Reaction Steps
The same reaction procedure as in Example 2 was carried out using 6.72 kg of sodium bisulfite addition salt of phenylacetaldehyde, 1.76 kg of sodium cyanide, 3.46 kg of ammonium carbonate, 22 l of aqueous ammonia and 19 l of water to give 5.02 kg of phenylalanine crystals. The phenylalanine content of the thus obtained crystals was 95%. (The yield of phenylalanine calculated based on the amount of a sodium bisulfite addition salt of phenylacetaldehyde; 96.3%).
