THE products formed at the anode are then neutralized using sulfuric acid .Mass balance to produce 5000 tonnes a year of glycolic acid. the conversion of ethylene glycol is 60%. Selectivity of 85% sodium glycolate , 3% sodium formate and 2% sodium oxalate . How much water is needed , How much na oh is required, How much H2so4 is required , How much air is needed to dry, And how hydrogen is produced,sodium sulphate produced. Produce a table of mass in and mass produced /out
