実験手順
The process is conducted in a manner similar to that described in Example 1 hereinbefore, except that 1 ml of the citrate buffer, 1 mg of cellulose modified with 1,4-dihydronicotinamide and 0.03 mg of 9-methyl-phenazium methyl sulfate and 0.3 mg. of salicylic acid are used. As a result, 0.28 mg. of 2,3-dihydroxybenzoic acid is obtained (95% as calculated for the starting compound) having m.p. 203°-204° C. The composition, in %, is as follows:
