Sodium Sulfite Anhydrous is white liquid crystal or powder, odorless. sodium sulfite anhydrous is easily soluble in water, very slightly soluble in ethanol,  and almost insoluble in ether.

Sodium sulfite anhydrous soluble in water (at 0℃,12.54g/100ml water;at 80℃28.3g/100ml water), at 33.4℃, the solubility is the highest and reach 28%, aqueous solution shows alkaline with PH value 9 to 9.5. Very slightly soluble in ethanol, insoluble in liquid chlorine and ammonia. Easy to be oxidized into sodium sulfate in air, to meet high temperature sodium sulfite anhydrous is decomposed into sodium sulfide. Sodium sulfite anhydrous is enhanced reducing agent, act with sulfur dioxide and generate Sodium Bisulfite. Act with strong acid and generate the corresponding salt.

Qingdao Tianya Chemical Co., Ltd is the leading manufacturer of Sodium Sulfite Anhydrous in China, we are producing and supplying high quality Sodium Sulfite Anhydrous, welcome to contact with us and buy Sodium Sulfite Anhydrous.

Applicaion of Sodium Sulfite Anhydrous

1. Sodium sulfite anhydrous is used for determination of trace analysis and preparation of developing liquid of tellurium and niobium, also used for reductant.

2. Sodium sulfite anhydrous is used for artificial fiber stabilizer, fabric bleaching agent, photographic developer, dye bleaching agent, spices and dye reducing agent, paper lignin removal agent, and etc..

3. Sodium sulfite anhydrous is used for general analytical reagents and photosensitive resistance materials.

4. Sodium sulfite anhydrous is used for reducing bleaching agent. sodium sulfite anhydrous has bleaching effect for food and has strong inhibiting effect for oxidase in plant food. sodium sulfite anhydrous can be used for preserves, maximum level is 2.0g/kg; sodium sulfite anhydrous also can be used for Glucose, liquid glucose, sugar, rock sugar, malt sugar, candy, bamboo shoots, mushrooms, and canned mushroom, grape and black currant juice concentrate, maximum level is 0.60g/kg. The residual amount of Bamboo shoots, mushrooms and mushroom, canned fruit, grapes and blackcurrant juice concentrate≤0.05g/kg, calculated by SO2. Potato starch residue ≤0.03g/kg. The residual amount of biscuits, sugar, fans and other varieties less than 0.1g/kg, The residual amount of liquid glucose not more than 0.2g/kg.

5. Sodium sulfite anhydrous is used for deoxidizing agent and bleaching agent in dyeing and printing industry. It is used for boiling of all kinds of cotton fabrics, can prevent the local oxidation of cotton fiber and fiber strength, and improve the whiteness of the cooking. sodium sulfite anhydrous is used for developer in photographic industry. sodium sulfite anhydrous is used for reducing agent of m-Phenylenediamine, 2,5- two chlorine, anthraquinone-1-sulfonic acid, 1-Aminoanthraquinone, paramisan sodium production in organic industry, it can prevent oxidation of semi product in the process of reaction. In papermaking industry sodium sulfite anhydrous is used as a lignin removal agent. In textile industry sodium sulfite anhydrous is used as a stabilizer for artificial fibers. In electronic industry sodium sulfite anhydrous is used for manufacturing photosensitive resistance. In water treatment industry sodium sulfite anhydrous is used for treatment of electroplating wastewater and drinking water.

6. Sodium sulfite anhydrous is used as bleaching agents, preservatives, loose agents, antioxidants In food industry . Sodium sulfite anhydrous is also used for pharmaceutical synthesis, and used for reducing agent in dehydrated vegetables production.

7. Sodium sulfite anhydrous is used to produce Sulfite Cellulose Ester, sodium hyposulfite, organic chemical medicines, bleached woven fabric, also used as reducing agent, preservative and antichlor.

8. Sodium sulfite anhydrous is used for preparation of sulfur dioxide in laboratory.
