Sodium Hydroxide Flakes/Sodium Hydroxide Pearls 99%

We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:

Sodium hydroxide  or Caustic soda is a white, odorless, nonvolatile alkaline material marketed in solid form as pellets, flakes, clumps, or sticks. Its solubility in water is 111% by weight and a vapor pressure of 0mmHg (NIOSH, 1994). This product can react with tricholoethylene (TCE) to form flammable dichloroacetylene and with metals to form hydrogen gas (OEHHA, 1993). Its reactivity with metals should be considered in regards to storage units and containers.

4)     Uses:

Sodium hydroxide is sold commercially as anhydrous flakes or pellets or as 30-50%  aqueous solutions. It has countless industrial uses and is one of the top 10 chemical in terms of production and use on a global scale. Approximately 15 million tons of sodium hydroxide is used annually. Its largest use, consuming about half of its production, is as a base in producing other chemicals. It is used to control pH and neutralize acids in chemical processes. The paper industry makes extensive use of sodium hydoxide in the pulping process. Sodium hydroxide is used to separate fibers by dissolving the connecting lignin. It is used in a similar fashion in the production of rayon from cellulose. Sodium hydroxide is a key chemical in the soap industry.In the saponification process, triglycerides obtained from animal and plants are heated in abasic solution to give glycerol and soap:

Sodium hydroxide is used in the textile industry for bleaching and treating textiles to makethem dye more readily. The petroleum industry uses sodium hydroxide in drilling muds and asa bactericide. Sodium hypochlorite (NaOCl) is used extensively for cleaning and as a disinfectant .Common household bleach consists of about 5% sodium hypochlorite solution. Sodium hypochlorite is prepared by reacting chlorine with sodium hydroxide: Cl2(g) + 2NaOH(aq) →NaOCl(aq) + NaCl(aq) + H2O(l). Sodium hydroxide is used in the food industry for   peeling fruits and vegetables. Sodium hydroxide is a minor ingredient in many common household products, but in a few it may constitute more than half of the product. Dranocrystals contain between 30% and 60% sodium hydroxide and some drain cleaners can consist of 100% sodium hydroxide.
