Method for producing dust-free sodium dithionite |
| abstract |
There is disclosed a method for the production of dust-free sodium dithionite from the reaction of a alkaline formate sulfur dioxide and an alkaline metal agent in the presence of a thiosulfate reactive compound by introducing a water-soluble polymer having a molecular weight less than 60,000 and delaying the start of the alkaline metal agent until the sodium formate and the sulfur dioxide have begun to be introduced into the reactor. |
