Oxysulfonation of coke coal by nitrosylsulfuric acid

The interaction of coke coal with nitrosylsulfuric acid NOHSO 4 in acetonitrile at 20–25°C, times to 24 h, and the NOHSO 4 /coal ratio R ≤ 50 mmol/g was studied. The process leads to the formation of oxysulfonated coal accompanied by an increase in the weight (to 46%), a decrease (by a factor of 3.8...
