A process which comprises contacting the surface of a metal with an alkyl or acyl substituted catechol.
The contacting may be effected using the substituted catechol alone or in a suitable medium for example as a solution or emulsion. The contacting is effective in provided corrosion inhibition even with lightly rusted iron surfaces.
一种工艺,包括使金属表面与烷基或酰基取代的邻苯二酚接触。
这种接触可以单独使用取代的邻苯二酚,也可以在适当的介质(例如溶液或乳液)中使用。即使是轻微生锈的铁表面,这种接触也能有效地抑制腐蚀。
