By the way, why is soda ash more expensive than caustic soda, and where is the high cost? The more detailed, the better. It is best to attach the chemical formula and process. Thank you~

April 16, the low-end supply price of 99% flake caustic soda market is 2800-3300, with an average price of 3050; The high-end supply price is 2850-3400, and the average price is 3 125.

In April, the mainstream ex-factory price of light alkali was 1200- 1300 yuan/ton, the northeast delivery price was about 1500 yuan/ton, the ex-factory price of heavy alkali was 1400- 1450 yuan/ton, and the northeast delivery price was 65438+.

Obviously, the price of caustic soda is about twice as high as that of soda ash.

According to the current high school textbooks, soda ash mainly adopts ammonia-alkali method: NaCl+NH3+CO2+H2O = NaHCO3↓+NH4Cl, 2NaHCO3 = Na2CO3+CO2↑+H2O (heating), and caustic soda adopts chlor-alkali method: 2nNaCl+2h2o = H2 ↑+Cl2 ↑+2NaOH (electrolysis). Caustic soda is more expensive than soda ash because it consumes more electricity.
