497-19-8 Usage

Sodium carbonate is white odourless powder, while it's Molecular Formula is Na2CO3. It is a sodium salt of carbonic acid. One of most important application of sodium carbonate is for the manufacturing of glass. Sodium carbonate (Na2CO3, SC) which exist naturally and can be obtained directly from the nature, can also activate the slag. It is the important raw material for making glass, soaps, detergents, textiles, leather, spices, dyes, medicines, etc. It can be used for analysis reagents and also used for the pharmaceutical industry and photoengraving. Sodium carbonate was used as an activator in alkali-activated slag systems. Sodium carbonate activated slag can be used as an alternative to Portland cement.

Compared to Na2SiO3, sodium carbonate (Na2CO3) can be a promising substitution with lower environmental impact, together with wide availability and chemical stability, and success has been achieved in utilizing Na2CO3 in the production of normal-strength geopolymer.

Process development for sodium carbonate pretreatment and enzymatic saccharification of rice straw for bioethanol production

B Singh, A Kumar

, Biomass and bioenergy, 2020

Initially, sodium carbonate pretreatment of rice straw followed by saccharification using partially purified cellulolytic enzymes of thermophilic mould Myceliophthora thermophila BJTLRMDU3 (20 U/g) at 60 °C and pH 5.0 after 6 h, released about 3-fold more reducing sugars with autoclaving (154.93 mg/g substrate) as compared to room temperature (51.01 mg/g substrate).
