Glycolic acid is produced electrochemically from ethylene glycol under alkaline conditions(naoh). Hydrogen is produced at the cathode, formic acid and oxalic acid are side products Mass balance to produce 5000 tonnes a year of glycolic acid. the conersion of ethylene glycol is 60%. Selectivity of 85% glycolic acid , 3% formic acid and 2% oxalic acid. 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.
