Make a scheme for obtaining ethanol from starch. Above the arrows of the transitions, indicate the conditions for the implementation of the reactions and the formulas of the substances necessary for this
(C6H10O5) n + n H2O t, H2SO4 → n C6H12O6 starch glucose Stepwise hydrolysis of starch occurs (m <n): (C6H10O5) n → (C6H10O5) m → x C12H22O11 → n C6H12O6 → enzymes, fermentation 2 starch C2H5OH + CO2 ↑. ethanol Starch is widely used in food, fermentation, pharmaceutical, textile industries.
