थोडक्यात उत्तर
उत्तर
Commercially, on a large scale, glucose is prepared by hydrolysis of starch with dilute sulphuric acid. Starchy material is mixed with water and dilute sulphuric acid and heated at 393 K under 2 to 3 - atm pressure. Starch is hydrolysed to give glucose.
\[\ce{\underset{(Starch)}{(C6H10O5)_n} + n H2O ->[H⊕][393K, 2-3 atm] \underset{(Glucose)}{n C6H12O6}}\]
