抄録

At room temperature, mercaptan can not be adsorbed on metal with electron pairs of its S-atom, but can with its active hydrogen attached to the S-atom. The adsorbed mercaptan on steel at room temperature changed to disulfide leaving hydrogen atom while the hydrogen was confirmed by means of its reaction with the unsaturated compound in the tube. To catch the hydrogen directly, another method was adopted in this report. Disulfide was found in the ether solution of mercaptan in which iron powder or a stainless steel tube was dipped at room temperature, while hydrogen was confirmed by gas chromatograph analysis of gaseous parts in the experimental apparatus. That is, hydrogen-bridged mercaptan on metal was decomposed to proton (·H) and mercaptan radical (R-S·). The proton penetrated into the steel and the radical coupled to become disulfide in the solution. In the hydrogen entrance into steel S-atom played an important role. We supposed that these phenomena could have some references with the occasion of hydrogen cracking of oil fields tubular goods.
