く軽減される。When this reaction is determined by gas chromatography, the product is sulfur, and since it is not a gas, only the disappearance of hydrogen sulfide can be observed.However, methyl mercaptan, which is a mercaptan, The formation of dimethyl disulfide is possible.
e-greru. In this case, when hydrogen sulfide is inhaled, odor-causing components are not released into the exhaled vagina, but in the case of methyl mercaptan, the concentration of methyl mercaptan is half the concentration of methyl mercaptan when dimethyl disulfide is inhaled. . Although dimethyl disulfide is not odorless, the odor is greatly reduced by halving the concentration and the difference in perceived darkness value.
