Sodium Hydroxide → Sodium Tartrate

Participants

Reaction Conditions

Reaction Steps

Clean microbic cells obtained similarly to Example 3 were placed in 100 ml of an aqueous solution containing as the substrate 1.0 g of cis-epoxysuccinic acid and having the pH value thereof adjusted to 8.0 with an aqueous sodium hydroxide solution and agitated at 35° C for four hours. The substrate was wholly used up to produce 1.40 g of sodium L(+)-tartrate. The yield was 95 percent. The reaction mixture was treated by following the procedure of Example 2. The L(+)-tartaric acid consequently obtained was found to have an optical purity of 100 percent.
