二磷酸

CO is used to produce formate,formic acid and oxalic acid by reacting with alkaline,in which the CO usually from coal vaporization is replaced by the CO from tail gas of yellow phosphorus production,by-reaction between thermal phosphoric acid and formate or oxalate to produce formic acid or oxalic acid,and by product dihydric phosphates.
