Method for inhibiting Corrosion of metals in contact with Aqueous Solutions of alkanolamine,To eliminate gasesacidos alkanolamine Aqueous Solutions of This method and application on Sulfur Heterocyclic compounds as corrosion inhibitors that are included in these Solutions

摘要

This is a method to inhibit metal corrosion. It contacts with aqueous solutions of acid gas, and adds an effective inhibitor (I) of sulfur compounds with different cycles in these alkane solutions, wherein R1 is O, NH, s or CX2, R2 is s or CX2, X is independent h, c1-8, acarilo c7-12, arilo C6-10 and / or cycloquilo c3-10, provided that R2 ess, R1 must be CX2, and R1 is O, n OS,R2 must be CX2 Cyclic compounds are effective means to inhibit the corrosion of metals in acid gas or acid gas, no matter in acid gas or acid gas.
