Chemical Products DL-Tryptophan Production Methods
Using indole and α-acetamidoacrylic acid as raw materials, after the reaction in glacial acetic acid-acetic anhydride medium is complete, NaOH is adjusted to basicity, extracted with ether, and then extracted 3 times with dilute sodium hydroxide, combined with sodium hydroxide solution, added A few grains of sodium bisulfite, cooled to 5 ℃, adjusted to neutral with concentrated hydrochloric acid, precipitated acetyl-DL-tryptophan, refluxed in 10% sodium hydroxide solution, concentrated and crystallized to obtain DL-tryptophan.
