L-Sorbose로 부터 L-ascorbic acid의 工業的 合成 方法에 關한 硏究 = A Study on the Industrial Synthesis Method of L-aScorbic Acid from Sorbose

다국어 초록 (Multilingual Abstract)

In the industrial synthesis process of L-Ascorbic acid from L-Sorbose, we point to a study about high yield according to lower production cost. In a synthesis process of di-acetone-L-sorbose from L-sorbose, we can reduce amount of acetone rather than conventional process of C.F. Cuiban and we gain high yield at low cost by use of calcium carbonate instead of sodium hydroxide. In a synthesis process of Di-Acetone-L-Keto-L-gulonic acid monohydrate from Di-acetone-L-sorbose, we use low cost sodium hypochlorite instead of potassium permanganate as oxidation agent and reduce amount of sodium hydroxide in oxidation reaction in basic catalyst.
In a synthesis process of L-Ascorbic acid from Di-acetone-2-keto-L-gluonic acid monohydrate, we have gained higher yield by use of sulfuric acid instead of hydrochloricacid as acidic catalyst and we have removed industrial problems according to use of hydrochloric acid.
