Description
Organic inhibitors can be adsorbed on metal surface by their electron donation and/or by their protonation. At room temperature, mercaptan can not be adsorbed on iron with electron pairs of its S-atom, but can be adsorbed with its active hydrogen attached to the S-atom. In previous papers, it was demonstrated that mercaptan changed to disulfide leaving hydrogen atom on iron. We dipped an iron tube in the mercaptan ether solution, and found hydrogen inner-side of the tube by means of its reaction with 2-butenal (CH3-CH=CH-CHO). Hydrogen penetrated into iron to contact with 2-butenal, which was preliminarily put in the sealed iron tube. From the analysis of n-butanal, penetrated hydrogen was confirmed, considering hydrogen previously existed in iron, which was estimated by blank tests carried out by dipping tubes in pure ether.
