate Usage And Synthesis
The main functionSodium sulfate is an important raw material in the manufacturing of glass and paper with the maximum usage amount in the paper and cellulose industry which accounts for around 70% of the total amount. Sodium sulfate is the component of synthetic detergent and is a neutral salt. It can be added to the detergent to reduce the surface tension as well as increases the solubility of the detergent. It is also be used as the dye diluent and the auxiliary agent of the dye printing, as direct dyes, sulfur dyes, vat dyes and other accelerant of dyed cotton fiber, as retarding agent for direct dye silk. In the chemical industry, it can be used as the raw material for the manufacturing of sodium sulfide, gypsum, sodium silicate and other chemical products. It has been now developed of the method for making sulfuric a-cid, sulfur, soda ash, ammonium sulfate and other products with sodium sulfate. However, due to the high cost of these methods, it has not yet been widely applied. It has been commonly used by laboratory system for using sodium sulfate as cold agent. Glauber's salt has been used as a laxative medicine. The sodium sulfate entering into the body is largely stuck in the gastrointestinal tract without being absorbed and being maintained at certain penetration. It can increase the volume of the intestines and induce intestinal peristalsis with diarrhea effect. Sodium sulfate is the antidote of barium and lead poisoning. Upon lead poisoning, people can apply gastric lavage with 10% Glauber's salt or orally administer 1 to 2% sodium sulfate solution.
The above information is edited by the chemicalbook of Dai Xiongfeng.
Pharmacological effectsApply oral administration of small amount with its ionic and osmotic pressure effect being able to slightly stimulate the digestive tract mucosa and causes a slight increase of the gastrointestinal secretion and a slight increase in the movement, therefore it has stomachic effect. 
Orally administer a large amount with a lot of sodium sulfate being dissolved in large amount of water for oral administration. Since the ions are not easily absorbed and can maintain large amount of water in the intestines and can mechanically stimulate the intestinal mucosa and can soften the fecal matter and accelerate the defecation. It is clinically mainly used in the treatment of large intestine constipation, eliminating the intestinal toxins as well as getting rid of parasites.
