    摘要: The method is directed to assaying for biological components in a sample comprising step (A) generating an oxidase substrate in the presence of an amphoteric surfactant and in the absence of ferrocyanide; (B) initially generating hydrogen peroxide through said oxidase reaction on said substrate of oxidase with subsequent detection of the generated hydrogen peroxide using peroxidase and a color developer capable of being oxidized in the presence of amphoteric surfactant and ferrocyanide; and (C) correlating the amount of color developed to the amount of biological components in the biological sample. Even when the biological component to be detected is present in a very small amount, the interference of bilirubin can be eliminated in assays of biological components in which peroxidase generated from an enzymatic reaction is detected using peroxidase and a color developer capable of being oxidized.

    摘要: A benzyl vinyl ether represented by the following formula is hydrolyzed in the presence of a catalyst selected among Arrhenius acids and Lewis acids to obtain 3,3,3-trifluoropropionaldehyde. Subsequently, the 3,3,3-trifluoropropionaldehyde is oxidized with an oxidizing agent. Thus, 3,3,3-trifluoropropionic acid can be more advantageously produced than in conventional techniques from an inexpensive starting material.
